Hi All,
I just wanted to add a few comments suggestions to people that have/are encountering this issue. The parts list Tom P and Smellson provided is money. A few things to keep in mind for anyone else going through this. The fill hole is the flat head head screw, not the allen above it (generally never need to touch the allen screw). Overfilling can cause seal failure or can split the housing. We were told that AW-32 hydraulic oil is better than ATF because ATF can cause seals to wear over time if they don’t have viton in them, which these don’t. After reassembling (I agree with being careful on disassembly as there is a lot of little parts) you will need to keep adding fluid (through the flathead screw hole) until it functions up and down properly. My unit would only go up a few inches at first but then I would add a little more fluid (aw-32) and then it would got a little higher, and repeat this until its full to the top of the flathead hold and trims up and down normally.
If you aren’t sure of your mechanical abilities, I would recommend sending your unit to 5 star Marine. The owner, Devin, is awesome and has excellent customer service and they can turn them around in 4-5 business days. They also rebuild with higher quality parts than OEM. I hope this helps someone else!
