I've got a 98 Ficht 150, and hit a good size bolder last year. There's a slight dent off the side of the front of the lower unit- everything still seems to run ok, but the Hydraulic trim keeps drifting down. At fully trimmed up, it will take about 2 days to drift all the way trimmed down.<br />There's no sign of any oil leak, but I'm assuming when I hit the rock, I popped a spool in a shift valve or something. The manual release screw is tight.<br />Any ideas as to where to look, what to do, what to check?<br />The manual really does not get into too much detail.<br />Where (other than a dealer) could I send it to if I need to?<br />Thanks
