Small boat motor setup?

[Jarv121212]

I have a small 14 foot aluminum boat. I plan on taking it fishing quite a bit this summer and i was wondering what would be the best hp on a gas motor for my situation. I want to be able to get to a spot and not feel like im going at a snails speed and ill probably do a little trolling with it as well. it also has to be decently lightweight because i plan on taking it off the boat often. i was thinking a 10 hp would work best but i just wanted to get some opinions before i decide. Thanks
