fcsob, I think I will try to use a halyard thru the compass hole first instead of cutting the cockpit sole. Will see...
Captain force, how many knots you can go with new Yanmar compare to old westerbeke.
My 4-107 is coupled with Paragon tranny P-24 ( 2,5 for 1 ratio) and 17X17 propeller.
What was your old set and new one?
