K&B

K&B nitro marine and outboard RC boat motors are available through MECOA, which manufactures the classic engine lines.

Founded in the 1940s, K&B became a high-performance standard for American RC boating and racing. The brand is currently owned and manufactured by MECOA (Model Engine Company of America).

Engine Types: Famous for both inboard marine engines and realistic nitro outboard lower-unit legs (such as the popular 3.5cc, 7.5cc, and 11cc/.67 models).

Design Features: Many classic K&B marine outboards feature unique clockwise rotation (matching full-scale outboards), Schnürle porting, and ABC piston/liner constructions.

Availability: Brand-new parts and select current production outboards can be purchased directly via MECOA Online, while vintage or used assemblies (like the K&B 3.5cc and 7.5cc) frequently trade on secondary marketplaces.
