I've got a 13' Gheenoe that's perfect for what I want to do around home. I've presently got a Briggs 5 hp 4 stroke on it, but I want a little more ump than this (it's does the job, is outstanding on gas, it just sounds like a roto-tiller goin up the river). I've compared the specs on the 9.8/9.9 hp Honda, Yamaha, Suzuki, and Nissan. The Nissan is 10 lbs. lighter (17 lbs lighter than the Suzuki) than the others and the extra weight is a big factor with me. It also has a 3 yr. factory warranty. I would appreciate any feedback anyone has to share. Thanks.
