C V Joint as solution to make engine fit

[Marc B.]

The 5411 deisel I bought to replace a spent Atomic 4 sits almost 3" above the moulded bench area upon which the cusions lay. I anticipated an adjustment of up to 1.5" higher than the original flatheaded 'bomb, but it seems that for my make of boat that the shaft angles were not standardized and I ended up with one of the problem cases. I don't want to have a stepped down bench solution, nor do I want to hollow out the underside of the cusion that deeply. Has anyone ever heard of using a c.v. joint on the end of the prop. shaft to adjust the angle of the engine to remedy this kind of situation?Marc

Correct angles

Hello Marc: CV type joints have been used for what you describe, but the angles have to be correct. By that I mean if you take an imaginery line thru the center of the crank and drive shaft, they must meet at the CV joint. The run angles can be great, but they must meet at the center of the CVJ. Good luck red
