01 gp1200r questions

[01gp1200r]

Hey guys. I just bought a 01 gp1200r. with 133hrs on it.. It ran great all day fri and sat. 55-60mph.. Last night i took my water hose and filled half the ski with fresh water to rinse the salt off... We tried to go out today and when we got to the ramp it would'nt start.. would'nt even turn over.. so we yanked it back out the water and pulled the plugs. Water just shot out ruffly 3ft in the air... We brought it back to the house. and took us about 1.5hrs with no plugs in it and shot all the water out.. We finely got it to start and run again.. We took it back down to the ramp started it up. (started on the second turn over)Idled out the channel into the ICW eased on the throttle started picking up. as soon as it got onto plane it died. tried to start it and would'nt even turn over.. Swam it back 300yards to the docks pulled it back out the water.. pulled the plugs and bone dry.. but it still wont start or even sputter... I am sorry to ramble on but i just wanted to give full detail on what i did and what the ski did.. PLEASE HELP

Re: 01 gp1200r questions

how high up exactly did you fill it, in comparison to the engine? You might have got water in the magento or in the electrical box which would cause an issue obviously.

Re: 01 gp1200r questions

about where the case meets the jugs..

Re: 01 gp1200r questions

yeah, that's really bad. remove the mageneto cover in the front of the ski...i bet there is water in there. not sure where the electrical box is on that ski, but remove the cover to that and see if any water comes out.

the best way to clean out the inside of the hull is to put a little water in there...maximum level at the bottom of the case. put a little soap in there and drive to the boat ramp and let it out before you launch it. Get a anti-corrosion spray and spray down the engine when it's hot after you shut it down, that'll help prevent and effects from any salt water that might have gotten into your hull.

Re: 01 gp1200r questions

the cdi is right at the top no where near the water... again i just plugged it filled it. than drained it. I propped the ski straight up over tight to empty it.. the next day nothing.. again the cylinders were full of water.. after we got allt he water out.. it started right up and ran.. just once i full throttled it it died and has'nt started since.. I would think if there was water in the magneto it would not have started .. would it have??? I have spark it turns over... I just think the carbs are jellyied up like the plugs.. Do you think it may just be that simple?

Re: 01 gp1200r questions

I just tried to poor alittle mixed fuel into the cylinders and tried starting it again. and no sputter... does the cat have to be hooked up. for it to even start?? I pulled the cat off and unplugged the sensors to get ready to pull the carbs..

Man it looks like you have to pull the motor just too get the carbs off

Re: 01 gp1200r questions

have you checked your compression?

Three things are needed for your engine to run, compression, spark, and fuel. If you poured fuel into the spark plug holes and it wouldn't start, then fuel isn't the issue. If you do a compression test and it's good, than your issue is spark.

Have you replaced the spark plugs since you saw they were jellyied up?

Re: 01 gp1200r questions

I have not replaced them only sanded them and cleaned them.. I am getting spark threw the wires. I did pour alittle fuel in the holes. I am charging the battery right now with a trickle charger. Ok now check this out. on Sat when you started it up being cold, I would have to granny into the throttle otherwise it would cut off.. then i figured out i could choke it for a few minutes than granny into the throttle than it would just take off and i could unchoke it. it would top out about 54-55mph. I think one time i got to 63mph..... My Yamaha compression tester just came in today. But isnt there a special way to test them??

Re: 01 gp1200r questions

Ok so this is where I'm at.. I have the cat pipe off( the whole "s") But i have the 2 sensors plugged in. I spray alittle bit of carb cleaner into the fuel filter hose leading to the carbs. have the battery some what charged. Sprayed alittle carb cleaner into the airbox. tried to start it and it fired up. ran for about 2 sec. and died... I can not let it run but a few seconds. When i bought the ski. The guy did not give me the hose adapter. and none of the local shops have them. so what i do is just hold the hose to the grate. and try to start it. ( takes 2 people) So it IS a fuel issue. not a carb issue... Any ideas?

