Title says it all. Removed the starboard side today. Was making a funny noise and spewing fluid everywhere. Is there anyone who rebuilds them? Just a thought. Thanks.

It's a Mercruiser model MEST1088M

I have had good luck on low hour or new pumps on ebay for great prices. Make sure the seller has good rep!

Well figured out part of the problem tonight. Seems the pump is fine...bench tested and works great. Must have had some air in the line combined with a leak either in one of the hoses, or one of the 90 elbow fittings. Trying to get some new fittings but don't think that will be an easy job

Pull the resevoir off and check the screens on the bottom of the pickup tubes. Over time the oil can get "sludgy" and clog the pickups which results in air getting in and it makes a horrific sound.

Did it. Actually found the pump is fine. The problem was air and water in system. Problem solved. Now I still have the leak to contend with...have a bad elbow on line into pump and another bad elbow on the back from trim tab to stern. Sending off to Pepe tomorrow. Hoping to have back so I can launch her next weekend. Wish I had a local place to buy fittings.
