Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance in marine environments.

How do I know if it is compatible?

If your outboard is a 4hp or 5hp 2-stroke model (Tohatsu M4C/M5B or the equivalent Japanese-built Mercury), this is the correct kit. Check your serial number or existing pump shape against the cross-reference list.

Does this kit fit the 4-stroke models?

No, this kit is specifically for the 2-stroke models mentioned above. For 4-stroke models (MFS4/5/6), a different diaphragm kit is required.

Note: At 4boats.co.uk, we recommend verifying your engine's model and serial number before purchasing to ensure 100% compatibility.
