I have a 1999 yamaha

You must try to crank it by hand ,remove spark plugs so there will be little compression and then try to turn the motor it should turn without to much force this will indicate the motor has not seized when hooking up a jump start do not connect both leads directly to the battery ! the red + lead should connect to the red+ on both batteries but the neg lead - should not go to the battery post but to a ground usually directly to the metal engine cover or you can damage the battery !

Why does yamaha waverunner fx cruiser ho not run in lake but will run hooked to water hose

Sounds like you have a bad stator. It may be producing enough spark to start the motor, but under a load (as in the water) it simply can not supply the amount of spark needed. Sometimes when a stator is tested on a ohms meter it may test good, but still be defective do to the load it will come in contact with when put in the water.

No fuel to carbs waverunner yamaha XL760

I have one as well. Same problem and it got worse until I had to prime the carb to run. Fix is simple. 2 carb kits off eBay. Approx $30 ea new. Takes about 2.5 hours to do. I have never done before so I thought it was easy. What happens is the carbs have rubber diaphragms in them that act as a fuel pump. My old ones were really thin and worn. The new ones thicker and better. Put it back together and viola. It starts on it's own. I checked all forums about shut offs and external primers, pop pressure etc. Just rebuild your carbs. You'll be fine.

Rear seat removal, fx yamaha jet ski, latch will not release the seat

As bad as this sounds its the only way. Grab yourself a 2x4 and a nice size prybar.Lay 2x4 across the back grab handle as to not damage it then put prybar directly under seat latch and pop it up.
