Howdy,
my next project is getting an outboard onto a 15' Boston Whaler Rage (OMC turd jet drive boat). A few people have used a jack plate and installed a 50, 75 HP outboard, I want to install a swim-platform bracket with flotation and a 4-cyl inline mercury.
Found this on CL (for parts or use), just did a compression check, it's 120-130 in all cylinders. It is a long-shaft (funky spacer... is this removable and a short shaft lower bolted up?
Also, check out the lower engine mount yoke, the splined bracket is rotted out, from what I read the 75/90/115/125 motors all use the same bracket. The rest looks fairly rust-free (I am used to working on VERY rusted things).
My plan would be to abandon the oil injection, from what I read here that is possible since the two carbs that are not used while idling still allow some fuel in, which in a mix senario would allow for lubrication.
Ideally I would set up the bracket for a short shaft engine, beside additional draft, is there any disadvantage to a long-shaft?
Again, by the time I get this going I could very well find another engine and use this for parts. What years are similar to this for parts transfer?
Thanks,
John
