I have had the o-ring on the body to tank leak on a couple of power steering
pumps. They are not hard to change. If it is a GM power steering pump, you
have to buy the special power steering pump pulley puller to get the pump
off. Any good auto parts store carriees them. About $10 after market, from
what I remember.

My boat has a 5.7 Volvo Penta engine and there is a power steering leak
somewhere. I have checked the connections on both ends and they appear
dry
but sometimes the bottom of the resevoir is oily. I'm told that there is
a
shaft seal on the pump that may becausing the problem. I have two
questions:

1. Is this seal easy to replace or should I just plan on getting a new
pump?

Replace the pump.

2. This engine is based on the GM 350 block. Can I substitute an auto
power steering pump which will probably be less?

Yes. It is not an electrical component and thus there is no ignition
issue.
