Hi,

I recently bought a used bass boat that came with a 2002 150 XR6. I'm going over the engine to check the types of fuses I need so I have spares handy for when "Mr. Murphy" shows up while I'm on the water. According to the Clymers Guide, the Upper and Lower Voltage Regulators are supposed to be protected with 20 amp fuses, however, I found 30 amp fuses instead. I replaced the 30amp fuses with 20 amp fuses.

Any thoughts of why someone would want to use higher rated fuses?

Thanks.

Check with the dealer and have him see what size the parts manual or service manual calls for.  Don't depend on the Clymer to be accurate.

As for why would it have the 30 in the place of a 20, if it indeed requires a 20, somebody might have blown them and figured if the 20 blew, maybe a 30 would work better.  After all, it takes a lot more current to blow a 30, doesn't matter that 20 was protecting some high dollar electronics that could blow instread of the fuse the next time.  What's even more fun is when see a big ball of fire back there where the wiring couldn't handle the extra 10 amps the fuse was protecting.

My thoughts exactly so I put the 20s back in.  I'll call the dealer today.  Thanks.
