Automotive Power Steering Pump?

[Liquid_force]

My power steering pump is leaking around the pulley shaft - bad enough that the system will be empty after a couple hours on the water.<br /><br />I'm just curious if it would be acceptable to replace it with a new pump from a regular chevy 4.3L or if it needs to be a marine part.<br /><br />Also, the pump is identified as being "metric". What does that refer to?<br /><br />Thanks

"metric". Is just That.... Metric Threads...<br />You could try a pump off a car, I think they "Move " the holes enough so the are Different.... Even thou they "Look" Alike....

A marine or automotive pump are the same.<br />Problem is - the out or pressure fitting - and<br />the return fitting on the pump must match your <br />old pump. If not you will have a problem installing pump and routing hoses. Take the pump <br />with you to auto parts dealer to match fittings <br />and hose angles. The pumps are all the same - but<br />they are 30 different hose arangements. Every power steering pump made in<br />the last 15 years has metric mounting bolts - marine or automotive. <br /><br />You will have to remove the pump pulley, and put<br />in on new pump. Most auto stores will loan you<br />a puller, to do so. Air impack gun works great.<br /> Have fun - Jerry

thanks for the info Jerry. I have another concern though. One of the local marine shops said the pump pressures are different for auto/marine pumps. Is that not anything to worry about?

why not reseal the one you have you can get the seals from several places, g/m one and seal supply houses in mi i use applied industries 248 332 0211 you get the numbers off the old seals and they will have the new ones. or marine salvage do a search the parts pirates will mail you one.

an automotive pump will work, the pump does not<br />know if he is in a boat or car. You can buy a rebuilt auto pump for $45 - or a new merc for<br />$250 just try to match outlet and inlet to<br />make installing easy.<br />Remember the pulley removal.

Appreciate the input. I ordered a pump from a marine salvage a couple weeks ago - didn't fit - the bolt holes for the bracket attachment were in different spots.<br /><br />So I contacted a couple automotive parts stores and both were certain it could be easily matched up if I just bring it in.<br /><br />Thanks

Bought a reman. automotive pump and put my original OMC reservoir on it with all new seals. Works like a charm.
