Do the plugs have spark (ground on head and have someone turn over motor), is the primer ball firm? Can you start motor while pumping primer ball, Is the ground wire from battery securely bolted down at its' attachment on motor?

Just some shots in the dark, good luck.

I could think of many things that it could be......but considering it's less than a year in use and still under warranty, I'd take it straight to the nearest dealer.
The amount of time and effort involved could be excessive, why bother if it not something obvious that you've already checked?

thanks for the help guys i know the motor is under warantee but the shop is booked till the end of the month and i want to get back on the tuna grounds...i have spark at the plugs i tried to turn the motor over when pumping the ball thant did not work and also the grond wire is snug tight it will just turn over and that is it i would think if i had water in the tank the other motor would of done the same thing..if any of you guys could come up with some other things to try pleas throw them my way i would greatly appreiciate it and thanks for the help so far..
