    2010 Chaparral 216 SSI Bilge Pump

    many bilge pumps are mounted to a quick-turn base that you can turn and release the pump from the base. I have done this on more than one occasion and replaced the pump with the same. sometimes you have to pull the motor to get to the pump (or starter, or exhaust manifolds, etc)

    Changed plugs now no start

    Just an FYI. At 9 volts, the ignition will not work and there is no way to spin the motor fast enough. Most batteries are 100% depleted at 12.0 - 12.2 volts, and fully charged at 12.7-13 volts (depending on battery architecture). Below 12 volts, you run the risk of toasting the battery
