What should the compression be on this motor?. The maximum and the minimum? Mine is at about 110 on all four cylinders.What is considered bad and what is considered marginal? What was the original when new?

there is no published data. 110 on all 4 is good.<br /> 2 strokes dont wear like 4 strokes. not long after a ring starts leaking combustion gasses a rod appears through the block, unless the piston skirt self destructs first. but worn out bores and rings are very rare on a two stroke. they will go out of round and taper some but usually once the rings start sealing they will stay sealed unless an overheat or loss of lubrication occurs.<br /> the spec is 10 PSI difference from highest to lowest. however its common to see one bank 10 PSI different than the other.

Rodbolt, Thank You so much, I really do appreciate your time and answer. This forum,my Seloc manual, and ebay have provided me with all of the knowledge and parts I have needed to get this project up and running. Hope to see you all on the water next summer. This forum is THE BEST.
