I currently have a 91 Klamath 15 Adv SS with a Johnson 25 2-Stroke electric start. I am thinking of replacing it Wth a 4 stroke. My concern is Weight. Since four-strokes are a bit heaver how big of a motor can I get and still be able to get to a plain at a reasonable speed/throttle position?

with two people should get on plane easy. But with more weight, still probably be able to plane but not as fast. you can go bigger than rated, like a 50hp but would be liable if an accident occurred.
