-   -   water pressure when running boat on the driveway (http://www.wakeworld.com/forum/showthread.php?t=67050)

I'm going to be flushing my boat after use, and was just wondering how much garden hose pressure I should use. Just open it right up? 1/2 way? I'll be hooking up the water to the seawater intake hose (pulled off of the grate). <BR> <BR>Also, are there any things I have to be careful of when doing this? <BR> <BR>Thanks <BR> <BR>Trash <BR>

You can't feed the impeller too much water! Open her up all the way. Make sure the cup does not "walk" off the intake BEFORE you fire up the motor. As soon as she starts, jump out of the boat and make sure the cup is still in place. It should take no more than 15 or 20 seconds before the water starts to flow from the exhaust. <BR> <BR>Keep an eye on the water flow! Also, be sure the telescoping support is perpendicular to the hull, not the ground.

I do mine at the cottage. I go full on 40 psi cottage water. <BR> <BR>Not sure about residential 80 psi water supply though!

I go full on with the hose.

i start with 1/2 or a little less and turn it up once the engine's running. the extra pressure while the engine's off isn't great for my homemade fake-a-lake. watch the garden hose and you can see if the engine is sucking the hose thin, if so give it some more. don't be shy.

I believe most residential water is 40-50PSI. <BR>80 PSI would blow out your sprinkler system in a hurry.

You're residential homes are usually 55psi and have a pressure regulator by the main hose bib coming from the street. Most appliances state anything over 60-63 psi will cause damage. So opening the hose bib wide open won't cause any problems.

The regulator at the street went out on us last fall, 170psi to the house, major problems.

Just keep it at idle. I decided to try and speed things up by uping the rpms and I ruined the impellar. That's two in the past year!<img src="http://www.wakeworld.com/MB/Discus/clipart/angry.gif" border=0> <BR> <BR>
