rancheroxl, You are exactly right ! Mercruiser designs their outdrives to turn a max of 5200 rpms.
Lets say you are dealing with a 22 to 26 foot V- hull boat. Trying to get that beast on plane is like trying to pull an elephant on water skis. You need all the grunt you can get, Therefore you need plenty of torque from just off idle.Some of these boats will turn 6 grand,but not many. Even if they will ,they have to have the bottom end power or they're dead in the water.
