Powersteering concern

[William French]

I have a problem with a Nitro boat with Mercury 225 hp motor. When idling in gear steering work normal as in easy to steer right and left, but when on plane the boat steers easy right and extremely stiff to impossible left.

Year and model please! This issue has been addressed. Unless you have a Verado, you don't have power steering. Steering torque has everything to do with motor height, prop choice, trim tab adjustment {if equipped}, trim angle, and boat.
