Severe Cavitation 1998 speedster

[houstonubc]

I've owned a 1998 speedster for 6 years now. I've had it serviced once a year and take really good care of it. Last year the right engine really started to cavitate. It takes for ever to get the boat to plane out, and if you have more then 3 people in the boat, it won't plane at all. We took it in and told them the problem. Here is a list of the work done on the boat.
2 new wear rings = $134
new carbon ring and bellow = $80
new drive shaft protector = $17
complete carb cleaning and service.
The total price for the job was $2239 with labor!!! I took the boat up to the cottage and it was no better then before. It still cavitates just as bad. Needless to say the company that worked on it and I had some words and I won't be taking it back there. I really want to do the work myself and fix it. I've looked over a lot of the posts and I'm trying to figure out what the problem could be. It seems like they did most the things suggested in the posts. What else do you guys think it could be??

How do your impellers look?

I haven't taken anything apart yet, but I'm guessing there fine if these guys didn't change them when they were working on it. Is it hard to take the impeller out?

Damn, I live in Ayr - sorry about your luck. You could always hit up the Better Business Bureau if they won't compensate you for a missed diagnosis.

I have to say I am really unimpressed with the repair costs of such an inexpensive boat.

I just got to be good friends with a guy at the marina who owns a Malibu and after seeing his boat its like why even own a Sea-Doo anymore?

He's put pennies in his boat compared to what I've tossed at mine. I spent as much to repair my boat, as I did to buy the boat.

dealer service and cost

I started taking mine to the shops and quickly discovered it is not cost effective for things I can do myself. Although I did have someone rebuild my motor i did all the R&R and that saved me big time. I also do all the pump work myself. I have pop off tester now and can setup and rebuild the carbs now. I have degree wheel and replaced my rotary valve and timed myself. I have spent the last week on an electrical problem (no spark) and am learning a bunch studying the wiring diagrams and getting advice from others on this site. I am confident I will have less money invested on this problem doing it myself and learning in the process than if I took it to a shop. It helps to keep my mind off work to
