Troubleshooting & FAQ

How do I confirm this kit fits my engine?

This kit is specifically made for Suzuki DT8C and DT9.9C 2-stroke outboards from 1988 to 1997. The best way to verify fitment is to match your engine's model and year to our compatibility table and cross-reference your existing part number with those in the Part Number Matrix.

What are the signs of a failing water pump?

Common symptoms include a weak or no water stream from the tell-tale outlet, engine overheating alarms, and in severe cases, steam from the exhaust. A noticeable drop in engine performance can also be an indicator of cooling issues.

How often should the water pump be serviced?

For preventative maintenance, we recommend inspecting the impeller annually and replacing it every 1-2 years or 100-200 hours of use, whichever comes first. Service intervals should be shorter in saltwater or silty/sandy conditions.

Is this an OEM part or aftermarket?

This listing is for an aftermarket replacement, not an OEM component. It is built to OEM-level specifications with comparable materials and manufactured in an ISO 9001 facility, with batch inspections for quality assurance.

We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free for most regions. Expedited options, where available, will appear at checkout.
