Timing Chain for 2018 Sea-Doo GTI P STD 90 900 - Replaces 420297086

Timing Chain for 2018 Sea-Doo GTI P STD 90 900, a direct replacement for OEM part number 420297086.

The timing chain links the crankshaft to the camshaft(s), keeping valve timing exactly in step with the pistons. Chains stretch with age and hours, which retards cam timing, costs performance and can lead to serious engine damage if it jumps a tooth.

When You Need It

• Rattling or slapping noise from the timing side, especially at start-up
• Cam timing marks out of alignment
• Tensioner at or near the end of its travel
• High-hour engine or any top-end rebuild

Fitting Tips

• Inspect the tensioner, guides and sprockets when replacing the chain
• Double-check timing marks before starting the engine
