compression for 93 120 rude

[Lucrestyle]

1993 120hp evinrude, motor runs great! i did a compression check today as a point of reference

every cylinder was 125psi is this good compression? or should it be alot higher, i only turned the engine over for 2-3 seconds twice for each cylinder.

thanks again guys

Equal numbers with less than 10% devaition is more important then the actual number. I'd say for a 93 looper that's good.

Thanks for your advice, is there any recommendations to maintaining this engine / creating better performance?

would new spark plug wires be a good idea?
a new set of spark plugs? the ones in it work fine.
some kind of engine carbon cleaner type shizzle made by rude/john that will clean her up?

have any recommendations to keeping this engine in tip top shape please post and again thanks alot for your reply!
