At a loss...

The boat just died. I have no power to the engine, or gauges whatsoever. No click, no nothing, but all the accessories still work, blower, power engine hatch, trim tabs, lights, etc, etc... I reset every breaker on the panel, but still have no power to the gauges/engine. Obviously, I tripped a breaker, or blew a fuse somewhere, but I can't find it for the life of me! There is no "in line" fuse under the dash anywhere that I can see, and I found 2 in line fuses on the engine, but both were good, and the 50amp breaker on the engine didn't need to be reset... Now I am at a loss as to where to look. Any suggestions before I have to bring it somewhere...

There may be a fuseable link in the ignition circuit. A fusable link is not a "fuse" but rather a short section of wire that is designed to melt should to much current flow through it to protect against a potential fire.

Really as suggested bust out a multimeter that will be the only way to see if you have power going to and out of your ignition switch. If you have a fuse block I'd start there and make sure you have power where you should then go from there to the ignition switch and so on. Having a schematic in this case would be really helpful to map out how things are wired.

One thing to remember with a boat there really is no chassis "ground" it's typically operating off a floating ground, possibly in line off the engine block or off the battery itself.

I will be calling Nick at NW Marine. Thanks for all the tips and/or advice, appreciate it very much.

I third the recommendation for calling Nick, 207-266-1888.

He knows his stuff and is very good. Local marinas are using him for wiring and electrical issues. Good work and a fair price.

Turned out to be the kill switch lanyard somehow shorted out. All set to be back on the water this weekend!!

Yes, I will be looking for you! I hope your vacation remains uneventful as far as boat problems go... You have definitely earned it the last couple weeks trying to get that boat ready. Enjoy!!

Well it hasn’t been quite as uneventful as I had hoped we were stranded in the bay today with a no start while trying to swap out skiers for tubers this afternoon! I am thinking battery, might be alternator, but I’ll have her fixed up ready to roll tomorrow am!! We are up in Buzzels cove if anyone wants to meet up for a beer and shooting of the breeze!
