The best 4 stroke is a 2 stroke!!
The best make of a 4 stroke is to buy a 2 stroke! Yamaha 2 strokes are simple, powerful, lightweight, very reliable & burn a 100:1 mix of synthetic blend so are relatively clean burning and are far more simple and reliable than a bulky, less torque 4 stroke. I purchased a 4 stroke last summer for my RIB and sold it three weeks later! Yamaha two strokes are still available in 8hp, 10hp & 15hp. Oh yeah and my 4 stroke did NOT get anywhere near the rated GPH burn that the 4 stroke proponents claim and was virtually identical in fuel consumption to my two stroke..
