Steering Shaft Rusted 1994 90hp

[arzy]

Hello

I have a 1994 Evinrude V4 90 HP (E90TXARC). I have recently had the power head rebuilt and was running great, new impeller & thermostats, done 13 hours since rebuild.

I have commenced a job of replacing the steering shaft which is badly rusted. So gearbox off, Power head off. I struggled some what with the bolts top and the bottom nut (Steering shaft) but they are now off as well.

I have evinrude bits everywhere at the moment. I am going to paint all engine components before re-assembly. I am about to replace the Trim Tilt motor which is badly rusted as well.

My question is, since I have the motor in a pulled down state. What should I do as maintenance. When I replace the Trim / tilt motor should I replace other o rings? Flush new power steer fluid through?

I intend to replace the annode, seals in steering shaft (top & bottom), new nut on bottom of shaft (wrecked the one I had to get it off, salt water engine), power head base gasket.

Let me know if I need to replace anything else before re assembly. Thanks for a great forum and fantatsic knowledge base.

Re: Steering Shaft Rusted

I'm a little ahead of you - doing a rebuild/restore on a 1986, 120 model.

Sounds like you have it just about covered.

I would however, remove the inner exhaust housing and replace the gasket and the water tube grommet - a water leak developing as a result of the failure of either is not super common but does happen regularly enough that since you have her "all opened up" it's well worth the few bucks for the two components.

And really take a good look at the water tube itself. I have refurbed a number of salt run motors and have found a couple of water tubes corroded severely - to the point where one had a hole (burned) through it (previous owner wasn't too particular about flushing the motor after use).

So just ensure it's in (sound) condition - if not, now is definately the time to replace it. Some corrosion would be normal and ok - especially if it's going to start living in fresh water - but if you find any soft spots or can crush the tube with light pressure between your finger - swap her out...

As far as the T/T unit goes - clean it up - if it's functioning properly I would personally leave it alone. It's easy enough to get at, at a later date if it pukes a seal...

(meant to add - don't have a heart attack when you find that nut that you wrecked sells for 17 bucks and I think that was the "cheapie" from Sierra)
