STD Piston Kit for Mariner 4 HP 6E0 Outboards

Premium-quality aftermarket standard-size piston kit for selected Mariner 4 HP 2-stroke outboards manufactured by Yamaha.

Suitable specifically for the Japanese Yamaha-manufactured Mariner engines identified by the 6E0 model/serial prefix.

The 761-8256M piston is cross-referenced to Yamaha standard piston 6E0-11631-00-98K.

Kit Contains

1 x STD Piston
Piston Rings
Piston Pin
Circlips / Clips

STD = Standard Size

Fits Mariner Outboards

4 HP – 2 Stroke

VERY IMPORTANT

ONLY FOR YAMAHA-MANUFACTURED MARINER ENGINES WITH 6E0 IDENTIFICATION.

The 6E0 application is important because not every Mariner/Mercury 4 HP engine uses this piston. Parts catalogues specifically identify 761-8256M with the Mariner 4A 6E0 family.
