Good To Know

Q: Is this an original Sea-Doo part? A: No, this is a replacement timing chain tensioner guide made to fit compatible Sea-Doo applications, and OEM reference 420236501 is listed for cross-reference only.

Q: Do I need to replace other timing components at the same time? A: Tensioner guides are often serviced alongside the chain, tensioner, and related guides, so inspect all timing components before ordering.

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