Having seen a 150hp on a 5.4m Searider, I have no doubt that they could take a 115.. however, I have driven many 90hp versions with decent props and have occaisionally hit 45 knots on flat calm days whilst trying not to get thrown out the boat from Chine walking...
Has anyone else used a bigger engine and what are they like? I used to have a 60hp on a 4m and that was bad enough.. however I it was an old early 90's engine.. not a modern lightweight..
