Suzuki DF25A Outboard Engine Long Term Test
HTML-код
- Опубликовано: 19 сен 2018
- We've been running the Suzuki DF25A 25 hp outboard engine for three years, so it's time to take a look at what our long term test has taught us. Used on a 16 foot fiberglass boat - which is quite large and heavy for this engine - it's been awesome. Performance and fuel economy are excellent and it starts on the first tug. Tune in, to see our review.

I agree thumbs up I own 2017 9.9 EfI maintenance free besides yearly fluid changes
have the same problem with tensioner. Other than that my 20hp is awesome! 25 on the way. Burns less than half of my 18hp 2 stroke
Thanks for the update on the shallow tilt feature, I've run the engine on the boat and I'm still breaking it in. The manual says to change the oil at 20 hrs, what they don't show you is where the drain plug is located. I did find a knob on the lower left side of the lower unit similar to the yellow fill cap only this ones black and can be removed by hand, is that the drain plug? and if so looks like oil will dribble all over the lower unit...is that the case? Thanks so much!
I think you are looking at the flush port.
I just ordered one today, I'm wondering if the non power tilt model has the shallow drive option where you can partially tilt the motor for shallow operation like the new Yamaha F series motors
Can you tell me, Thanks!
Yes, it absolutely does.
Hi thanks for the review! Would you recommend this for my boat? We wanted the one with tiller, electric, and tilt which weighs 163lbs. It's a 1957 Orlando Clipper. Aluminum. Thanks!
I'm not familiar with that boat in specific so take what I say with a grain of salt, but if the weight and length is right according to Google (no more than 16' and under 500 pounds) it should be a great match. As you see in the video, the 16 we have it on is fiberglass and is quite heavy, so your performance should be a good measure better than ours. Good luck and enjoy!
@@FishTalkMagazine Thanks for the fast reply! I forgot to mention our boat was 13 feet. Thought that may be important. :)
That steering tensioner lever would get loose after a few hours of boating, I found the nut above the lever to fix the problem with a 12mm wrench. I need to look in to getting an extension handle, you know where I could get one?
Thanks for all your help and advice, my motor is all broke in now and I do love this little beast!
Interesting, I'll check that nut!! RE the extension - that one was the result of a search on Amazon, they have several options.
@@FishTalkMagazine It still kept coming loose so I put a tiny bit of red thread lock on the nut nut it stays put..problem solved!
I've been running my 96 Suzuki 3 cylinder since 96 no problem just water pump and spark plug great motor and will outrun a 40 horse Nissan 40 horse Yamaha
Lenny,
Do you know what that boat weighs during your test of the Suzuki DF25A ? If not can you tell me what boat it is so I can try to find the specs.
Can't say for sure because my search on the same came up blank - it's an oddball boat. It's called a "Flounder 16" and was built in 86 if I remember right, but when I traced down the VIN number it was in use by a different builder who said he never heard of it (which is not supposed to happen, those numbers aren't re-used). Best guess is its right in the 700 - 900 lbs range. Probably weighed less when built, but wood in the deck retains moisture (lots).
Have you tried any stainless props with that engine? I want to try the Solas stainless 4 blade 10 pitch. I've read really bad things about stainless with this motor.
We haven't, however, nothing particular to this motor should really be relevant to going with stainless - we'd do it without hesitation.
Hi Rudow, Have you done a comparison between a Suzuki 25 or 30 and the 20hp? I have a 13' fiberglass Livingston (catamaran) 350 pound hull that is rated for a 40hp. I am tying to decide whether to outfit it with a Suzuki 20 hp @ 96 pounds or would I be disappointed and wish I had the power of a 30HP @ 163 pounds. The 20 fits my transom and the frame size changes with the 25 and 30 requiring me to adapt a jack plate to the transom for the larger frame. I understand the 25hp and 30hp are identical as they just adjust the electronic fuel injection for the increase in HP in the 30. Any thoughts you may have would be appreciated. Tim
Hey Tim - we haven't run them on identical transoms, however, it really depends on your expectations. The 20 should have zero problem with getting 350 pound hull on plane but the 25/30 will certainly get you more speed. We're not going to make any guesses about exact performances, especially with a Livingston since that's an unusual hullform. However, we've done jack plates on small outboards and note that it can cause a lot of issues (tilt, tiller position) with tiller-steer models. If you have forward controls that's one thing, but if you use tiller steer we'd be wary of the rigging issues.
