Sea-Doo US GTI SE 155 - Answered Questions & Fixed Issues

Water could be getting into the engine from the exhaust system which may not be totally drained. Remove the exhaust pipe, remove the spark plugs and turn it over with the starter. Now drain the oil, replace the plugs and try starting without the exhaust - on land - briefly. Now check the oil again. Water can only be coming from the intake or the exhaust so just keep looking for the source. Mine took quite awhile to clear but now works fine.

Have you tried unhooking the battery and then hooking it back this will reset the computer to default settings for the fuel injection, could fix your problem.

Air vents for the fuel and oil tanks.

Well, you are welcome, but I did nothing to make that happen! I suggest you sell that old piece of junk and get a new machine!

Hello Lisa, The most likely fix is for you to check the wires connected to the engine block and verify that they are not broken. There is 1 wire that connects to the engine block then goes to the key, then from the key to the ignition coil block. When the key is in the "on" position the switch is actually open allowing the engine to run. When the switch is in the "off" position it is actually closed and shorting out the ignition block and killing the spark generation, therefore shutting down the engine. So with a broken wire the engine will not shut down at all!!

have you checked the intercooler isnt leaking water into the air intake while running ?

take it back to dealer ss warranty !!

key faulty , get dealer to recode it or replace it !

Pull the plugs and fill it with wd-40.
And whatever you remove just replace tightly.
Unless its a head gasket or gasket mated part, torque values aren't that critical . Too loose and they'll vibrate out. Too tight and you'll snap or strip it out. A lot of repairs at shops are seldom torqued it all goes by feeling and for the stuff that needs to be torqued like internal parts just google whatever part it is and the type of ski and it'll show in your search.

Question, if it is a question not a statement, is way to ambiguous for a decent answer. Much more info needed. The answer to this would be to simply remove the rope.

carburetta main jet

carbs need cleaning and check the pulse jet that squirts fuel on set off , fuel pump diaphrams ok ?

see what volts are there with a multi meter ! if showing 10, 12v then get the battery drop tested with special tester to check all the battery cells dont bubble up as this says battery is duff ! is your charger ok ?

fuel mixing issue. A good tune up is recommended. Focus on the carburetor.

mite need a key post or the key re coding !

check intercooler isnt leaking water into the intake and check the supercharger washers ! remove it and see if the cog slips between the washers , if they have not been changed to the new type then do this anyway as the old type break up and then the engine has to be stripped !!

po544 code is exhaust gas temp sensor functional problem ! is this in the water or on the hose pipe as hose water pressure may be low ? you can only run seadoos for 3min out of water on a hose pipe as the engine cooling system will overheat !

Starter clutch

You can't run those for for than 30 seconds because your not injecting any water thru the exhaust.
