bought a 2001 Four Winns with 5.0 liter Volvo Penta, runs great, but the trim gauge is has not been accurate, although it does finally register full up, when up and only half down when full down. To accomodate this, we listen for the trim pump sound and the hydraulic "stall" to really know where the trim is. Last weekend noticed a different, weaker pump sound, which is still there, but no action at all on the trim, either up or down. Trim is all the way up. Ten amp fuse at pump appears OK. Any troubleshooting advice?
