I'm seriously considering putting a 10 hp 4 stroke on an 18 foot Sotar self-bailing urethane raft with 24 inch tubes. Total weight in boat will be about 1,900 pounds which is well below rated capacity.
ISSUE: I've heard from some folks that they have experienced several inches of water pooling in the stern of the raft when motoring because as the stern dips water comes into the boat from the bailing holes. Others have suggested this should not be an issue with an 18 foot raft that is fairly well balanced out. I really don't want several inches of cold Yukon River water under my feet for hours at a time.
QUESTION: Looking for any first hand knowledge/comments on this issue of water flooding the stern of a big self-bailer raft when motoring with about a 10 hp. 4 stroke, particularly anyone who has done this in a big 18 foot raft. Many thanks.
