7.4 Mercruiser Fuel Injected Bravo 1 outdrive, Wants to go hard left when you give it throttle. Really have to hold tight to the wheel and try to steer right to keep it straight. But if you let off the gas and you have any pressure on the wheel to the right, the wheel will yank right. Very dangerous. I think I have a hydraulic problem. Replaced hydraulic cylinder but no joy.
