Re: starcraft 14ft with a 15hp mercury
I had a 14' Grumman Champ with a 15hp Mariner 2 stroke that weighed in at about 800 lbs that would plain out just fine with two guys and a cooler full of ice. It topped out at about 23 mph. The hull was aluminum but it had a full wood interior laden with seats, carpet, livewell, three batteries, trolling motor, etc. It originally had a 9.9 and even that would plane the boat although only at about 17 to 18 mph. You should be fine with the 15hp. on a 400lb boat.
