Re: Larson 89, Mercruiser - Diagram of fuse panel?
i think the wiring dia. ya want is in the service manual. ya want the dia. of the trim system. this is provided by mercruiser..
boat wiring dia. are either non existent or provided by the mfg. of the boat. these elec. systems would control everything that is not related to the engine/drive. ie. nav lights, bilge pump, horn, radio, etc.
so.
what engine/drive and year..

fwiw. my neighbor just got a 2011 glastron. his trim didn't work either... the repair was reconnecting the wiring harness back together that was behind the remote. the remote had been removed by the dealer to service the hr meter. they didn't get the trim button reconnected when they put the remote back together and reinstalled. don't count on that being your problem though. that was an example..
