Power Steering turns left, but very hard to turn right??
 

I have the stock cable steering running into the mercruiser power steering unit.

Installed a new cable, much better.

Changed the valve on the power steering pump.

Still, no luck.

Any idea's??

the P/S control assy at transom is the only part that know diff in left to right....thats where your problem is...

what year is the boat? does it have the saginaw valve on the powersteering ram? is the zinc trim tab down by the prop there?
If it is the saginaw valve it will feed back steering torque, adj the trim zinc, it may help. which ever way the boat is pulling, move the back of the zinc in that direction.

It's a 1990, its not the steering torque, its only at parking speeds.

The zinc plate I have is the flat one, non-adjustable and clears the prop as well.

It is the steering unit on the transom, been there, done that.

yup, sounds like steering unit.

its the Brazil Valve. It can be easily replaced

Yes,

he stated it was a 1990, which is most likely the older style. He will need new steering hoses also, or find a way to adapt them, as the unit currently available has different size hose fittings.

Can my unit be rebuilt?

How can i tell if it is an older style?

Is it also called "Mercrusier steering actuator"??
