Ok, I've tried searching the posts for this one but I seem to only see those related to exhaust issues & I'm not sure that's what I'm dealing with so here goes...
'07 Speedster 150/215SC, ~ 50hrs, haven't done the SC washer changeout yet (no yelling, it's around the top of the list!)... had a cavitation issue & replaced w/ a new wear ring & impeller. 95% solved the issue, but found out while wakeboarding that I still can't WOT the thing w/o a problem:
When I hit the throttle out of the hole to any more than 1/2, I get cavitation and have also noticed white smoke from the left rear (looks like it comes from under the rear cover). The reason I don't think it's an exhaust smoke issue is that I only see it when the boat slips during WOT; absolutely nothing when hitting the throttle to 1/2 on takeoff.
Could one of you point me to a solution, or have you had similar issues? I've read of the cavitation issues from the impeller/ring, but what are other problems/sources that could cause it?
Thanks for all the great info on here, and thanks in advance for any help you can offer!
