You taught me something I did not know. I'm fairly new to outboards. I have a 5HP Mercury (new) on my Solo Skiff. Still breaking it in. I did not realize that when the motor is in forward it disengages the lock and you can easily lift it into shallow water drive. I have been reaching back and lifting the lever plate to raise the motor a bit for shallow water. Don't have to. I just went and confirmed on my motor. This is great. Thanks very much.
Awesome! Thank you for the view and support! Good luck with your outboard, hope you really enjoy it!
Dude the underwater photage off the prop that is really cool
Thanks! Needed an excuse to play with the gopro a little :)
Excellent Tip Houston! Dope video!
lol thanks man, really enjoyed your last vid, that water was moving. Early congrats on 800 subs!!!!!!
Cool under water footage
Thanks! Appreciate the view
Very informative … great video !!!
Thanks again man! Appreciate it
Good info Houston. I just a got new 20hr Mercury last year, so I want to protect it at all cost. Great info buddy.
A 20-25hp Merc on a 16’ Jon boat is my dream setup!! You gonna take me out on yours? lol 😀
@@Skinnyriver We can go. My Grizzly is 14'. I just added my LiveScope on it. It get's around pretty good, even with me, 2 batteries, and my 2 big dogs, it gets up to 23 to 24mph.

A true gem of knowledge!! Just bought a used 12' aluminum jon boat and a new Merc 4 stroke 3.5 with a 5hp upgrade kit on order. I live Citrus County, FL swamp country in the Withlacoochee River Basin. Gets really shallow in some areas - popular with "mud boats". This easy little tip is worth it's weight in gold, for me!!!
Awesome! Thanks, let me know how you like your setup. I’m curious how you like the upgrade kit. Let me know! Thanks
@@Skinnyriver Upgrade kit 'bueno!' - markable difference. However, I can't find your shallow water trim mechanism on my newer generation Merc. No problem in the canals and lakes yet, but I hear it gets very shallow on the flats.
OK - found a trim adjustment. There's a three position pin adjustment on the cradle that the shaft seats on. Not too drastic, but I moved the pin aft, and trimmed the prop away from the transom a bit. It's not something you can do while in the water. Only three trim positions on the smaller hp models. I assume there's a reason? I also have a short shaft motor.
@whitehawkeFLA yeah I have a long shaft version. I bet the short shaft is limited because the water intake is higher when you tilt the trim. That’s probably the difference is the short shaft vs long shaft

Wish I had a boat all I have is a kayak .... Great upload
Man my favorite thing to do is get my kayak out and float SFC. Beats taking the boat out any day.
I've a 15' skiff, a 17' KW, and a 26'KW. I find myself looking at kayaks constantly, but tell myself I'm to old, especially for the saltwater on one.
Start looking around. I've a friend that found a good Gheenoe and then a 4hp that didn't cost him as much as his kayak did when he bought it. It didn't happen over night, he was on 2-3 sales sites for 3-4 months, but it came together eventually.
Thanks for info... Good fishing 🐟🐟🐟
Thanks you, appreciate the view! Fishing is starting to heat up in TN. Hope it’s a good year
Hello Skinny River,great video...very informative.i have a question I have basically the same set up that you have.i have to ask how far is your transducer from your prop?I have been reading all kinds of different information on how far it should be from the prop.
If I remember correctly my garmin manual said 15” or more (horizontal distance from edge of prop to leading edge of the transducer on the starboard side). I think I landed around that 15” as I was getting pretty close to the edge of the hull.
Not sure this is a secret, but it is good info. It's something I learned the first day I put my long shaft on a jon boat. I still have to build a jack plate for it, but in the meantime, trim it up to beach it.
lol yeah “secret” is kinda clickbaity, sorry about that :)
@@Skinnyriver lol! I can deal with clickbait as long as there is some substance behind it, so it's all good.
You can protect your skol with a piece of angled iron clamped onto you lower unit..skol from MINNESOTA
Attention! No props were injured or killed in the filming.
Lol that part was edited out
I went 5 miles in shallow water drive at full speed. Whoops. I felt like and idiot. It’s a neat feature, I have a lot of confidence in it
lol did you not know the motor wasn’t all the way down? 😂
wrong thays good
How did the motor do pushing upstream in the current? The shallow water drive sounds great but I worry there will not be enough power to move upstream in river current. Stuck with this motor until I can save for jet drive!
It’s ok. It was pretty s decent current and I made it upstream, but if its super strong you won’t be able to match the current. But overall I have been in a situation where I couldn’t make it up
Protect your SKEG FROM DAMAGE
A useful video I've not had the guts to use mine in shallow water yet but good to know shallow drive works. Do you clean your engine after use with the screw in flush port ? If so be good to see a vid of how you clean and lube your outboard after usage. Thank you kindly keep up the good work 🙏
Thanks for the ongoing support! I honestly have never flushed motor. I’ve really neglected that. I only use in fresh water, not salt, so it’s not as critical but yeah I need to look at that more.
@@Skinnyriver yeah I guess its not as vital to flush engine after use in fresh water. I use mine in salt and I flush and lube after every use...also I'm a bit of a clean freak ha ha.
@@Skinnyriver not so important in fresh, but crucial in salt. I've seen motors ruined after their time in salt water, because of not flushing. New motors have more protection, but don't run an older motor in salt without flushing the same day.
Thanks for confirming. Curious, when damage from salt water where does most of the damage occur on the motor. Does the corrosion simply start to eat through the cooling channels in the motor?
@@Skinnyriver When corrosion happens the metal oxides are often ten times the volume of the original metal so if the motor is old enough to have any raw matal on the inside is is very likely to get completely blocked in the cooling channels. Once water cannot flow, then you cannot flush it our with vinegar and dawn so it is ruined.
I just ordered a Tohatsu 6 hp and will be running in skinny water (rapids). I'm going to raise the motor as much as I can with a 3" set back. This will also give it better performance. I will have to rig up a low water pickup. I'm thinking of a 90 degree tube facing forward. Hopefully, I'll have enough clearance in front of the prop. What think?
Man that’s awesome, I don’t have a lot of experience with low water pickups or low water nose cones they put on the higher performance motors, but it sounds like it will work really well. I’d just pay attention to clearance and if the tube causes any turbulence in front of the prop (ventilation). But it sounds like a awesome setup. If you really get into the shallow water fun, Tohatsu has a 6hp jet drive outboard that’s made for that kind of stuff. That might be my next motor!

