mercruiser 3.0 circuit breaker popping out when blower is on any idea how to fix the problem
If that's the circuit breaker on the engine, then you need to do 3 things.
1. Replace the blower and/or any damaged wiring
2. reset the engine circuit breaker
3 (and this probably the most important one). Get anything that isn't part of the engine circuitry, as originally supplied by Mercury, off the engine power system and onto it's own supply.
Here you have a clear example of why you should never have 'non-engine' electrics on the engine circuits... Imagine you're out 10 miles and the blower shorted, or the wires shorted... It pops the engine breaker, and now you have no engine, and as the radios are also wired like that, no way to call for help.
And this is something I've said too many times...
Run a separate pair of heavy cable from the battery switch to a red and black terminal block to a convenient location, usually behind the instruments, and take radios, boom-boxes, nav lights, blowers, GPS, sounders, and anything else that wasn't part of the engine from there. That way, if you lose the engine, you still have radios etc to call for help, and if an 'accessory' fails, you still have the engine.
Here's what the back of my dash/instrument cluster looks like....
I have a pair of 6mm power cables coming into those blocks, and everything else (not 'engine') feed off them. The only exception is an hour meter. That needs to be run from the key, obviously...
Cheers,
