    So something has been bugging me for a while, but I keep forgetting to ask about it here. On my switch panel in the lower right corner is a switch marked "accessory" that lights when I select it, but as far as I can tell, nothing else happens.
    Does anybody else have a functional accessory switch and know exactly what accessory it operates?

    On our boat, we had that switch hooked up to some underwater LED lights. That is all it is used for on ours.

    I rather suspected as much. But since I don't have a bilge light and that spot has a blanking plate, I've been trying to figure out why there would be a switch in the accessory spot when (as far as I know) I don't have an accessory.
    Just one of life's little mysteries!
    By the way, welcome to clubsearay!

    Back in the day SR did not pack boats with options, they were often "dealer added options". The switch was in place for later options.

    So.....apparantly the water pump stopped working, overheated the engine and cooked lots of stuff in the outdrive, and also burned through the hydraulic line and the throttle cable. Lesson learned. Repairs are ongoing at the boat shop and will probably be around 2 grand. My boat guy recommended that I replace the pump every 2 years at a cost of about $300 installed, and this would ensure this doesn't happen again. Whatcha gonna do.

    Never realized the water pump was so fragile.

    Neither did I. Not sure if it's the Vegas heat or what, but I'm thinking a $300 investment every 2 years is much better than 2 Grand lol.

    Can't disagree with that! Mine is probably five years or more old. I'm going to have to look into this a bit further. I'll be having the bellows and trim gauges replaced this coming off season. I may have to add the water pump to that list, too.

    The exhaust fan in the head inexplicably quit working. I did clean a wasp nest out of the vent cover, but it wasn't very deep so I doubt it was the cause. It doesn't appear that there is any power at the switch, but I am unable to locate a fuse or breaker or any power source.
    Anybody with experience with this that can help?

    TIA

    I checked the wiring diagram and can't even find the fan on there. Found the Head dome light but thats it.

    Thanks for looking. I’m pretty much at a dead end on this one. The only other item I have that doesn’t work is the Bennett auto trim adjuster. Somebody has jury rigged the wiring for some reason so I have to figure out how (and maybe why) and put that right. Would sure be easier if I were a bit smaller!
    FWIW I asked my mechanic about replacing the water pump every two years. He said that was normal and I should plan on it too.
