Replace impeller on DF25A

[Old Mud]

Any special requirements for replacing impeller on this engine ?

Thanks

If/when you do it, please post a few photos here. I've had the same engine for a year, but not replaced the impeller.

When my engine was new, I hung it on my boat in the driveway and put the foot in a bucket full of water. The water level was a couple inches above the inlets on the foot, but when I started the motor, it didn't pee. I turned if off and raised my bucket a couple inches and tried again; still wouldn't pee. This time I made what is probably a mistake - I thought maybe it wouldn't pee until the thermostat opened up, so I let it idle for 30 - 60 secs before shutting it off. Eventually I connected a hose to the flush port and started again - with the motor still in the bucket of water, and this time it peed as expected.

I've seen some reference on this site to a Suzuki characteristic (or maybe a known characteristic of ALL outboards?), that the water level must be not just above the inlet, but above the impeller, before the motor will pee.

Main thing with this or any other impeller replacement, is to make sure you bend the rubber impeller vanes in the correct direction when fitting the impeller into the pump case. There might also be some sealant requirements. but you need to check the service manual for that.

Old mud, what do you mean by special requirements? Yes, taking pics is a good thing to do as you progress.
If you have replaced impellers before, it should be much the same.
Your service manual will be your best guide.

2014... the impeller must be in water to operate. Water level must be at, or above impeller (above is best) to prevent overheating and damage to impeller. It is rubber on stainless, and will overheat in seconds without water. It is only water lubricated.

Good luck.