@@lennyrudow7519 Thanks for the feed back Lenny. I have an adjustable (vertical 4") jack plate mocked up in cardboard that I plan to fabricate out of aluminum that I believe will work well with a Livingston. I believe I have addressed the tiller clearance issues one would anticipate with the peculiarities with this hull design. I would send you a picture as it is interesting but I cannot figure out how to attach a picture to this format. The issue people run into with this catamaran hull is the turbulence created by the sponsons and finding the sweet spot for the engine cavitation plate.There is a keel that runs down the center of the tunnel hull which I am sure was developed to provide more laminar flow to resolve cavitation problems created by the sponsons on cat boats. Ideally, I need to set the cavitation plate even with the bottom of the keel but there may be some fine tuning depending on the loading in the boat and sea conditions. Others here have wrestled with this setting. Our water access is the Sailish Sea, Straits of Juan de Fuca, and the Pacific Ocean so the sea and weather conditions are continuously changing. I will utilize a 20" long shaft as when we get into a 4' to 6' swell off shore there is a tendency to have engine ride too high when cresting swells and cavitation results, so the engine needs to be set deeper for those conditions.Yep, there are a bunch of folks here who run skiffs off shore, just choose your weather carefully. It is about 12 to 15 miles across the straits to Canada and the sea state in the straits often mimics the ocean. The catamaran hull with 26" high sides lends itself to incredible stability in these sea states. There are periods of time especially in the summer when high pressure sets in and this area is like a lake. Go at first light as the wind usually comes up after lunch and things change quickly. So, recognizing all the variances, it is probably a good idea to have more HP to get home safely with some extra speed as running out 10 to 15 miles is common. I have wrestled with this decision for awhile so thanks for your input as the more I research it I think that the 20 is too small for my application.Let me know if there is a way to send you a picture if you are interested. BTW, Bob Livingston built approximately 75K Livingstons in Arlington Washington during the 80's and 90's so there are all types in various conditions around here. Perfect day skiff for this area. Thanks, Tim
Do you know the exact measurement form the mounting bracket to the cavitation plate above the prop?
No offhand, but you can find the specs and dimensions at www.suzukimarine.com/
great review i am think of repowering my 1977 loweline 16 ft jon side consul boat , hull weighs 385 lbs alum, was thinking of 30 hp ,
what do you think of 25 vs 30hp for my boat ? thanks 👍👍
My guess is 25 would be plenty of power for that rig with two or three people aboard, but if you really load it down and/or put four aboard, that extra little bit would be good to have. (Or, if you just want a few more mph at top-end!!) Enjoy the rig!
May be a dumb question but Im a little curious. When the boat is sitting in the water and fully tilted up. Is the skeg of the motor in the water or is it completely clear of the water. I just want to make sure that if I put it on a 14' aluminum boat, will it clear the water when fully tilted.
Hey Jason - on this rig it's 100% out of the water, but all boats are different and we can't say for sure that will be the case with yours. Nor do we know of a reliable way to find out in advance short of putting on the motor - sorry!
Hello,
I've just ordered a Suzuki DF 30hp ATHL and I need to know big should I do the transom?? Can you tell me the lengh of yours?(if you have a long shaft type)
By the book they say 508mm, but I ve mesured with a Suzuki 5hp and it has almost 590mm. I can't find a 30hp to measure.
Can you help me figure it out? I need a lengh of your boat transom.
Thank you
The one seen here is a short-shaft, but we'd 1000% recommend going by the book. It isn't safe to compare with a 5-hp, especially because through the years many of the manufacturers have made 5s and 9.9s with extra-long shafts intended for use on small sailboats. 508mm matches up exactly with what we're seeing (20 inches) for the recommended transom height, so that certainly would seem to be the right measurement. Good luck & enjoy your rig!!
I have this exact outboard and I want to go to a 4 blade prop. Can you give exact specs for the 4 blade prop you are using. MFG. Diameter, Pitch. Thanks
Hey Greg - it's a Solas Amita 10.2" x 11" part number 421310211.
@@FishTalkMagazine Thank You! Thank You!
Disregard that question about the oil drain plug, that one on the lower left side is the flush plug, duh, sorry!
Great power to rate ratio
Very Quite
I just purchased a DF25A brand new listed as non current, how can I tell the year or the date of manufacture?
Hey John - the first digit in the six-digit serial number is the key. Number 7xxxxx would be a 2017, number 8xxxxx would be a 2018, etc.
That boat looks identical to a old seahawk 16 I owned. I guess they sold molds a few times.
LOL - for sure!! C-Hawk does still make it, in both center console and tiller steer models. I'm 100% sure the molds are the same.
Hi, looking to purchase a tiller handle for my 2021 DFA25 HP outboard. Please help.
Hi, afraid we don't do sales, you'll need to check in with your local Suzuki dealer, or, we have found Browns Point Marina to be very helpful, if you're going the internet ordering route. Good luck!
Dude put a PFD on - make that good exposure for all boaters!
What pitch are you running on the 4 blade?
It's a Solas Amita 10.2" x 11"
@@FishTalkMagazine I tried using their prop finder. Still not sure. It would be great if you could send me the link so I get the right one. It would be a big help. Thanks for the reply!
@@seancastle1937 You can plug 4213-102-11 into the Propfinder; it's listed for sale here: www.boats.net/product/accessories/6E1K-SOLAS-4213-102-11
How can I get my hands on one of these. They seem sold out everywhere and I don’t know how to actually get one. I want a 15 inch shaft, white 25 HP with remote steering. Please help direct me to be able to buy one!
Hey Justin - we feel your pain, there's a serious shortage still going on out there for all sorts of outboards in many different sizes. Afraid the best suggestion we can make is to contact your local dealer, let them know your interest level, and get your name on the waiting list...