I have a mercury 4hp that I’m going to do the 6hp upgrades to. I was wondering if you’ve tried the motor on any bigger boats and what was the top speed?
I haven’t but I have seen it on some 1436 aluminum Jon boats going around 14mph
Thanks for the quick reply. A 1436 is exactly what I’m looking for. Or a 1242. Love your videos dude, when I get out the navy I plan on getting me a Chanel up and running.
Awesome! Keep me updated when you get a boat or get some videos up. Thanks for your service

Hey boss, I see the Mercury 4 thru 6 HP motors have an alternator for charging or lighting. Haven't seen any video's floating around on that yet. Would make a good one!!!!
That’s a good idea! There are 2 versions of the Mercury, the standard and the sail pro. The sail pro has the alternator and 12volt hookup for charging. Unfortunately I don’t have that version. But if I ever get my hands on one I’ll definitely do a vid.
@@Skinnyriver I was looking at the specs on a 2022 4 HP and they show a 4 amp alternator for charging and lighting. Must be a feature added to the new models. Hope so any way. Just handier for the trolling motor battery. Tired of lugging it in and out of the boat to charge it.
@@agentorange2554 that’s cool, I learned something. Haven’t seen the 2022s yet. You are right, I have to take mine out as well. It’s a pain. I might have to look at upgrading myself
@@Skinnyriver Did a little more research. The alternator is optional. Since your motor is a newer model, it may be able to be upgraded easy enough. The motor at my local dealer comes with it. I'll be snagging it tomorrow.
The motor did not come with the alternator at my dealer. The dealer explained that the voltage is so low on that set up, you would have to drive around on the motor 9 or 10 hours to recharge your trolling motor battery. I swear, there's never an easy solution to anything!!!!
looks like you could lift the motor up 2 or 3 inches on the transom. the cavitation plate on the outboard seems to be way to low in the water.
Yeah I definitely could use a Jack plate. It’s about 2 inches low but it performs pretty good so I haven’t had a reason to justify the $$$ or time to rig something up. Good observation!
Look for diy on RUclips. Can be done for little money. Getting the hydrofoil on top of the water will give you speed, control, and fuel economy. May be worth a look. Will be building one myself soon.
I am new to outboards. I have a Tohatsu 5hp, 4 stroke (new). In shallow water position, I don't see water coming out the pee hole. This makes me concerned about using that position because I don't want my motor to overheat. Any advice?
You have to have cooling water peeing. It may be that your motor is sitting too high, there are short shaft and long shaft versions of this motor. Is yours a short shaft? If so it may mean you can’t use shallow water position because the motor is sitting too high because it’s a short shaft).
@@Skinnyriver yes. My motor is a short shaft. The boat manufacturer, Sea Eagle, specified short shaft (15") so that is what I bought.
BTW, I already hit bottom on my first trial run. Scraped up and nicked the prop pretty bad - sucks. Did not shear a pin though - thank God - I was 4 miles down river with no cell service. Can we talk?
That’s good you got the right length, the shallow water position is designed to keep the water intake in the water. So not sure what is going on with yours. I would test it out with the motor off. Put the motor in shallow water position close to the bank and get out and see if the water intake is above or below the water. But regardless, if it’s not peeing water, don’t run it in that position.
Yeah of course, my email is skinnyriveroutdoors@gmail.com, i could give you a call whenever
My 1980 Mercury 2 stroke 7th pisition rests the prop of the water.
I Wish there was a way to modify it
That’s stinks, not much you can do. You could look at getting an adjustable offset Jack plate but it’s probably not worth it unless your motor is too high in standard position.
buy ñew biat new motir
Just bought a 5hp 4 stroke mercury and mine does the opposite. When I’m in forward it locks in on the bolt and reverse it unlocks and will come up.. any help?!?!
Love the information you give on these outboards by the way!!!
Man that’s weird, what year is it? Some have a manual locking lever that you have to lock yourself. But if it’s a newer on (like after 2000) it should have a lever that is tied to your shifter rod that locks and unlocks it for you
You can MODIFY your transom with 2x12 clamped on to your transom with HEAVY DUTY c clamps..
Yeah good point, for many that would work. But My water intake would be too high it I raise it much higher. I am about 1” too low so I may try that to get my cavi plate level with bottom of the transom
Ever play with a mud motor on the boat
I’d love to, I see them flying all over our small River here in TN. Seems like they can go anywhere
How to know if a motor has this?
What motor do you have. I can check your manual. But if you raise the motor and it clicks and prop and water intake is still in water, it probably has this.
@@Skinnyriver thanks. I was looking at the 5HP propane model I found out it does have this which is great
Why not just add a DIY jackplate to raise the motor and get a straight facing prop instead of angles to the sky?
It might work but I would be afraid water intake would be too high and in turbulent water from to transom.
This is just a standard tilt position on all new outboards for when you occasionally get in shallow water. If you are always in shallow water probably best just to get jet drive
