I have a 15 foot Lund with a 30 Mercury 4 stroke for the same purpose. A light aluminum boat is awesome for remote unimproved launches. I launched mine out of a beach once.

I am still a Mercury guy, but I am gradually learning that Yamaha is a better engine. I live on the big water. I know a lot of people who use Yamahas hard, and love the durability.
