I have a seadoo bombardier gtx 951 I recently had a few problems getting it started from home at the beginning of the year (with hoes pipe connected don’t worry not dry start) I found the problem I had bad fuel and a block in my fuel pipe and fuel filter was covered I managed to get rid of the problem and finally get it started, I took it out to get a good day out of it on the beach but once in the sea it would start on the button first time then once beginning to ride after 3/4 second would cut out on me I wasn’t taking on any water the hull was completely dry I had new spark plugs, new battery , complete new fuel and oil all fuses was changed , after restarting 5-10 time it would no longer start and had to be pulled from the water and can’t find out what it is and now won’t start at all , I really need help as looking to sell and invest into a brand new model and would like to have some money to put towards instead of selling as a non starter and losing a lot of money any advice is helpful thankyou all

Check compression and then rebuild fuel system.

I'd go in this order:

1) check to see if it's a fuel issue. I'd pour a little 2 stroke oil in the plug holes and use some starter fluid in the air intake to try to start it. If it starts, you know it's a fuel issue and I'd rebuild the fuel system. if not, step 2.

2) Check spark and compression. Anything over 120 psi is good, below 120 psi, the lower it is the more definite it is that you need a rebuild. If theres no spark, check your fuses. if its not fuel, not compression and not spark, id go to step 3.

3) Check your rotary valve cover clearance. Higher mile pwc's clearance can get out of spec and the ski will not start. You can use a feeler guage to check the clearance. If it's out of clearance, send it out for servicing.

4) These steps are assuming the engine is spinning freely. Make sure the pump is clear and the engine spins.
