    Question 1996 Sea Doo compression

    I have a freind with 130psi (pretty even) on a GTS (I think) her dealer says its low. It sounds like BS to me. what is the normal compression for this motor ?

    Check it yourself with a known good gauge. 130 isn't low, as you said the difference between the two are more important.

    Nearly every compression gauge you use will vary with readings... the most important thing is that the cylinders are equal, or very close!

    my 95 gtx and 94 stx both have about 120psi. They both run fantastic. The gtx will do a bit over 40 and the stx will do 45 gps.
