Yamaha jet ski

[arcticman]

Hey guys, visiting a friend in Florida, he has a jet ski that will not stay running after it get warm. I have installed new spark plugs ran great out to the bay and at forty miles an hour it up and died. would not restart for several minutes. This a yamaha xl 1200 don't know the year.Act like the starter is not engaging and when does will only start with choke and 1/2 throttle. Help

Check the compression first. Then check to make sure the choke isn't sticking. Assuming it's not fuel injected. Just my idea's

Check the battery conections. Loose or corroided?

Do all the above,
There is a plethera of things that can be wrong. Very little info to troubleshoot. did it always do this or did it just start? Are you getting good cooling ? Check the pipe it should not be too hot ( sizzling ) . Does it have a pisser and is water coming from it ? Sometines the starter is right next to the pipe on some models. You have to rule out some things , try to jump the starter straight. Sounds that heat is effecting the ski because after it cools it is good ? A good place to ask some questions is PWC Today. There are quite a few knowledgeable people in each forum. Most of my stuff is old school & modified stand-ups. Check out the yamaha forum and do a search. That way you don't have to get activated . A lot depends on how( what words you search for )"like yamaha 1200 gets hot & shuts down". If you can post ( sign up ) and ask for help, you will get some. Hope that helps.
