Re: Serial Number
Great, and just so you understand why all those numbers are needed, here is what they all mean.
On your engine, the spares I would carry would be Fuel filter, and a fuel pump relay, raw water pump impeller kit and assorted fuses used under the dash. That relay is the same relay used on both the start slave relay and the fuel pump relay.
A couple of long (3 feet) 14 gauge test leads with alligator clips on each end can come in real handy at times.
The trick about spare parts, is you have to have the tools on board to replace them.
The best spare you can carry is preventive maintenance. If you follow the manual on scheduled repairs, and keep an eye on the engine and drive, you probably won't need a bunch of spares.
