Got to hand it to the engineers on this one. 3 year old boat with the new emission package, cats, etc. operated very well the day before, the next day it was a no start. no fuel delivery, no fuel pump pre-prime sound. Everything else worked.
All engine breakers checked, all ENGINE fuses checked, engine relays swapped.
This lone fuse was sitting directly on top of the battery along with it`s spare replacement fuse in a plastic bag on the wire.
Originally thought it to be the bilge pump feed but following the wires it led up to the main wire harness. Fuse rating was 5 amps so it couldn`t be for the bilge pump anyway.
Removing the cover, it had blown the fuse from what I would describe as simply battery vapor corrosion and thats why it blew.The spare fuse also had heavy corrosion on it also and it was in plastic. Had a factory tag on the engine side as "clean power" ,guess the factory decided a direct battery connection for the computer was best.
Replaced with a jumper and boat now ran.
My fix was to cut away the fuse that was laying on the battery, direct connect the leads to the battery and install a new fuse holder on top of the motor near the other ones on the motor
Local marina wanted to try replacing the fuel pump first, an expensive guess. Guess nobody tries to fix anything anymore.
Just keep throwing parts at it so see what sticks.
Migh have to save and blowup the pic to see it better.
So ,if you have fuses laying on top of your battery, move them to a safer location before you get stranded.
