I have a 2008 Glastron GT185 with a I/O Volvo Penta Engine 3.0GLP SX-A drive. The boat has been in the water about 4 months. The last time I took the boat for a trip the drive was slow to go down ( 20 seconds, normally 10 seconds), but did go down. However would not could back up. I did check the relays ,fuses, connections per the other threads, these seem ok. The trim pump is making a noise as if it is working. I got into the water and can manually lift the prop in the water and can feel the the hydraulic trim cylinders about 3 inches only. They do not move more that 3" even if I press the trim switch on the throttle. This is less than 50% moment during normal operation.
I am a little confused. The electrics seem o.k, the pump seems to be working, If I had no hydraulic fluid I would expect to be able to lift the prop up fully but cannot, the hydraulic cylinders move 3" manually so they are not frozen but move zero distance by the trim switch. I am going to take the boat our of the water but I keep the trailer 100 miles from the boat so it a pain to do this. I welcome any advice.
