Re: My Horror Story
I know the area a little and the boat. One of my racing crew had a PY 26 and a GM10. The Yanmar 1 lung is a pretty simple engine and sufficient for the boat. You should be able to motor the boat, if it is operating efficiently, at 5.5 knots all day long. Your engine cruising RPM should be 25-2700 rpm.
Over filled oil reservoir is a distinct possibility. Did you use the proper oil or fluid for the Kanzaki transmission. Is the boat propped correctly? Electric fuel pump on this engine? If the tranny was older,the transmission might slip if the gears have a glazed surface. Probably not the issue.
Going down the ICW is a daylight only proposition. Conservatively, you should plan on 35-45 miles a day. 3 days from Jax to NSB is an easy ride.
Get the engine fixed, go for it, and have fun. Tell your relatives to treat you to a seafood lunch at Bostons to celebrate your arrival in New Smyrna Beach.
