I wouldn't be unhappy. Might consider a de-carb.

Well that sounds good on the Compression....Was looking around a marine shop yesterday and seen some Carbon Guard will go get some and do a de carb today.

I would double check the compression as #1 may have a sticky injector and washing cylinder thus the higher reading.
