So over the weekend I raised my motor off the bottom 2 hole. I used the wood under the lower unit and the trailer jack to move the boat. When I got done my trim pump won’t lift the motor any more. The electric motor spins well but sounds like it has no load on it. Any ideas what I do to it. I don’t see and never have any fluid leaking from it. Help Rag’s

So none of the cylinders move?

I'm overwriting my previous reply... because I had the exact same thing happen to my motor this evening!
Let me guess, you raised your engine all the way up, right? (manual or power, doesn't matter) Then when you tried to lower it with power, you got the whirring noise, but no motion, right? Same with mine.
It just needs some hydraulic fluid.
My fix -- Opened the fluid reservoir, stuck the nozzle of the hydraulic fluid bottle into the hole, gave it a squeeze while pressing the trim button on the engine up/down a few short bursts. Put the cap back on the reservoir. This gave it enough fluid to operate the down-stroke. I then lowered the engine down as far as I could while still being able to stick the bottle's nozzle in the hole. Squeezed bottle while raising the engine all the way up. Put the cap back on. Lowered the engine part way. Removed the cap. Some fluid came out, but that's okay because a lot of foam was created when it was stuck up. I let it sit for a few minutes, then repeated the process 2 more times to get rid of the bubbles.

Buck. Sounds like the same thing. It was very out of the blue. But who knows if and when fluid had been added. I was going try adding some fluid to it tonight after work as that is the thing my Yamaha guy said to try first. But of course it started raining heavy about 1/2 hour before I got off work. Rag’s

I have not put the boat back in the water but my guy stopped by Wednesday and said he put almost 3 cups of fluid in it. (Free of charge) Hard to believe that it holds that much. He said he ran it up and down and it seams ok. I also got my prop back from Leading Edge. Rich said 1 blade was heavy and was 17. 1 was 17.5. 2 were 18. I will report back. Rag’s

3 cups? Mine only needed a once or two to function properly.

So I put my boat back in the water and the trim pumped worked great, just like it did in the past. I am not sure why it decided that was when it need fluid. Rag’s

Fluid loss happens over time even with good seals. When the cylinder is fully extended, there's very little fluid behind the piston to reverse it. Even a little bit of air is enough to keep it from functioning. It's good to carry spare fluid, and a large flat-head screwdriver if you need to manually release the pressure to lower the engine. (access hole on the port side of the engine mount)
