Yamaha 6N7-81800 Starter Motor vs A-Premium Starter Motor for Mazda 2.3L

These are starters for different engines, so the choice is set by your vehicle, not by preference. The A-Premium unit is a new 1.4 kW, 11-tooth clockwise starter for Mazda 2.3L four-cylinders, backed by a one-year warranty. The 519-CSM2395O is a 12 V, 9-tooth counter-clockwise direct replacement for Yamaha marine and powersport engines, rated at 4 Nm and 10,000 cycles. Buy the one that matches your engine's part number and rotation; neither fits the other's applications.

• Choose the 519-CSM2395O if you are replacing a Yamaha starter under part numbers like 6N7-81800-00 or 6N7-81800-10-00 on a boat or powersport engine.
• Choose the A-Premium starter if you own a 2004-2009 Mazda 3, 2006-2010 Mazda 5, 2006-2007 Mazda 6 or 2007-2009 CX-7 with the 2.3L four.
