I am looking into a new motor for my Starcraft sixteen foot F/S. The lakes I primarily fish are limited HP. After talking with a marina over the winter he mentioned the High Output 9.9 from Mercury. He told me the motors were designed primarily for a pontoon boat on these limited HP lakes. Does anyone have any experience with these motors? Are they worth the extra twenty percent in cost versus the extra power. I have to keep in mind that my hull weight is rated up to 80 HP so I am not going to move very fast anyway. How does the motor rate versus say a 15 hp? I appreciate any feedback
