The
3GM30 has something like 27hp which is minimal
power for a Westsail 32. Had a Volvo
MD2b which was rated at similar horsepower in our W32. It got us around, would
power at 5 knots all day in moderate conditions but in no way would anyone call it overpowered. Delivered a couple of boats with 35hp engines and they were much better in maneuvering in close quarters with their larger props and more hp.
The
3GM30 had two different
transmission ratios available. One was around 2-1 and the other 2.5-1. Get the 2.5-1 and don't even think about the 2-1
transmission ratio. It's a significant difference in the size of prop that they will spin.
Sailor Chic, was your piston problem a wide spread issue with the 3GM30?? Have one of that vintage in my
current boat. Just what I need is one more thing to worry about.
