Owner was heading for a serious overhaul of the lower units, I'd say its been a dream come true on a power package that has a lot of options in the future, outboards are the way to go with everything in 1 package.All in all, impressive and ready for Florida's boating environment. Liked the vidios and watching the work .
You got her done and driving around on outboard motors in just five days! The customer drove his boat with inboards one weekend and showed up the very next weekend with outboards. His friends were impressed for sure.
My general question about weight distribution. If a deisel engine was removed from a 40ft trawler and a couple of 25hp outboards were attached, would it be safe? Should the weight be replaced? Your thoughts.
very interesting job well done i thinking my bayliner 2355 i removed engine outdrive and use a 25 hp outboard as i dont really go fast, just 10 knots is perfect, i should have bought a houseboat. i do alot of boat touring and camping in norhtern ontario what you think 25 hp ?
Does this help resale much? With an older used outboard comparable to the cost of a i/o (hull worth; not figuring conversion costs) Thinking of doing this to a larson using twin ox66 motors. Im capable of doing it in my shop here in NC. Nice work serious.
Cannot tell you about the economy numbers as we have not gotten that feed back from the customer, however a speed gain at wot of about 9 mph was realized and cruising is reported as better because the outboards are more comfortable cruising at higher rpm. The boat naturally sits on a plane better now, the customer does not input down trim tab as before
I would love to do this to my Searay260BR, been having issues with the Bravo3, but the cost is the problem, it's more than the boat is worth to me. I'm looking at a 270 that has twin honda 225 on it this weekend. I enjoyed your series. Gives me more of an idea of what to look for to make sure it was done correctly. Wondering if you did it. Looks almost identical to this setup.@@SeaMonkeyMarine
So let me get this straight, you took out two 650 Lb engines and replaced them with two 600 Lb engines hanging 40 inches further rearward and your trying to tell us this will be OK ?? Unless you added 400Lbs to the bow, this boat will swamp in a following sea. It's going to be riding with it's ass way down!! Basically you just ruined this boat.
FYI the weight of a mercruiser 4.3 efi package w/ alpha gen 2 outdrive is 865lbs so this was replaced with verado 25 inch outboard motors weighing in at 645lbs. So the switch to outboards was in fact less weight by 440 lbs over all. Now consider the flotation of the sealed bracket and you have even a lighter stern setting. we did add a generator in the previous engine compartment that weight in at 110 lbs. It is difficult to calculate the buoyancy of the bracket as it is at many angles, however rest assured that it is more than the generator weight and also compensates for the engines being mounted 28 inches back, so much so that the boat when floated sat higher in the stern than before. the customer has informed us the the boat feels more stable sitting in the water than before. And this is without any weight added to the boat in any place. So yes i will tell you that it is ok. the boat planned quicker and rides better than before using little to no trim at all speeds. The customer has reported top speed of next to 50 mph which was not even close before (41mph). The motors install were 225 hp not the 250 that is stated on the cowling. these were used motors and this is the way they were purchased. The Hp rating on the 4.3 efi is 210 hp so we had a small gain at propshaft hp. hope this answers your questions
we bought used motor for 19500, plus we installed a generator. this affected the total bill. The conversion in labor and supplies to perform the conversion should be about 15000. the overall cost would depend on the motors purchase and rigging parts selected

Great job!! You saved boats life and extends it for 20 years more. Congrats!
Yes! Thank you!
Love the sound of the L6 superchargers !
Glad you guys made it through the hurricane safely! Looks like an impressive build!
Thank you!
Such a nice conversion. I do this to all of my bigger boats.
That was so cool to see. Great job guys.
Glad you enjoyed it!

Nicely done. Very clean

Greetings, where are you located, and how much do you charge for that conversion? It's great.
Nice!
What’s the scoop on the before and after performance/economy numbers?

How fast will it go
where you got the transom bracket from ?
Facebook marketplace- the main company that makes them is Stainless Marine
what does it cost to do this type of conversion?
Customer purchased the outboards and bracket himself then about $15-20k in labor and misc parts but it depends it can be less it can be more

What was the final bill too??? Those motors alone must have been $50k.

I am impressed. You guys really did a lot of work in a very short amount of time. Great planning and no drama. Really great videos.
Thank you
What you didnt show is how she sat. All the weight moved that far back...
