Not sure how heavy the boat is, but it will definitely add some load to the tranny.

if you want to stay 5-speed, do a R150 (I don't like the 151 as a replacement due to shifter location). Will only add the cost of the R150-tcase adapter as the rest of the components should be of similar cost. You *WILL* have to move your center console if you position the engine first. I did this on my 86 and ended up moving the console BACK about 3/4". Moved the mounting brackets and everything. Very simple, hard to tell it ws even done. And allowed me the opportunity to put the engine exactly where I wanted it to be to use a clutch fan.

I used to be a manual guy, but I'm getting lazy as hell. <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" />
