Upgrading the motor on my 8'8" inflatable, the motors im looking at are (all 2012 models) Evinrude 6hp,Yamaha 6hp 2 stroke, Yamaha 6hp 4 stroke , and a honda 5hp. I really like the honda because of the price, but i would really like a 6 hp, which one should i go with ? and btw i had a 2.5 merc 2 stroke on there now so one these will be a big improvement. I only use the boat as a tender to my bigger boat i should point out, and my kids like taking it out.