Re: 01 gp1200r questions

compression testor should just screw into the spark plug holes and then crank it (with a strong battery) until the needle stops moving. Hope you didn't have to spend a fortune on a Yamaha compression testor...a craftsman from Sears works just great.

I'm not very familiar with your ski and the whole cat pipe, etc, but by putting carb cleaner into the airbox, you're doing pretty much the same thing you would be if you were to put fuel in the cylinders, which is priming the engine by putting fuel directly into the intake. Doesn't mean that the fuel is properly getting through the carbs into the engine when you try to start it and run it normally.

PS...don't use carb cleaner, it's very dangerous and doesn't provide any lubricant. The best thing to do is a teaspoon full of premixed (40:1 ratio) fuel into each cylinder.

Re: 01 gp1200r questions

I was told there was special way you had to do it with a pwc..

Re: 01 gp1200r questions

nah, I own 4 of them. Every year when I take them out of storage to get them ready for the season that's how I get them started so I don't put excessive wear cranking the starter. Works like a charm.

I got your PM...I can give you a call tomorrow after work.

Re: 01 gp1200r questions

ok cool.. well It fires up when i put fuel in the cylinders.. I am going to let the battery charge over night. and go try to find the adapter tomorrow. and see if it will start on its own.. The battery is just about dead and i am hoping it was to dead when i tried to check the compression.. **** 1 was 75. one was 76. and the last one was 50. but the battery went down at the end... I will try again tomorrow when its charged and i have the adapter..

I emptied the fuel filter before i tried to start it. and when it fired up than died i checked the filter and it was full. go the pump is working.

Re: 01 gp1200r questions

LISTEN UP! You MUST start the engine BEFORE turning the water on...AND you MUST turn the water OFF before turning off the engine.

If not done properly, you'll fill the engine full of water!!!

You can start the motor dry and run it for 20-25 seconds. There is no rubber impeller to fail like an outboard.

The only limiting factor is the motor gets hot. You can feel the head/side of jugs to get an idea of temp.

1st and foremost get a compression test done. You must ground the plug wires to avoid blowing the CDI and hold the throttle wide open. NO garden hose involved!

To avoid grounding the wires, just hold the stop button (red) down, while you push the green start button.

Report back.

Re: 01 gp1200r questions

But with no water. doesn't the prop shaft bearing take a *****?... I Got it running on the hose now. but it wont idle for more than maybe 30 sec. If i mash the throttle it sounds like its being choked out... how do you know when the shaft bearing is done?

I just tried to flat out start it this morning and nothing.. I'm gonna let the battery charge back up and try fuel in the plugs.

Re: 01 gp1200r questions

105 105 95

Re: 01 gp1200r questions

Those numbers are low. I believe you should be getting at least 120. It could be that your compression guage is not calibrated properly. The reason I say that is becuase the numbers are so close together. If you can, try a different guage and see what you get.

 

[01gp1200r]

Re: 01 gp1200r questions

I still just think its my carbs... if i pour fuel into the cylinders. and spray just alittle carb cleaner into the air box it will start right now. and run for about 30sec. than die. but i can keep starting it and it will run. just wont idle... But if i let it sit for an hour or so. then I am back at square one..

 

[bigdaddypt]

Re: 01 gp1200r questions

you're probably right...those numbers are low, but it sounds like it's the guage calibration.

You have to remove the carbs and they need a full rebuild with new needles and seats too (don't come in the carb rebuild kit). It's also a good ideal to blow out your fuel lines to make sure they're not gummed up at all, and clean the fuel selector valve and replace the fuel water seperator.

Are you capable of doing this?

Rebuild time for sure. If you filled it with water the carbs sucked it in as they are on the side. I am sure there is still water in the carbs and the only way to do it (right) is to take them off and rebuild them. I am sure that will solve your problem. You never want to start it with the water on as stated earlier. Start it first them turn on the water and before you shut it down turn the water off.
