powerplay 25, how does it handle in the rough ?? water is quite rough in FWI

Actually the X dimension is the height of the crankshaft centerline to the bottom of the boat. X dimension will greatly effect the center of gravity. Propshaft centerline on the otherhand is the distance of the center of the propshaft to the bottom of the boat. It can be changed without changing the X dimension. The use of different drives, raised or lowered extension boxes, shorty drives, and drive spacers can very the propshaft centerline to the bottom.

wow, that's very complicated...

Who is going to Key West? We will be there with our 38'.

It handles rough water just fine. Just keep the motors tucked in. If the waves are large you have to back down your speed as the props will break loose.

I can assure you it is no rougher out there then it is running the Jersey coast.

hmmm about 2-6ft everyday

With your Outboards it is the relation of your props to the running surface. The higher the prop the less gearcase you drag through the water, also allows you run a little bigger prop since the whole blade area isn't loaded all at once. If you put a straight edge along the bottom and let it stick out as far as your gearcase you can see where your prop hight is in relation to the running surface. then some of the experts here can suggest what you should do.
