thanks
Any idea what I should expect to pay for each drive if the problem is that shift upgrade and nothing else? I always repair my own stuff and have no idea what is reasonable. I just bought an old "90 29' Fever with twins 454's and am installing prochargers,intakes,exhaust,new interior, Aeromotive pumps and stuff and I am getting tired of spending,,but really looking forward to some high speed high profile(all polished Alum)boating(and embarassing some jerks).

If the drives are 1990 you may need to change the cones from the old 3 groove cone to the newer 6 groove cone along w/ shift plate. You'll need a new cone, new shift plate/springs, seal kit.Also might want to upgrade the old drive shift linkage to the new style "black" linkage (heavier duty). When you replace the shift plate don't forget to get 2 new allen bolts for the shift rod (not using long allen bolt when you assemble). New parts cost, around 450.00 to 475.00 per drive.

You can replace the just the cone? Not the intire cone clutch kit with gears? I had one weld up on me last summer (1991 bravo). I then I had to buy the whole kit. for $900.

I like it if I can just buy the upgraded cone as peventative mantanence on the other drive.

Not an expert, but had shifting problems on one motor last year after I bought my boat. The mechanic I took it too determined that the cables forward seemed to be OK, but the cone gear set that does the shifting was worn and causing the problem. You apparently can't just buy a worn part but the whole gear set assy. Going price around $900, I think more now. Anyway, replaced them and cables while I was at it. Everything is fine now.

You can buy the cone from a newer standard Bravo.Then I take the gears and bead blast the area where the cone rides. I take the new cone, put some fine valve grinding compound and lap it into the gear lightly(mark the cone and gear to match, when assembling).Been doing it since Merc went NLA on older cones. Works well.

Hmmmmm
