Standard Duty Inboard Starter with Gear ReductionThe inboard starter that will fit Mercruiser, Volvo Penta, OMC, Marine Power, and others. All GM engines with 14" flywheel using a staggered bolt pattern. Recommended for late model 3.0 Liter with 14" flywheel using a tail bracket. Can also be used in place of a 10MZT style starter with two long bolt staggered patterns. Mounting bolt kit MBK450 required if replacing 10MT.ARCO advises using a fully charged battery - A weak battery can damage the starter and starter solenoid. And to also clean all connections - A corroded connection creates resistance, lowering the amperage required for an efficient starting circuit. Features:Dynamically tested and packaged for out-of-the-box performanceNickel-coated and/or epoxy-painted to reduce corrosion Sealed to minimize water intrusionDesigned for long life and optimum performanceArmatures are tested to withstand 50 times operating voltages (12 volts)Replaces:BRP/ OMC Inboard Starter 984456BRP/ OMC Inboard Starter 986505BRP/ OMC Inboard Starter 3850525BRP/ OMC Inboard Starter 3853982BRP/ OMC Inboard Starter 3854751BRP/ OMC Inboard Starter 3855177BRP/ OMC Inboard Starter 3857747BRP/ OMC Inboard Starter 3860566DELCO Inboard Starter 9000735DELCOInboard Starter 9000762DELCOInboard Starter 9000768DELCOInboard Starter 9000789DELCOInboard Starter 9000819DELCOInboard Starter 9000821DELCOInboard Starter 9000839DELCOInboard Starter 9000840DELCOInboard Starter 9000849DELCOInboard Starter 9000885DELCO Inboard Starter 9000940DELCO Inboard Starter 9000884 (Hi-Perf)MARINE POWER Inboard Starter 0174-000MERCURY Inboard Starter 50-12121A2MERCURY Inboard Starter 50-12177A2MERCURY Inboard Starter 50-806964A2MERCURY Inboard Starter 50-806964A3MERCURY Inboard Starter 50-806964A4MERCURY Inboard Starter 50-812428A3MERCURY Inboard Starter 50-812604A2MERCURY Inboard Starter 50-822330A2MERCURY Inboard Starter 50-864340A2MERCURY Inboard Starter 50-8M8021116MERCURY Inboard Starter 50-807904A1MERCURY Inboard Starter 50-863007A1MERCURY Inboard Starter 50-99418A2PLEASURECRAFT Inboard Starter RA122015VOLVO Inboard Starter 3587625VOLVO Inboard Starter 3857747VOLVO Inboard Starter 3860566VOLVO Inboard Starter 3860764VOLVO Inboard Starter 3885317VOLVO Inboard Starter 3850525-1VOLVO Inboard Starter 3853982-1VOLVO Inboard Starter 3854751-9VOLVO Inboard Starter 3855177-6VOLVO Inboard Starter 3856004-1SIERRA Inboard Starter 18-6275PROTORQUE Inboard Starter PH130-0067MPPARTS Inboard Starter SDR0105MPPARTS Inboard Starter SAB0081*ARCO Assurance 12-month part and labor warranty protection
