Jul. 30, 2007 - curious to know... Do people typically re-gap their new plugs right out of the box, before installing them?

sounds like you hydro locked it and possibly blew out a reed in your engine intake or worse, you may have bent a crank rod. But before you go tearing it apart make sure all the water is out of motor and theres none in the fuel tank then put in a new set of plugs and see what happens,

Tools(1) A compression gauge (2) a spark gap tester.(3) A Clymer service manual for your engine. (you can purchase from your local dealer. I know all these are expensive but if your going to be a polaris tech you will always need them. Troubleshooting (1) check compression. Look at your Clymer manual for specific psi.all cylinders need to be over 100 lbs and equal each other within 5 lbs.(2) check spark. use a spark gap tester all cylinders should jump a half inch gap. if you have good compression and good spark, fuel is the problem nine
times out of ten.Ethanol gas is proven to stay stable in fuel systems for only 30 days in 90 + degree heat. Drain gas tank,clean fuel lines replace and replace all fuel filters. Polaris has a gravity filter under seat, clean it. Finally replace spark plugs, I know spark plugs probably don't look bad but this is a C.D.ignition. Fresh spark plugs means less resistance for the ignition system. The ignition system is week compared to automotive. Test drive polaris, if the problem is still there then there is further steps to take. If your polaris is fuel injected. Pull out your clymer manual. what is great about the Clymer Manual for Novice techs is it gives detailed info on your polaris. Troubleshooting tips and teaches you how your polaris works. If its carburetor then you should clean carburetors. Inside the carbs is another filter that needs to be cleaned. Its not difficult you just make sure you put everything back in proper order. take pictures if you need to.

Unplugged water tube, cracked water tube, bad drive shaft hull seal, hole/crack in the hull, cracked water box, broken exhaust jacket water seal, water tubes plugged in incorrectly, no cap on flush kit, broken fitting on motor,etc. Dry out the boat take off the seat and place it in the water and look to see where the water is coming into the hull.

my kawasaki 900 stx got no spark to plugs what could be wrong thanks

ok, dont know if this will help but, I had a sl 780 that did the same, if you have a newer sl 700 with the multi-function display, and electric readout for gas and oil levels on display this could relate to you.. my float inside the gas tank compromised to the gasoline it was surrounded by and become saturated and wouldn't float anymore, which in turn caused the low fuel sensor to ****** the motor and keep it from reving up.. i had the same thoughts as you as it was a mechanical error, but turned out to be electrical.. and instead of buying a new $250 fuel level sensor.. i just opended the electrical box and unplugged the grey wire and it reved right up.. and if not electrical.. a carb kit is in need
