14360A73 14360A78 Fuel Pump for Mercury Outboard
Best for Mercury engines in the 30–300 HP range. This pump is marketed as compatible with Mercury 30–300 HP 2-stroke outboards and related part numbers, making it a solid option for owners upgrading to a proven replacement. It emphasizes stable material construction for wear resistance and durability. A caution note highlights brass fitting sizing; ensure the hose fittings match your hose diameter before purchase. Choose this if you need a direct Mercury-compatible pump with broad horsepower coverage and reliable endurance.
Carbhub 18-7350 Fuel Pump for Johnson Evinrude
This pump is ideal for Johnson Evinrude marine engines from the early 1980s and older 6–15 HP models, including specific replacements for Mallory and Sierra units. It covers 6–15 HP variants and certain 25–25 HP configurations from the era. Best for legacy engines requiring a compatibility match with older Part Numbers (397839, 391638, 395091, 397274). It may serve as a practical upgrade for owners maintaining classic outboards. A limitation is that compatibility is strongly tied to older engine families, so verify your exact model before buying.
Outboard Fuel Pump with Gasket 18-7352
Best for a wide Johnson/Evinrude ecosystem, covering many HP ranges from 20 to 140 HP with multiple model cross-compatibilities. This pump comes with detailed coverage for years 1968–1996 and various engine configurations. It’s a strong pick when you need a single replacement for a large family of Johnson/Evinrude models. A caution is that some listings emphasize broad compatibility, which means cross-checking your exact part number for your engine is essential to avoid mismatches.
JLM MARINE 438559 Fuel Pump with Gasket
Best for a broad mix of Johnson Evinrude engines, including 25–140 HP variants and multiple listed part numbers. The gasket inclusion supports a secure seal, which helps reduce leaks and priming issues. This pump is selected for users seeking a versatile replacement that spans several model years. A potential limitation is that the listing covers a wide engine spread; verify your exact model fit to ensure compatibility.
CULMKARI 438556 Fuel Pump for Johnson Evinrude
Best for Johnson Evinrude 20–140 HP sets, including 25–140 HP ranges with several listed replacements. The kit emphasizes compatibility with multiple Sierra-listed and 388268 references. Choose this if you want a replacement that aligns with common Johnson/Evinrude engine families, but confirm the exact part numbers in your manual to avoid misfit.
SeaSierra Boat Marine 14360A78 Fuel Pump Kit
Best for Mercury 2-stroke 30–300 HP applications when a kit-style replacement is preferred. SeaSierra positions this as a Mercury replacement kit with wide coverage across Mercury’s HP range. It is suitable for those who want a consolidated kit replacement rather than a single-pump unit. A caution: verify that the kit includes the specific internal components your current setup requires to avoid missing parts.
Buying Guide
- Engine compatibility: Match the HP range and model year of your outboard to the listed compatible engines to ensure proper fit and function.
- Part numbers and cross-compatibility: Several pumps reference multiple part numbers (for example, 14360A73, 14360A78, 437 etc.). Confirm the exact part number that your service manual or existing pump uses.
- Gaskets and seals: Some pumps include a gasket; others require you to purchase separately. A gasket-inclusive kit can simplify installation and reduce leaks.
- Material and durability: Look for durable materials described as wear-resistant and tensile, especially for long-term marine use and vibration exposure.
- Installation notes: Some listings warn about brass fittings and hose sizes. Verify hose ID/OD compatibility with your fuel lines and ensure hose clamps will fit securely.
- Compatibility range: If you own multiple boats or engines, choose a pump with broad compatibility within Mercury or Johnson/Evinrude families to minimize future replacements.

- Are these pumps suitable for older engines?
Yes, several models cater to older Johnson/Evinrude and Sierra-compatible engines. Verify exact model coverage to avoid mismatches.
