!40 Mercruiser and I/O

[McGillicuddy]

Find an old bt4 from a bread delivery van. $2-3 grand. 750 lbs of econo-muscle. Marinize, supe-up a little, and presto, a 150 hp, 265 ft/lbs of torque tank. Get a big as prop and occasionally visit a fuel pump

yeah, they are a lot bigger and heavier than a 140...
but boy that does sound sweet

That would be awesome but much too heavy...I fear I wont find a diesel light enough....heck the guy swears there is 100 in all cylinders...that oughtta be good for awhile...Im more of a slow cruiser...stretch that dollar..I plan to rig this one to travel...weight is a huge deal really.

If you ever had to replace the 140, the best candidate is probably the 4.3L V-6 based on the old Buick 90 degree V-6, which I believe is the 350 cu. in. V-8 with a couple of cylinders sawed off. It'll fit in the same place, is lighter than the 140 and should be about 200 hp, so boat would be a rocket with that power, although maybe a bit thirstier! Another member on here up north had one with that power and it looked like a pretty nice rig!

the MPI 4.3 is 225 hp at the prop with an Alpha

and 4.3 is also 300 lbs lighter than the cummins... light is right, brushhippie - you're headed in the right direction...
