Lower Water Pipe Seal 3B7-65014-0
Premium Outboard Cooling System Component
This Lower Water Pipe Seal (also known as a water tube grommet) is a vital component of your outboard's cooling system. Positioned at the base of the water pipe where it meets the water pump housing, this seal ensures a watertight connection, preventing exhaust gases from entering the water circuit and ensuring optimal water pressure for engine cooling.
Key Features

Questions & Answers
Is this a genuine original part?
This is a premium quality replacement part manufactured to meet or exceed Tohatsu/Mercury OEM standards for fitment and material durability.
Why is this seal important during an impeller change?
If this seal is missing or damaged during lower unit re-installation, exhaust gases can enter the water intake, which significantly reduces cooling efficiency and can lead to engine overheating.
How do I know if it is compatible?
This is the seal for the "Lower" position of the water pipe on the Tohatsu M25 and M60 (25 and 60 HP 2-stroke). To be sure, check the part number 3B7-65014-0 on your old seal, or send us your engine model and serial number and we will confirm fitment.
