1990 Bayliner 5.7 Shorting out

[The_Driller]

Alight here's a good snowball for the pros, scenario is; starting out the electrical problem very unnoticeable out on the lake running around for half an hour or so.... relaunched from the sand bar and then the problems become more abrupt, tach and speedometer start jumping, running about 3k rpms but it'll jump to 5k and bog for a sec oddly and repeat this repeat this till getting more turbulent and frequently and also water is building up in the engine tray short of the bilge. I stopped to restart the motor and it started to blow the ignition fusues, initially a 15 amp and continued to blow till I put on a 25 *note, fresh new motor 5.7 87-95 mercruiser and reinstalled alpha one gen 1.

You have something pinching a wire and grounding it out. Stop putting larger fuses in, your just going to burn something up.

Look around the motor where all the wires are, it's there somewhere.

Which fuse are you replacing?
