    Mercury Optimax 175

    Hey guys,

    Iím looking at getting a river boat and found one with a mercury optimax 175 jet on the back of it. The seller has paperwork from the local marine shop stating that the motor compression tested at 120 on cyl 1-5 and 100psi on #6.

    Iíve always heard of the 15% rule but given all the work that was documented on the motor and itís general appearance I wanted to get some insights from folks who really know 2 strokes.

    Thanks for the advice!

    I ended up calling a local merchant mechanic and he pretty much said the same thing.
