Specs At A Glance

Good To Know

Q: Why should I rebuild my outboard carburetor rather than just cleaning it? A: Cleaning removes deposits, but rubber gaskets and needle tips degrade over time, leading to leaks and fuel bypass that only new components can fix.

Q: Is this kit suitable for multi-carburetor engines? A: Yes, but keep in mind that outboard engines with multiple carburetors will require one rebuild kit per carburetor.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
