This summer Bill of Rhapsody and I had a discussion going about the Master Fuse for the fuse panel and the "Motor Fuse" that shows up on the wiring diagram for the Yanmar. Today I was doing some of my once every 25 year maintenance and looked for the Motor Fuse.

On the 500 series boats it is located directly behind and under the air cleaner, in a GREEN fuse holder, black taped to the wiring harness, red leads spray painted mostly motor gray. Hopefully they didn't tape it more than they have on Vee Jay. [You have to take the air cleaner off to access it]

So if some day you turn the ignition on, and the oil alarm doesn't sound, and the motor doesn't turn, but your radio still works ... it may be just possible that this fuse popped or the fuse holder cracked.

I thought it looked good enough not to have to do a close inspection and take it apart at this 25 year check up ... will look at it again in 10 years.
