Save fuel and hours on big motor (Honda's are sweet by the way). Shop a long shaft 4stoke kicker that way you can draw fuel from main tank. 8-9.9hp more than enough power. 6hp probably enough but fuel tank built in(no good). I just purchased a 8hp long shaft Yamaha 4stroke for under $2500. It got good reviews from anyone I talked to. 3yr warranty too.
