compression test

Ok, have done a compression test today, both cylinders were 155psi, is this normal for a 50hp ?
Have done other basics like change plugs, check butterflies open fully.
Will now change prop to try and get more than 4000rpm.
Has anyone tried a 4 blade prop on a 50hp ?

A 4 blade will lmake it hard to work out the right pitch. Stick to a 3 blade,manufacturers standard ally type prop 'til you've got a benchmark.
