Symptoms: In neutral, forward or reverse (engine off, on trailer, etc) I can grab the skeg and lift the outdrive up by hand with very little hydraulic resistance. I can then lower it back to the original position by letting it down (again, by hand).
On the water, I can put it in reverse and it creeps up - it doesn't pop up. Of course, I didn't rev it up to see if it would pop up.
In forward, it creeps towards full trimmed down position (slowly). I have to tap the trim up switch from time to time to keep the bow from digging in as I cruise.
History: Previous owner had replaced all exterior trim hoses. I have not checked for water in tilt / trim fluid. I don't have gauges set up to perform tests of the hydraulics as denoted in the Mercruiser manual.
My question to those experienced is this: Should I start by tearing down the cylinders? I suspect bad or rust covered check balls and springs in the cylinder piston assy. The cylinder ends have marks suggesting that they have been disassembled before.
I'm okay with working on hydraulic systems, but I'm not familiar with the construction of tilt / trim cylinders.
Guidance and help is appreciated.
