What Happens?

If you put a 25 inch shaft outboard on a boat that is set up for a 20 inch motor? cavitation? drag? thanks for your replies. Abe's Rocket.

No cavitation, but lots of drag. Your performance will suffer as well with the lower unit that far in the water.

Just something to think about - get a manual jack plate ($300-400) with 5" of vertical travel and you should be all set. You really want the engine's trim tab to be within 1" of the boat's keel for optimal performance and fuel economy.

thanks for the reply. who makes the jackplates? outboard mfgs?

Abe,
My father bought a Rite-Hite last season for his 23 Sceptre. They are made by RM Industries, but there are other mfgs out there.

Here's the link for Rite-Hite...
