Problem fixed: Motor was hard to start and would stall under load
Replaced power pack and coils. It was very easy to do. I would never pay a mechanic to do these repairs because anyone with some mechanical sense can do this. The reason I was losing power under load was because my head gasket had a small crack in it. This caused a loss of compression in the top cylinder which would stall the motor when I put it in gear to go. Thanks to Crowley marine, I was able to easily locate the parts, find the EXACT RIGHT PARTS and their correct part number to get everything fixed.
