Few seconds you'll be fine ... might want to check your impeller unless it's a one that's considered "run dry"/

You'll be going to the otolaryngologist for ringing of the ears.

Just before I put the boat in each time, I'll click her over, just to make sure she'll start. But only for one moment.

I think the biggest danger is damaging the raw water pump impellar. Most are not intended to run dry and will damage the impellar.

Strut bearings are water cooled I believe, and made of a plastic material. As with anything, heat is what kills it. So for a short period of time, I doubt any damage would be done. Your temp guage will be the indicator on your motor. But as noted, you'll tear apart your impeller before you overheat the motor if its not the Globe run-dry.

the strut bearings are water cooled and water lubricated. without being wet, very wet, they will make the worst noise you have ever heard. Even for just a second it will make your skin crawl.

The engine can take much more time with no water than the impeller. Just ask my daughter who started the motor halfway down the ramp one evening last summer. She then learned how to put in a new impeller at the dock.

Someone mentioned watching the temp gauge. I'm not sure if that works when there's no water in the block. I realize there's some residual left in, but when you start the motor some of that goes out the exhaust. My point is I don't know if I'd take the gauge as gospel.

Your right. The temp gauge isn't going to mean a thing. The impeller will fry before you overheat anyway.

I have a fake a lake and I am thinking of adding a home made flush pro type system to the boat. I have never looked inside a v drive engine compartment that much, I can do this somewhat easily on my direct drive, but could you un hook the hose to the impeller shove a hose in there and run the boat with the hose on. Eliminates the need to buy a fake a lake or install a flush pro, and lets you run the boat without worrying about damaging anything. Its certainly the most hassle way of doing it, but saves some coin. If youre just running for a few seconds to make sure it starts before heading to the water then I guess its fine.

A lot of us do just that. You just disconnect the V-Drive and attach the adapter (home built). Run it as long as you want.
