So each boat as a max they can put on the transom. Why is that?

Lets say my boat is rated for max of 400hp, but i want to re-power and put on twin 250. Could that be an issue? is it weight? or what?

Mininum or maximum :rotf2:

Thats insane

The reasons are structural, between the weight of the engine and the downforce applied to the tansom a boat is only designed to handle so much. The most dramatic effect from overpowering an outboatd is that you pull the transom off the boat!
