That was a 2 blade folding prop. How big / heavy is this boat? I would think you can do well with a 27hp engine. Are you making this trip alone? My boat is also in Warwick.Do you have a 2 blade or 3 blade prop?
My engine is 27HP 2 blade prop but I don't know how the boat will behave as there will be a lot of first times once I get on the boat this weekend.
