Performance & Practical Benefits

When you’re out on the water, you don’t want to wrestle with a stiff or unreliable primer bulb. This one feels right in your hand—smooth, responsive, and firm enough to tell you fuel is moving the way it should. The triple-layer rubber structure keeps the bulb from collapsing under suction, even on hotter days or when fuel demand rises.

The low-permeation material helps fight against the slow, creeping wear that often ruins lesser bulbs. It stays pliable, resists cracking, and holds its shape season after season. Even in cold weather, it doesn’t harden or become difficult to squeeze, so you can count on it from the first outing of the season to the last.

Installation is simple: just slip it onto your existing line, tighten the included clamps, and you’re ready to go. Once installed, it provides a steady, secure feeling that makes starting the engine quicker and less stressful.

Why Buy OEM

• Mercury engineers design these bulbs specifically for marine fuel demands

• Better long-term durability than generic aftermarket bulbs

• Reduced risk of vapor leaks, softening, or ethanol-related damage

• Consistent, predictable priming action

• A cost-effective upgrade that protects your engine and reduces troubleshooting

When boaters recommend sticking with OEM for fuel delivery parts, this is exactly the kind of component they’re talking about—simple, reliable, and designed to save you headaches.
