drive trim pump question, water in oil

[fund razor]

One of the things that caught my eye, you said your two pumps were slightly different, and the two pumps listed and explained were slightly different in looks, but completely different in how they worked.

Once I got them on the bench and started opening them up I realized that they are essentially the same pump. One was mounted higher than the other on the bracket and at first it made me think that the pump body was taller. It wasn't.

I have seen them smashed, torn and off before.

Did you ever figure out where the water came from?

Never did figure out where the water came from. But there are tiny vent holes in the lids, and I am thinking maybe years of a little intrusion at a time. They were mounted under the hatch/boat divide. No oil leaks out, and my smart friends tell me that if oil isn't coming out.... there is no way that water is getting in. There were small light colored blobs in the bottom of the res that must be liquified filter screen. I am not sure what else it could be.

I want to take a pic of the half-gone filter today. I'll post it.
