Does anybody know what the normal compression for this type of outboard would be? Or where i could find that type of information.

Normal is even on all three cylinders. The actual test # for compression varies depending on the gauge.

Service manual states it should be :-

Cylinder Compression
psi [kPa / kg/cm2]

117 [800 / 8.2] ? 13 %

Place throttle in fully open position and crank engine with starter
through at least four compression strokes. Take reading for each
cylinder and verify specified pressure is obtained.
