Questions on Compression
So I was reading Vmans thread on his exhaust valve issues (posted there also) .... but was wondering
1 - What readings are you guys getting on Compression for 1-2 year old 300x's (say 50-100 hrs) ?
2- mine is about to turn 86 hrs old, never had compression test but requesting my dealer do it. Likeyhood or occurance of low compression that you have heard of?
I will say that I bought the 300 over the SC Seadoos becuase of the upgraded internals and reliabity...Vmans thread is def concerning, but hey maybe you guys will tell me otherwise

I've got 140+ hours.
Compression on my dealers gauge was initially 145. We've been monitoring this roughly every 30-40 hours. All three are now 150 PSI on his gauge. My dopey gauge shows around 130. They are all even though. If you are still pulling good RPM's but your gauge shows low, it's probably your gauge, like mine.
I also did a leakdown, it was only 5%.
If you have been following the maintenance schedule, fogging it after EVERY ride, and keeping the exhaust system as dry as possible, you should be fine.

I hear ya Vic. There are some I wouldn't either, but we have a really good one down here. For the record though, I did my own Leakdown and Compression (albeit my dopey compression gauge reads low).
