Larson 23' Deck Boat; 2001 5.7 Liter Volvo IO;SX Cobra Outdrive; 150 hrs; DRV #4202008697<br /><br />Several weeks ago my Trim gauge pegged out showing outdrive was all the way in the up position and won't move. I haven't been able to solve that problem but it's not my main concern now. This past Sunday, after being out all day for a season starting test run (everything but the gauge worked perfectly) I trailered the boat, put the trim up and took the boat home. When I went to drop the outdrive for flushing nothing worked. The outdrive will not move.<br /><br />I have very little knowledge about the trim mechanism but I know that usually most things with a boat are simple (a fuse, loose wire etc.) so I want to troubleshoot before going through the expense of taking it to a shop.<br /><br />Question is two fold: Is there a fuse somewhere that could have blown and if so where is it (couldn't find one labeled stern drive or any blown at fuse box) and what do you suggest I do first to ascertain the problem?<br /><br />Thanks

Re: Volvo Stern Drive Trim won't work

You won't find the fuses/circuit breakers on the fuse panel. The main 50Amp breaker for power to the pump is on the electrical box mounted on the starboard exhaust riser.<br />There is also a 10A fuse mounted on the trim pump itself.<br />The gauge problem is likely to be the trim sender on the gimbal ring. A test with an ohm meter will verify.<br />Volvo service manual #7743244 will be handy in the troubleshooting process.<br />You also have an EF Model engine & drive which is a 2000 model year for Volvo.<br />Here is a wiring diagram of your trim electrical system.<br /><br />
