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 !

check hull type as a freshwater hull and a sea hull are different as sea water has a higher level of buoncy .Although i doubt if you will encounter a freshwater hull but it is a thing to think about and check.Main cause though could be lack of engine power for whater reason .

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.

does this happen repeatedly or just sometimes? check the one way vale and the line its attached too on top of the fuel tank then make sure theres no water in the fuel filter, if there is water in the filter it should be visible and kind of look like a bottle of salad dressing or oil and vinegar before its been shaking up.
