I bought a wr and had it in the water for the first time. It starts, idles and accelerates fine. But at 20mph or so it just doesnt go any faster. No miss, no rev limiter kicking in, At least I cant tell if one is.
full throttle doesnt do any better than 1/2 throttle.

Compression is 180 and 188.

Impeller is beat up on the leading edges. One is even bent at the outer leading edge. No noticeable cavitation. though

High perf Parts on a budget:
impeller? stainlless or aluminium.
Best reeds?
Carb and intake mods?
Pump mods?

Its the impeller, Even if all you can do is get under it with a dremel and take some of the rough spots off you'll see significant improvement.

Other than that what do your plugs look like?

Thanks, any good replacement impellers out there for a decent price?
The plugs are dark. Going to replace them.

I just picked up a new old stock original for my 92 on ebay for $35. If your impeller is that bad you'll probably need a new wear ring WSM makes one. probably part # 003-506

the only trouble I've had is on Yamahas I think you've got to send out the housing and impeller to get matched. I posted a question about this but havent got a reply yet

 

[randyb12]

got a link for WSM?
Thanks.
Hey, Scarab95
You want to part with one of those Solaris inpellers?
