Grand Sports center has a prop dyno they`ve been using forever. I don`t think Paul visits here too often but I bet he`d know how they run it. Ask for Mark I bet he`ll tell ya.

Otherwise do you have one of these close by ???

I'm guessing if he has a well prob not lol

Mine popped off the discharge side of the pump coming on plane and pumped the 27' full within 100 yards/seconds. Bilge pump ran for 45 minutes.

Never been on a well but yeah that makes sense! LOL

Off subject but when you`re on a well and your house is on fire the fire truck brings their own water and when they run out you`re sol?

"Well, were out of water, who brought the marshmallows and sticks?' lol

Trying to tie in all the bits and pieces others have said and from my own experience running on a stand with a Bravo pump I offer the following:

Pump flow rate is in the 10-70 GPM range.

Don't try to feed the pump, let it 'eat' from a large source/reservoir.

Keep the input flow from hose/well/ etc. at max rate

Try to recoup exhaust water to the max extent possible.

Total volume of reservoir will will determine max run time.

At idle to 1500 rpm I could drain a reservoir of about 2 x 4 x 1 ft dimensions with an input of 5 gal per min and recovering about 80% of the exhaust water in about 3-5 minutes. Watch the intake hose so that debris doesn't get in the way. I had a rag fall in the tank....ooops. Caught it quickly though.

Need to keep in mind, these flexible impeller pumps, flow a different volume of water when they are sucking, compared to what they flow, when being force fed, like in a boat at speed. .

Smitty, anyway you could simply buy one of those big plastic tanks, mount it up higher than the dyno, run a decent sized pipe to the engine area, and let gravity handle feeding the sea pump assembly, rather than trying to 'suck' the water from the tank? Then use a well pump to refill the tank back up when it runs low.

They call the fire department where i live " the foundation fire dept" because they can usually get fire out about when it reaches the foundation! Alot of houses out here have ponds for fire reasons , not just looks. To me its just a mosquito breeding grounds

As far as running on the dyno, the place that did mine had a tank about the size of a hot water tank that recirculated the water. The water temp rose from 165 to 175 during the pull. You can see the tank on the left
