4BT Cummins Diesel Swapped Bayliner Boat!
Автокөліктер мен көлік құралдары
1992 Bayliner Capri 2050 with a 3.9L 4BT Cummins in it. the engine was in my Silverado that I have videos of on here too it was over 400whp in the truck. The boat will do around 55mph on gps at 3800rpm, it cruises really nicely at 35-40 mph though. engine was pulled from my truck both turbos were removed and a single HE341 was put on. I'm running raw water cooling and the engine hasn't been marinized othe that some zinc thread in plugs. I think the only reason the Alpha is still alive is because I'm definitely not getting all the power to the water it needs more gear or prop to do that but I'm pretty content with it now.
Engine specs: highly modded VE pump, 5x16 injectors, ported head, PDR camshaft, marine style pistons, head studs, 60# valve springs, air to water intercooler. I'd guess it to be around 250-300hp now.
boat specs: It had a 4.3L in it, Alpha 1 Gen 2 1.47 ratio outdrive from boat with a 350, Bravo 1 30 pitch 4 blade prop.

That would have so much more torque you should put a higher pitch prop on it for sure
Thats a pretty good video. Looks like your outdrive can handle the torque.
A fast tractor on the water
Smoke on the Water. 😎
This is awesome
dude this is so unique love it! sounds great also!
Definitely should do a video on how you connected to outdrive and mounted it all up! Im looking to do a similar swap in my 25’ striper!

It really wasn't too hard. Find a 4bt from a bread van that had a gm trans behind it and use that to adapt it. The bell housing will bolt up. I did have a custom flywheel/spacer set up because the adapter I got had an auto behind it. So I used the flex plate for the ring gear then a spacer then the redrilled 4.3 flywheel. But I do think the triangle piece would mount up to a regular manual flywheel too
Needs underwater exhaust. Also a boat that won't sink. 😂 Also you need to fire whoever filmed this in vertical format. Sweet unconventional swap. Bet you can pull a ton of tubers.

You must have a really steep prop pitch to make up for the lack of RPM. I bet it planes really quickly.

@@TehButterflyEffecti know the boat is junk but I wanted to try it with a cheap hull to see if it would work and it does!

Won't even get up on plane with a 19 Pitch. I need more pitch, it just plays with it even at 55mph theres like no load, the engine is on the governor at 3800rpm

What power is she making. I’ve got 2 marine 4bts that make 150hp @ 2800 rpm and i want to get them to make 200 each for my project.
