I have a 4.3M inflatable, boat only weighing 114kgs, nice and light, i have a 25hp mariner on her but im thinking of putting a 40hp mariner on, i get around 20kts with the 25 but need a bit more, What do ye think the 40hp will give me? im thinking around 30-35kts.
Also the engine weighs around 75kgs my max engine weight is 85kgs so im good there,However my max engine size is 30hp(2 or 4 stroke)
Im sure it will be fine but what do you think?
For some pics of the boat >>
