I have a 1999 yamaha waverunner 1200, the battery died so we tried to jump it and now cant get it to crank over?! The display screen comes on and we pushed mode for 10 seconds and then entered code, but it made a weird beeping sound and the said start. When we went to start it wouldnt even try to crank over?? Any soultions?

possible air leak at your cylinder base gasket or a crank seal.

See page 46 of the attached PDF manual (page 2-19) What you are actually seeing is "EXHST" which indicates the exhaust temp is too high. http://www.yamaha-motor.com/assets/service/manuals/2001/lit-18626-04-01_360.pdf

you may have an air leek on carbs or its running too lean

bad earth or wire , clocks only come on when started !

hi there it sounds like the switch gear need pulling apart and the copper contacts cleaned as it sounds like the kill switch is closed up and the starter button contacts need cleaning as well also check to see if the stater soliniod might need a cleanup where the wires go,also check your fuses to see if there contacting alright if you ride in all weather or the bike sits outside it can have these problems as mouisture gets into everything. hope this helps cheers pete

remove all sparkplugs and hold full throttle and crank over several times to get water out of cylinders ! have a jump pack ready as battery will die ! use carb cleaner on the plugs each time you try to run after this , hope this has only just happened as internal damage might already started ! if all ok check the engine oil also as water normally gets in after this problem ! if oil is milky then change oil several times , run for 15min on hose each change until oil normal colour ! then you must take for a run for an hour to help dry it out !

plugs out and crank the water out , put your finger over plug holes as you do this and will help purge water from crank ! Plug caps away from plug holes !! have a battery jump pack ready as will take a while ! if plugs ok then clean with carb/brake cleaner once most water is out then put a sqwert of fuel in each cyl then plugs in hand tight and get cracking coz if left too long crank etc already rusting ! DONT STOP till you got it running as you will have to clean the plugs several times ! Try all three plugs at first then if struggling two plugs and one out with rag over hole and plug cap away safe from plug hole so not to spark fuel !!!! NO SMOKING !!! Fire extinguisher handy !!! once running ON ALL THREE CYL'S , not one or two as you can sieze the engine take to lake and give a good run and making sure all cyls working ! can do this while strapped to trailer in water as long water circulating !

your starter is shot more than likey try to jump the relay in that black boxs buy jumping the two post on that round relay if it does the same its the starter if it turns over its the relay or the start **** becareful jumping the relay no fuel around air bike out and you have to take off the exhaust manifold to get to the starter

Try jumping the waverunner using a set of jumper cables and your vehicle, this will rule out if the battery is bad. If you still have the same issue, check the connections. The connection at the starter or another place may have corroded a bit. Yet another option is to remove your spark plugs to make sure that your motor has not hydraulically locked. Once you have removed the plugs try and turn over the engine. You may need to ground out your plug wires if you have an electronic ignition to protect it. I hope this helps.
