I trying to determine what size engine I should get for my 22 Hunter. I do mostly day sailing, single handle in the barnegat bay and Toms river area. I found one used that is a Johnson, 2 stroke, 20 inch shaft, electric start.. The guy I bought the boat from says a 9.9 is too large for the boat and I should get a 5 to 7 hp and a 4 stroke. Any input would be appreciated. ThanksJim
