Exclamation steering slop problems 1900 sr "2001"

I bought a boat so I asked for this lol...

I have a 2001 1900sr maxum with the 5.0l mercury engine attached to a mercruiser alpha 1 outdrive. This has power steering or steering assist.

If I push the drive back and fourth while on the trailer I get about 3 inches of play without moving the steering wheel. While driving the boat I have about 90 degrees of play at the wheel before I get a response from the drive. It is most apparent when driving and turning the boat from a left turn into a right turn like an "S" turn around an obstacle or another boat.

I suspect the power steering arm or ram. something seems off to me there like the internals are moving funky from the housing. The pivot arm to the drive seems tight but I can't tell very good by myself.

can the steering ram become loose? the housing doesn't move but the guts in the middle slide separate from the housing and the ram.

maybe the steering cables and gears at the wheel? There is a good possibility that all of the steering on this boat is original.

Welcome Aboard

From the play in the drive it sounds like the swivel shaft and possibly gimbal ring and steering arm are worn. Common issue. This is the time to replace the bellows, gimbal bearing and lower shift cable.

Under Documents of this site you will find Mercruiser manuals; look for the Alpha one to review what is involved.

There is also a kit made by JR Marine to replace the swivel shaft without as much disassembly that the manual shows. Mercruiser also make a kit for this job.
