i have a 4.3m quintrex decent boat lands very hard but i go outside on a decent day with it i have rigged it with a live bait tank new sounder and a rocket launcher (coolest looking 4.3m boat ive ever seen hahaha) you would definitely want a 40hp which is what i have great motor my only beef would be i have a two stroke great power but now with better 4 strokes they are just as powerful 2 strokes are a pain to mix and very smokey and smoke alot even with the right mixture, hope that helps
