Perfect for Multi-Carb Outboards
Many 3-cylinder and V6 outboard engines use three or more carburetors. Rebuilding only one results in unbalanced fuel delivery — the rebuilt carb runs rich or lean compared to worn units, causing poor idle and uneven power. This 3-pack lets you overhaul all carburetors simultaneously, ensuring synchronized fuel delivery and smooth operation across the entire RPM range.
Frequently Asked Questions
Q: Does this 3-pack mean 3 sets of everything?
A: Yes. You receive three individually packaged, complete rebuild kits — each containing all gaskets, seals, and needle valve components for one carburetor.
Q: How many carbs does a typical Mercury 3-cylinder outboard have?
A: Most 3-cylinder 2-stroke Mercury/Mariner outboards have 3 carburetors (one per cylinder). This 3-pack covers the entire engine in one purchase.
Q: Are the kits individually sealed?
A: Yes. Each of the 3 kits is separately packaged, so you can rebuild one carburetor at a time while keeping the remaining kits fresh and organized.
Q: Does this fit V6 outboards with 3 carbs?
A: If your V6 uses the same carburetor model as the 3-cylinder applications covered by this kit, then yes. Verify your carburetor model number before ordering.
Q: What if I only need one kit?
A: Single kits are available separately — search for our individual 18-7750-1 listing. The 3-pack is designed for multi-carb engines and professional users who want bulk value.
