It uses a permanent magnet design with an aluminum pinion housing that has 2 threaded mounting holes, and it rotates clockwise to engage the flywheel. Running on a 12 volt system with 1.4 KW of output, this starter is sized to deliver reliable cranking power on the AQ145B, AQ151A, AQ151B, and AQ151C engine applications.\u003c\/p\u003e\u003cp\u003eConstruction is centered on an aluminum housing for reduced weight compared to heavier cast alternatives, while still standing up to the marine engine bay environment. The unit measures 9.02 x 12.99 x 5.98 inches and weighs 6.76 pounds, so installers replacing an existing Volvo Penta starter can expect a comparable footprint. Fitment covers the AQ145B (1979-1985), and the AQ151A, AQ151B, and AQ151C (1985-1989), all 4 cylinder Volvo Penta engines. This starter directly replaces the OEM Volvo Penta 840808-0 unit, making it a straightforward swap for boat owners and marine technicians servicing these engine models.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
