Re: Yamaha 15hp vs. 20hp
This is one of those lessons learned after I purchased a like new 6HP electric start merc. (from my 90+ yr old grandfather who put it on his credit card thinking he was gonna start clamming again but told not to pull start a motor because of his new pacemaker). I could not believe how heavy it was compared to my 4HP so I started doing the research.
I took it back to the Merc dealer and traded it in for a 5HP that was MUCH lighter.
So, IMHO, always buy the highest horsepower rating in the weight category.
I also always wondered about carb, and if you even need a bigger carb, or just new jets or other bits?
