Highly suggest glassing in new beams for your engine mounts. Those beams tied into the transom act just as a car/truck frame. Once you apply the torque of a strong engine, there's a chance it could separate those old beams from the floor. You would be stuck right back to pulling the engine and outdrive again to replacing the beams and glassing them in. Can't wait to see the end result of your project. FREAKING AWESOME!!!!!

Aaron and Em, several commenters have talked about potential issues presented by the high torque of the diesel engine (beefing up stringers and engine mounts etc,) but an additional significant area of concern when putting a diesel in front of and alpha or bravo drive is the drive capacity to handle high power and more specifically, HIGH TORQUE. The bravo is a very beefy drive but only designed to handle so much torque. Subjecting the drive to drop throttle starts that load the drive above its torque limit can be problematic for reasons I probably dont have to explain to you. Make sure you check your specs for compatibility in this regard if you havent already. Mercruiser does make a special X and XR series bravo for diesel and high output gas engines. To my knowledge, mercury does not recommend the bravo for any diesel applications. Bravo X will handle gas engines up to 600hp and diesels up to 370HP. Not sure about the XR. Do some research. This is a challenging project. Im impressed with your skill and courage to take it on.

I will give ya a tip since your going this far when the engine is done add an adapter to the drain for the oil pan add a tube to bring it out beside the engine add a shutoff valve then add a longer tube that is threaded to that to add a cap just in case the valve opens for some reason, but the main reason is you remove the cap add a hose the you can crack open the shutoff valve then you can suck out the oil from the bottom and make it faster and easy to do oil changes !!

Check out the torque specs between both motors that will give you an indication if you need to replace the stringers. It will also depend on which prop you are using. The pitch will cause different stress levels. You need to research the correct pitch for the RPM you will have to maximize your planning speed and cruising speed. You could use a variable pitch prop but that is expensive but can be an option. By the way, a variable pitch prop makes docking and maneuvering so much easier. Hope this helps. Also make sure both motors are rotating in the same direction.

The rot in the stringer ends will continue to rot. The rot is a fungus,, .. It must be removed to last any length of time. It might be handy to remove the top off the stringer Past the motor mounts and use pressure treated wood to replace it... Simple is usually the best. Then lay matting with directional over it to cover the stringer. Also making a knee brace from the stringers to the transom while you are at it is a good idea too. (20 + years of boat racing, building and fixing here)

NOT a boat builder, but enjoy the stuff the Ship Happens couple are doing to their boats. They're rebuilding a wooden WWII Harbor Defense Motor Launch, and are replacing portions of stringers, frames and deck beams with scarf joints. They epoxy and bolt them into place. I'd think if it works for a 70-foot twin Cat ML, it'll work for your boat. I'd think some Coosa Board 'wedges between the back of the engine stringer and transom would be plenty strong when epoxied into place. You could drive a couple of long SS lag bolts from the back of the boat through the transom and stringer to hold things together even better, then 'glass over that. They also have a twin Cat speed boat they're doing work on. No hull work, but good info there, too. Their two engines are in an engine compartment not much bigger than the engine compartment on your boat, and turbo heat is no big deal there.

I think you are on the right path. More torque, better fuel efficiency and better longevity for what you want. Plus you can get about the same RPM as the big block because they originally used the 396 for the first generation of junk diesel engines. I'm glad that GM keeps the same Bell housing and still a similar side mount for easy swaps. But the most important thing is seeing Aaron back to working on a diesel again 😊.

Oh I’m so happy to actually see someone do a Duramax swap in something instead of swapping a Cummins!!! Everyone is always doing a Cummins swap instead of the Duramax swaps and I say it’s because everyone likes the simplicity of what all you actually need to run a Cummins!!! I see square body trucks out there with Cummins in them along with plenty of other vehicles out there but very rarely do I ever get to see a Duramax swap in any thing!!! I’ve always told myself that if I ever go putting a diesel engine in one of my square body trucks or even any one of my 1967-1972 Chevy trucks it would definitely be a Duramax swap for sure and definitely Not a Cummins swap!!! My Duramax I have now is a 2007 classic body style and I have had it since 2010 and it also has definitely helped me recover on my last truck that I had and ended up literally paying for it twice in full and that definitely put me in the hole badly but after selling that truck and getting my Duramax I have definitely been recuperating the money that I have lost on my last truck because I have had to do absolutely nothing to my duramax at all other than regular maintenance things on it!!! I’m definitely really hoping that I can learn from you on how you end up doing everything for the swap and maybe that will help me get a better idea on what I might need or what I might have to look for in putting a Duramax in one of my square body trucks that I have definitely been wanting to do for quite some time now!!! Awesome video for sure and I am definitely looking forward to many more videos on this build for sure!!!!

Hey Aaron, if you have some extra room in the height department I would like to suggest tying the the 2 stingers together. make 2 cross members to form a square and then do a triangle off of each stringer and out towards the sides of the boat. The diesels torque will hit a lot harder and lower than the gas engine you removed. I have seen different setups rip out an engine mount out of the stringer. The first time was a nice searay 42' that was converted from gas. Believe it or not I know everyone will have an opinion but use marine plywood and stainless steel for the square box (keep in mind where that oil pan extends. This is a great project and I will be sure to watch your progress.
