My motor just passed it's 3 year mark last spring and I had the full service with water pump replaced.
This fall I didn't get in to the water for last run and winterize.
I thought I'd be ok to run the motor a short while with a hose connected to the flush port in order to run the auto-winterize proceedure. But I didn't connect muffs to run water up from the pump..
It has occured to me that, while I likely had enough water thru the power head to ensure proper cooling, the water pump may have been insufficiently 'lubed'.
Is it likely that I may have damaged or at least prematurely worn my pump?
If I need to pull the lower unit and replace it for safety, I'd rather do it now than when the season starts and all the shops are backed up with work!!
The flushing procedure is explained in the operator's guide where you can run the motor or not when using the threaded flush port and a garden hose.
As long as you had the water running before starting the motor, your winterizing was successful and you did not hurt the pump. The pressurized water works its way down to the pump to lubricate the vanes for short runs at low speeds for such things as flushing out saltwater and winterizing the motor.

The manual seemed a bit ambiguous in it's clarity..that directly answered my question for future winterizing and running in the driveway!
To know the flush port can be used instead of the muffs is great peace of mind.
