Me too, almost bought one used but decided to hold off and ask any of you guys that have a transom mount version.
Also Blue was right about the weight, would not go larger or heavier than a 15 hp two stroke. I went with a 9.9 for my kicker because I need that for the Lakes here.
Be advised that most 15 hp outboards are the same as the 9.9 's just re-carbed to get the boost up.
You can go larger if you can mount it closer to the keel line, if you are mounting it on a bracket out to the side it will cause the boat to list.
With mine I plan to off set the weight with a livewell tank I'm putting in soon.
