Starting motor without water to stern drive

[EEOCRAM]

I have a 1974 Mercruiser 140hp 4 cyl I/O. For about 45 seconds ran without water, how much, if any damage was done? Had dog ears attached fell off when I engaged throttle to rev up.

Lesson two, EEOCRAM. A Mercruiser wasn't an outboard before and it still isn't an outboard. It was an I/O and it is still and I/O.

Please use the correct forum.

Moving this.

Ayuh,....

The Odds are that if the Impeller wasn't Whooped when you bought this boat last Friday,.....
It's probably Whooped Now.........

You need to get some looong cable ties, that the hvac guys use, and strap the muffs on; you have to cut them off each time.
Experienced on the muffs moving, here.

Would the impellar being damaged cause it not to move when I give it gas. Took the boat out was cruising along fine. Stopped to fish a bit, started it up and it would not cruise, just go about 2 mph and do a lot of bubbling at the trim. It would rev up but not go above 2 mph. Had to drive back about 2 miles to the dock that way.
