Running out of water

Is it OK to rev it for a sec?? like this: http://www.youtube.com/watch?v=m-OjT5hPqcc

Watching that video is like an itch I can't scratch.

The 5 gal bucket trick is good for about 60 sec worth of water at idle, plus whatever your water supply is adding, mine just about stays level with the water running at idle. Rev all you want just keep a eye on the bucket and stop before it runs dry. The rig with the valves should be built out of the same suction hose as is in the boat so it won't clamp shut from the suction, its the only thing I've seen that can take some RPM's safely. You can see a Flush Pro leak and the Fake a Lake would colapse the water hose.

I guess that's up to you whether it's worth the risk and what that short of a run will tell you.

I have rev'ed my engine a bit while using the bucket trick without issue - as others mentioned it just drains the bucket much faster, the 1" hose I connect to the input of the raw water strainer doesn't collapse, of course I'm only rev'ing it to maybe 2500 rpm for short bursts. Also note: I put the bucket on the platform so the RWP isn't fighting gravity by drawing water up 4 feet from the ground.

The more important thing to remember when doing this (along with making sure the water supply keeps up) is to make sure it's in neutral when you rev it, you don't want the prop turning as the dripless packing around the driveshaft is dry and could be damaged.

More clarity. The dripless packing has water flow to it but it might be dry when there is not enough water...the water comes from the RWP.

Regular shaft packing will always be dry.

The strut packing will always dry no matter the shaft packing.

Thanks airtool - I was trying to reference the packing where the strut? comes through the hull. I actually have seen a CC dealer engage the transmission while running out of the water - but he had an assistant continually spray the strut/packing on the under side of the hull with a separate hose to keep it wet.