@@FishTalkMagazine I got on two waiting lists today. We’ll see what happens!
Would it be fine on my triumph 170 sportsman? I don't need a speedboat.
The published weight for that model is 1100 pounds as opposed to 900 for the skiff here, but the skiff had put on some water-weight (the deck was not in great shape when this video was shot) and had a lot of gear on it. It's impossible to say for sure without putting one on the transom but best guess is you'd see similar results but unlikely better ones, and you might be safer upping the ante a bit.
@@FishTalkMagazine thanks 😊
How wood it do with a 18 foot john
Hey Robbie - 18' is really pushing it (pretty big for a 25) if the boat has much of a load. A light aluminum jon with a couple people on board should plane out and get speeds in the teens, at best. The 16' this is on is fiberglass and heavily-built, and runs at around 18 mph depending on the conditions with one people and gear aboard, more like 15 or 16 with two or three people. Aluminum boats are usually a good bit lighter than fiberglass but if your jon has decking and is rigged with a lot of gear, or if you commonly have several people aboard, I'd suspect there's a danger it may not get onto plane.
I found it page 11 in manual.
Ah, cool! I was typing a reply as this came in!!
What prop do you have on that motor cause im looking for a new one
That boat is running a Solas Amita 10.2 x 11 aluminum four-blade. Most boats will have a 10.25 x 10 aluminum Suzuki, but this particular boat has a high transom and it ventilated in turns so it was swapped out for the four-blade. Part number is 421310211.
@FishTalkMagazine k i got a 16 48 semi v hull same motor and it doesnt plane out at all i figure i would change prop im sure weight distribution would help a little but my big butt cant go no where else but the back so i figure i would change prop to try and help it plane out im also gonna get a jackplate for it also soon
@@bloodandsweatoutdoors8158 That's odd, it sure should plane - a four-blade may help it get over the hump, but is there any chance the boat is heavier than it should be due to deck core saturation or a similar weight-gain issue? We have seen boats where that happened...
@FishTalkMagazine im sure thats a problem im gonna go threw it and remove weight from it out of the back of the boat like rewire my battery to the front i already moved my anchors and stuff to the front
@@bloodandsweatoutdoors8158 Good luck hopefully that'll do the trick!
Cool, I’d probably use a 40 or a 50hp on it
Hello, I'm looking into buying this Suzuki outboard. What is the difference between these models?
2019 Suzuki 25 HP DF25ATHS2 Outboard Motor
- 2019 Suzuki 25 HP DF25AES2 Outboard Motor
Hey Sergio - the top one has power trim and tilt, but the lower one (no TH in the model designation) does not.
Thanks for the quick response. I'm leaning towards the 2019 Suzuki 25 HP DF25ATS2 Outboard Motor, but I would love to also have a tiller handle as well. Would it be possible to add a tiller tonthis model? If possible, how much would it cost to add?
By the way, I'm looking to add this motor to a Bris 12.5 inflatable. I'd love to have a steering system and a tiller for different applications.
@@sergiomoran8851 That model is absolutely available in tiller-steer. You should consult with your local dealer about pricing, but it'll be less, not more, than a 25 with forward controls. As to switching back and forth between the two, that could be problematic... we're sure it's do-able but just as sure it would probably require some work every time. Another good question for the dealer!
I will definitely look into it.
Another question:
Would it be ok to mount this motor to the transom using the mounting bracket, screws and clamps it comes with, or would I have to drill holes in my transom to add bolts and studs as well?
I'd like to avoid drilling holes in my transom.
@@sergiomoran8851 As a general rule a 25 can be clamped on, no prob, but many people do bolt them for added security. That said, we haven't seen the transom of this specific boat and are assuming there's nothing unusual, on that count.
14.6 StarCraft does 29 with just me, honestly think the 20hp would be close enough
That's certainly PLENTY of speed for a 14 footer!!
Suzuki great outboard but EFI 9.9 15 and 20 or 25 hp need recall on high pressure fuel pump, very common fault
Man that's horrible, I have a heavy 15 ft jon loaded with a big plywood fishing deck and side boxes with plywood floor and battery, she's heavy , my 94 Mercury 25 HP goes 29mph per GPS, my hole shot is fast also
Wrong prop, you're bogging the engine. 4-blade also not needed on such a small engine and boat, just adds resistance.
Hey Shingnosis - that's a very heavy 16-footer with just 25 horses, and the stock three-blade had trouble getting it on plane with more than one person aboard. (I didn't want to put a larger engine on the boat since my kids, all teenagers at the time, used it whenever they wanted and I didn't want them blasting around the river at fast speeds). I actually tried 4 or 5 different props of varying types before settling on that one, which spins in the recommended WOT range and planes the boat with just about any load. While it's true four blades do add drag (not resistance) as compared to three and I lost a mph or two at top-end, overall it performs much better and still falls within the manufacturer's specs. On many repowered/unusual set-ups the stock prop is less than ideal; here's a good article that details choosing the best prop for a rig: www.bdoutdoors.com/choosing-propeller-fishing-boat/
