I'm considering doing the same to my boat but it is a bigger boat, 29 feet, weighs 10,000 lbs. I'm thinking of two 200 HP outboards. I'm very curious how much the out boards, when tilted up, add to the length of your boat.
What is the distance, with motor tilted up, from transom to tip of prop?
10 000 lbs..... Twin 250 or better twin 300. By no means am I an expert but I think a 30' Grady is that weight and twin 200 would take so time to plane and burn more fuel than pulling back the sticks on 300's.
