My Searay 180 Bowrider 3.0 Mercruiser blows the ignition circuit fuse when I put it into gear. With a new fuse, it starts right up but the fuse blows again when put into gear.

What's the problem?

I understand from the dealer that there is a switch in the ignition circuit connected to the gear linkage that momentarily interrupts the ignition circuit to allow for easier shifting, and that this switch has a very sensitive adjustment.

Any ideas?

Thanks,

Ken

I am having the exact same problem with my Sea Ray 185. I was crusing on the lake and the boat went dead. I checked the fuse box and the ignition fuse was blown. I put another one and as soon as I tried to start the same issue happened. I looked all over for a short circuit or any messed up cable but could not find anything. the boat has less than a year and I have not done anything to it... like adding a new radio or any electrical thing. I will try to take to the dealer but they may take some time to fix it since there is a big waiting list...

I have been looking all over for a troubleshooting guide.. any ideas?

Swapped out the RUSTY stator in my Sea Rayder F16XR2's 150hp Mercury
Sport Jet and the fuses quit blowing. When the soft iron core is eaten
by the water it ISN'T PROTECTED AGAINST, it swells a pile of
rust...shorting out the turns, eventually.

When I replaced it with an aftermarket stator, I coated the new stator
in heavy axle grease, especially on the surface pointing to the whirling
magnets in the flywheel. The grease will level off but not peel off,
keeping the core separated from the OCEAN trying to eat it.

Charged battery much better....had really PAINFULLY HOT
spark!....stopped sputtering and would even idle, a 2-stroke magic
trick!

Pull the flywheel and see how much of the crap stator is left that's not
rotted away.....Curse Brunswick, again, for its cheap design.....

We are having the same problem with our 1998 Bowrider. Blew 20 fuses
and still had to paddle to shore last weekend. Problem started last
year and appears to happen when motor is warm/hot.

Still no answers or diagrams which help. Seems like when I put in
gear it dies.

Keeping lots of fuses on had and trying to have fun,

Calling the dealer this week. Let me know if anyone finds out
anything.

Have you guys tried swapping out the computer module to see if that
fixes it? That would be the easiest to test as it just plugs in.
Beyond that, I'd want to pull the flywheel off the motor and look very
carefully at the stator coils, especially on Mercury motors. Inspect
the soft iron core for ANY corrosion or swelling which trashes the
magnetism making the power.

My 150hp Mercury Sport Jet, which is just a V-6 power head bolted to a
jet pump from inside the boat, rotted its stator coils the flywheel
magnets pull against inside the flywheel. This is where the power to
run the ignition system and, separately, the power to charge the battery
comes from in outboards. Mercury, in Brunswick's infinite whiz-dumb,
has no protective coating on the exposed soft iron core these coils are
wrapped around that transfers the magnetic field from the whirling
magnets to the coils to make power. My core, as it rusted away from raw
soft iron being exposed to seawater and humidity, EXPANDED inside the
coils, as rusty iron will always do, and eventually shorted out the
magnetic field to the point where there was little spark and shorted the
coils as the extreme pressure exerted pulled the coils asunder from
INSIDE them. How stupid, Brunswick! I replaced the stator with an
aftermarket stator and coated all exposed iron with heavy axel grease
before re-assembly, much to the boat mechanic's dismay, to protect the
core from getting wet! Duhh.....(c;]

Never had an electrical problem, including fuse blows, after that...
Her spark was so hot from the Thunderbolt ignition it would bite you if
you were stupid enough to put your hands anywhere near those coils
behind the cylinders! HARD!

Just a couple of suggestions to try....

Removing the flywheel is a job for the proper puller and an experienced
technician so you don't screw up the top end of the CRANKSHAFT...capice?
It's NOT made to be hammered upon! (No, not me, someone else.)

If a man goes way out into the woods all alone and says something,
is it still wrong, even though no woman hears him?
