Installation Notes

Always disconnect the battery negative terminal before starting work.
Drain the lower unit gearcase oil completely.
Remove the mounting bolts securing the lower unit (gearcase) and carefully detach it from the engine's midsection.
Unbolt and remove the existing water pump housing. Take note of all component positions.
Remove the old impeller, gaskets, wear plate, and any seals from the driveshaft and housing.
Thoroughly clean all mating surfaces and inspect the housing for cracks or warping. Replace if damaged.
Install the new wear plate and gaskets provided in the kit.
Slide the new impeller onto the driveshaft. Turn the shaft clockwise while pushing down to seat the vanes correctly.
Reinstall the water pump housing and tighten its bolts to the manufacturer's specified torque.
Reattach the lower unit to the midsection, ensuring the driveshaft and water tube align correctly.
Refill the gearcase with fresh marine gear lube.
Reconnect the battery. Test the engine in water, confirming a steady stream of water from the tell-tale port.

Troubleshooting & FAQ

How do I know if this kit fits my Suzuki engine?

This kit is specifically for Suzuki 60–100 HP outboard engines made between 1998 and 2007, including models DF60, DF70, DT90, and DT100. Please verify your exact model and year against the compatibility table on this page.

What are the signs of a failing water pump?

Common symptoms include a weak or intermittent water stream from the "tell-tale" outlet, engine overheating alarms, or a noticeable decrease in engine performance. A worn impeller is the most frequent cause.

How often should the water pump impeller be replaced?

As a general maintenance guideline, it is recommended to inspect and likely replace your water pump impeller every 1-2 years or every 100-200 hours of operation, depending on usage conditions (e.g., saltwater vs. freshwater).

Is the water pump housing included in this kit?

No, this is a repair kit that includes the impeller, gaskets, wear plate, and seals. It does not include the metal or plastic pump housing. You should inspect your existing housing for wear, cracks, or warping and replace it if necessary.

Can I reuse my old gaskets or wear plate?

It is strongly recommended to use all new components provided in the kit. Old gaskets can become brittle and fail to seal properly, and a worn plate will reduce the new impeller's efficiency and lifespan.
