Our PMGR (Permanent Magnet Gear Reduction) starter delivers higher cranking torque than direct-drive designs, turning over large V6/V8 marine engines reliably even in cold weather or after long storage. 【100% Tested for Marine Reliability – Ready to Install】 Every unit is tested with DV Canada professional equipment: load testing, solenoid engagement, and seal integrity checks. Marine-grade corrosion-resistant construction. Manufactured in ISO 9001 & IATF 16949 certified facilities. 【Installation Notes – Critical for Marine Applications】 Ensure battery is fully charged and all cable connections are clean and tight before installation – most marine starting issues are electrical. Confirm flywheel tooth(11) count and bolt pattern match your engine. Professional installation recommended. 【1-Year Manufacturer Replacement : Fast, Direct】 If your starter fails to engage, makes abnormal noise, or shows electrical issues within 12 months, we send you a new one – no endless troubleshooting. Marine-grade quality backed by manufacturer commitment. Restore Reliable Starting Power for Your Mercruiser or Volvo Penta Is your marine engine slow to crank or making clicking noises? A failing starter is often the culprit. Symptoms include: Engine cranks very slowly or won‘t reach cranking RPM Rapid clicking sound without engine rotation Starter spins but doesn’t engage the flywheel Intermittent starting after engine is warm Our solution – high-torque PMGR starter for marine V6/V8 engines This direct-fit replacement is designed for Mercruiser, Volvo Penta, OMC, and Crusader inboard/stern drive engines with 4.3L, 5.0L, 5.7L, 6.2L, 7.4L, 8.1L, and 8.2L V6/V8. The PMGR design delivers superior cranking torque compared to old direct-drive starters – ideal for larger displacement marine engines. What makes this starter different? PMGR technology – Higher torque, lower current draw, better cold-start performance Marine-grade construction – Corrosion-resistant housing and seals for harsh marine environments 100% tested – Every unit load-tested and solenoid-validated with DV Canada equipment Compatible applications (partial list) Mercruiser: 4.3L, 5.0L, 5.7L, 6.2L, 7.4L, 8.1L, 8.2L V6/V8 inboard/stern drive (GM-based engines) Volvo Penta: 4.3L, 5.0L, 5.7L, 7.4L V6/V8 inboard/stern drive Also compatible with OMC, Crusader, and Marine Power applications using GM-based V6/V8 engines OE replacement numbers 50-863007A1, 863007A1, 30433, 30460, ARC30433, 57-30433, 3660566-3, 3857747, 3885317, 6792BN, 9000839J1171, 6792B, SDR0253BL, 5399M-D, PH140-0017-D, 18-6275-1 Installation notes for marine applications Disconnect battery cables before starting – negative first Clean all cable terminals and mounting surface for good electrical ground Ensure flywheel tooth count and bolt pattern match your engine Torque mounting bolts to manufacturer specifications – do not overtighten Warranty 1-year hassle-free replacement.
