The Honda 14781-PR7-A01 Valve Cotter is a genuine OEM component designed for BF135 and BF150 outboard motors. As an authentic Honda part, it is manufactured to the same specifications as the original, ensuring a correct fit and dependable valve train operation. Verify your motor's serial number against the fitment table before ordering, as Honda supersedes parts at production breaks across serial ranges. This Valve Cotter is the right solution for restoring proper valve retention on these outboards.
Key Features
- Genuine OEM Valve Retention — sourced directly from Honda, this cotter is manufactured to the exact geometry required to lock the valve spring retainer securely in place, preventing any play in the valve train
- Direct OEM Replacement — designed as a drop-in replacement for BF135 and BF150 outboard motors, fitting the valve stem groove without modification
- Serial Number Verification Recommended — Honda updates part supersessions at production breaks, so confirm your motor's serial number against the fitment table to ensure this is the correct cotter for your unit
- Valve Train Integrity — a correctly seated cotter keeps the valve spring retainer locked to the valve stem; a worn or improperly seated cotter risks valve drop, leading to immediate loss of compression and engine damage
A valve cotter — also called a valve keeper — is a small but critical component in the valve train of a four-stroke outboard motor. It fits into the groove at the top of the valve stem and locks the spring retainer in place, holding the valve spring under compression. Without a properly seated cotter, the spring retainer cannot maintain its grip on the valve stem, and the valve is at risk of dropping into the combustion chamber. Worn or cracked cotters should be replaced any time the cylinder head is serviced or the valve springs are removed.
