Interesting article, Stigomery thanks for sharing.
From Inboard/outboards through many Outboards I have stuck with Mercury. Though, Yamaha's been catching-up on overall sales and can take a real beating and remain dependable. Also liked their two stroke engines as the oil/fuel mixture was 100-1.
Friends of mine that have or do own a Yamaha, lov'm. Yamaha used to manufacture Mercury engines 3-20 hp. I believe Tohatsu make the lower powered Mercs now.
