94 sp help!

[Waterboy87]

I have a 1994 seadoo sp and the fuel seems to be making it to the carb, however it wont start. when i spray starter fluid in it, it will start but it seems like the fuel isn't making it in to continue the engine running. any ideas or any help????

Welcome to the seadoo forum. It is possible that the carbs are dirty and not allow fuel to go into the carbs to the engine. You shouldn't use starting fluid as it has no lubrication value and could cause more problems. If you need to take some oil you use in the seadoo now and add a small amount of gas to it to make a pre mix. Add a few oz of the pre mix in the spark plug holes and that will be better to get it running after you find out if the carbs are the cause of the problem.

Yes!!! dont use starter fluid anymore!!!!! Its has no oil in it and it will dry out your cylinders and cause damage. Take of the hose to the carb and if you have a brake vacuum pump hook that up and see if anything comes out. If not then take the other side of the line off the filter and connect directly to the Reserve line on the tank then try to start. This will bypass your selector switch which can be clogged. Also there is a little filter in the carb that can be plugged. Good luck

I have taken the hoses off and I am getting gas to the carb however it doesn't seem to be making it into the carb. Is there a specific way to clean out the carb, season is almost over and I need this thing running!

If your careful, you can pull the carbs off and tear them apart without damaging the diaphragms and gaskets. Pay special attention to the internal filters, as they are the usually clogged with gunk. Use Spray carb cleaner to clean all the passages too. If the seadoo has the gray fuel lines that is what might have caused the problem in the first place. If so replace them also. Go to like Auto Zone and get the proper size as a replacement. You might need about 18' f the clamps are bad replace them too, with stainless steel ones. The old gray fuel lies deteriate from the inside out and clog the carburators.

Let us know if you get in a jam and need more advise.
We have a Seadoo manual to help you out in the "Premium Members" section.

Does anybody know where I would be able to find a walk through on taking the carb off, of a diagram to just give me an idea of what I am doing. I haven't really had much time under the hood (or seat) of a seadoo and would hate to do more harm then good... any help would be appreciated.

unfortunetly, only way to get at them, is to undo the 4-13mm hex bolts, hold'n the rv cover/intake manifold on, then with ease, remove the cover, but pay attention to the rv plate, so it dont stick to the manifold, and mess up your timing.

 

[Waterboy87]

I can only seem to access three of the bolts, the fourth is behind crap. any hints or easier way then taking this entire engine apart?

 

[Waterboy87]

I was able to get the carb off and I cleaned it out and man there was some gunk in it. I put it all back together and back on, but it still wont start... I know I am getting annoying but please help...

I just went thru this identical situation. So take your time and do this right. Go get 25' of 1/4 fuel line and a bunch of galvenized 1/4 clamps. Replace one fuel line at a time (I am slow that way!). There is a twist off fuel filter just above the fuel tank. Be careful and twist counter-clockwise and pull down at the same time. If it is too garbaged up, disconnect (one nut) and move it to where you can "persuade" it a little better. You can get a replacement by accessing the parts link on this web site (RivaMotorSports.com) is ultimately the supplier, but you get good discounts using this web as the doorway. Next, replace your fuel selector, some people "blow them out", I wasn't so lucky, I just replaced it. Now this is was the scary part for me, replace the carb fuel filter(s). Sorry don't know if you have one or two carbs, with Premium Membership here you can hit the service manuals or they are on other websites also. Order the right amount of small fuel filters for the carb(s) you have. REPLACE THEM!!! It took me about 1.5 hours to do this cause I usually stab myself with a screw driver! (Hint: clear your work area, lay out some white rags and use that as your carb filter replacement area...that way you won't lose parts and you can "group them" as you take them apart. Yes you have to take off a far amount of stuff to get the carb(s) out, take your time, it is easier than it looks. You will have to disconnect a cable or two, throttle and ???. Again take your time. I did all this in the last two weekends, I also did a bunch of other stuff. Replace your plugs too. The one thing I didn't do that I wished I had was pull the fuel baffle off the top of the fuel tank, siphon the gas out and clean the tank.....maybe this fall when the water reaches 44 degrees. So that should get you back in good sted to ride the rest of the season however long it maybe. Fuel filters are not hard to come by and carb rebuild kits are available (if you are really a masochist) are available from sbtontheweb.com
My ski soars after barely operating, just like you described.

Good luck!
