Description
The 3B2-87123-0 piston ring set (standard size) is a genuine OEM Tohatsu ring set (superseded by 3B2871230M) designed for rebuilding the piston/liner clearance to factory spec.
This ring set is compatible with M8B and M9.8B 2-stroke Tohatsu and NS models.
Use it when your cylinders have minimal wear so only the rings need replacement, not oversize rings or re-boring.
Trust Central Outboards Services to supply the Tohatsu parts you need.
