My exhaust and riser are dead on my 4.3l yamaha sterndrive! Does anybody know if there is something to fit on because I don`t find any yamaha exhaust in my part of the country?
The standard reply is to wait for Ken Nelson to check in, however with a bit of messing around you can fit merc gear to a Yamaha. I'm running merc manifolds on my Yamaha 5.7.

I had the same problem, cost me about 350 to get one custom made with 316 stainless. Cheaper the converting as long as you can find some one willing to make one.
