    2005 Seadoo RXP Starting issue

    HI,

    My Names Nick,

    I've read a couple posts similar in nature but not directly addressing my issue so I apologize in advance if I've not come across the answer to thsi question already.

    Last year I bought this 05 rxp and it was in great shape, had a few minor upgrades that were weak links in the system. I'm fairly new to the PWC world so I brought it to a seadoo dealer just to confirm all is well and it was.

    I ran it with no issues what so ever through salt and fresh water flushing and thoroughly washing it in and out after each day out. it has ~95 total hours on it.

    I had it winterized and all seemed to be done correctly, they fogged it put the antifreeze in took the battery out wrapped it etc.

    This year I had to buy a new battery, installed it and fired right up with the flush kit on it. I ran it till the smoke cleared. Shut it down waited for it to cool started it again and ran for 5-10 mins checking the oil frequently.

    Today I was tinkering with the trailer wiring and went to fire it up and you hear the fuel pump and everything the gauges go per normal but when you hit start you here a loud click/thud and nothing turns over.

    I read that it could be the batter CCA but when I hooked cables up to it the same thing happens.

    I don't want to dive in too deep without some guidance here, i know my way around an engine pretty well but being marine i figured i should just seek out some better knowledge.

    Could this be that the bearing in the starter are seized? Worse the engine? is there another step before i bring it to the dealer (who has a questionable service reputation anyways?)

    Thank-you

    Nick, what does the spark plug at the rear of the ski look like?

    1. Don't use jumper cables. Can cause more problems. Verify battery properly charged. Check solenoid.

    Why are you running it so long, even on the hose?

    When you're turning the engine off, are you shutting the hose off first? And are you starting the engine first before turning the hose on?

    If you can get hold of a workshop manual there is a series of diagnostic tests to perform to determine if the starter solenoid has failed. The one I used to determine my solenoid had failed was measure the voltage across the 2 terminals of the solenoid while hitting the start button with the engine in drown mode (holding WOT), the voltage across the 2 terminals should be less than 0.2 volts.

    I would try that first. Do you know how to bypass the starter solenoid with a screw driver?
    Oh, and welcome to Greenhulk.

    don't be jumping the starter solenoid on a 4-tec..wayyyy to close to the fuel tank for those kind of games

    starter solenoids ( the old style) are such a large fail item I keep a bunch of them in stock.

    the newer style ( fully molded) prevents water intrusion and should last a real long time.


    take advise in post #6
