At least its you buddy's neck instead of your own. I blew the same fuse last month - operator error

You need to find out why the fuse blew. It will surely do it again unless you find the fault and fix it.

I also had this happen. It is my understanding, per MarineMax, that these fuses just blow every 5 years or so. You have the option to replace or just bypass the fuse all together. I replaced it just to be safe. And yes, you need to be an acrobat to change it!

Other than, don't turn your engine on in less than 3 ft of water, I haven't really gotten any good feedback for a fix.

Thanks
People epoxy off the low water pickups and drill holes into the water passage at the traditional location. Do a search on that topic and you should get good info.

Blue Thunder,

Thanks for the feedback. This is the first decent idea I have heard.

The next best idea was to put a pickup in the hull or at the bottom of the transom with a switch inside.

I will check this out. Where are you on the Bay?

Thanks,

NetGain

Northern bay area netgain. I boat out of a marina that gets ass low at low tide and I have never had a problem with what is sucked into the standard bravo pickups. A freind of mine in the same marina had big problems with sucking up stuck, epoxied off the low water pickup as I said, and no more trouble.
