    Serpentine pulley kit 3YM30
    "Serpentine Pulley Kit for all Yanmar 2GM, 2YM, 3GM, 3HM, 3YM series engines with closed cooling water pump"
    More different than the other manufacturers than you might think. All of our kits are engineered to get as much rotating speed out of the alternator as possible. To do this we design the crank shafe pulley to be as large in diameter as the engine layout will allow. We than design the water pump pulley to have a diameter that keeps the speed ratio between the crank shaft and water pump the same as it was originally designed. The alternator pulley we use is the smallest off the shelf pulley we could find. The best part is we use an automotive belt not some crazy hard to find industrial belt. We have never had a problem procuring a belt. Call any automotive store and have it in a couple of days, for cheap money.

    Pump Timer
    "12 volt 30 amp PumpTimer"
    A pump timer is a DC equipment timer. It is used to limit the run time of pumps and blowers that are not designed for continuous operation such as bathroom blowers, water system pumps, and sewage system pumps. This devise will prevent motor burnout during empty fresh water tank situations, evacuation blowers in the head accidently left on too long, vacuum flush pumps left running because the toilet valve is ajar and sucking air. Run time is adjustable from 1 to 30 minutes with a small screwdriver. Timer resets every time power is removed from the input side of the timer. Simply splice the timer into the 12 volt power leads of the device you want to limit. Designed, manufactured, and tested in Eliot, Maine USA.
