My 1990 Bayliner 3.0 Alpha One has some kind of issue with the steering. The steering is stiff in certain spots and when it hits the stiff spots it makes a loud growling like noise in the motor. It sounds like it would be low on power steering fluid but I can even find any power steering components on the engine. Does this motor have any type of power steering? The only external oil resivor I can find is for the power trim. Please help!
