Regardless if it’s a Suzuki or a Yamaha, you are over propped for your boat/horsepower configuration…2120SC loaded with gear, fish, and four people on a trip to British Columbia this summer. Wouldn't even get the boat on a plane. The moral of this is DON'T think the Suzuki is going to make a big difference over the Yamaha when comparing the same size motors. If in doubt, go with more HP.
