Running engine on trailer

I plan to run the engine on my 1996 XP while it is out of the water on the trailer. I have the hose connector adapter and hose shut-off tool for the discharge hose. Is the water running from the hose only for engine/exhast cooling or does it lubricate the impeller as well? If it does not lubricate the impeller assembly, how long could you run the engine without any water from a hose attached? I know the manual procedure attaching the hose and pinching off the discharge hose is only for flushing the system. I would like to run the engine for a few minutes without any water attached if it is not harmful while I check adjustments.

Anyone have any experience?

Thank you.
 
You can run it for around 5 min on the hose. Your right about the jet pump, since it's not in the water the bearings will get too hot running it out of the water for too long.

Just make sure you start the engine then turn the water on. Shut water off, turn engine off.
 
You'll find we have lots of experience here on the seadoo forum. Ryan is correct with his explanation. You can only run the engine for a short time(5 min) so as not to over heat the jet pump assy. You shouldn't need to run it for longer to do adjustments...unless you have a cup of coffee in you hand. Take the break when your done. :)

Thank You

This forum is great! Thank you for the fast response. I won't run it fo anymore than 5 minutes. I do not have a need to run it that long. For curiosity, if I did NOT hook up the hose, how long do you think I could run it?

Thanks again for your help

I hooked up my hose and had the water running, then started the engine, what kind of harm can that do?

Im not 100% sure about the 2 strokes, but just to be safe start it first then turn the water on. I know that on 4 stroke motors if you turn the water on first it can enter the cylinders and mix with the oil.

Well I did that with my 95 spi, could that be a reason why it bogs?

No, I doubt that it's the reason for the bog. If you ran the water first then started it, you'd have to run it for a little while before it'll dump into the combustion chamber. It has to fill up your exhaust piping first.

The bogging is probably in your carbs. Depending on what your set up is (they had 2 different configurations from 95 models). Have your rebuilt them lately? Have you made any adjustments?

If not, with that age, I'd say it's time for a carb rebuild. Oh, if you still have grey fuel lines (I figure, with all the hype in the forum, you've already read that one), get rid of them..........:cheers:
 
The guy i bought it from had it sittin' in his garage for 5 years... so yea its probably the carb. I'll get that rebuilt.... how much is the rebuild kit? And the lines are clear, i got rid of the grey ones:hurray:
 
b-4 you purchase the rebuild kit, get the carb/s off, carefully go thru them/take'n them apart, then decide, if you need to rebuild, upon inspection of gaskets/o-rings..etc, if good, clean, put back together and re-install, and go from there.
They might just need a good cleaning, and you just saved 65 buks...
