motor wont crank

[mikel67]

my 50 hp tohatsu outboard stopped running while on the water. it was running fine (although never really got up to full speed) and then slowed down until it stopped completely. i can not pull the starter cord (engine is in neutral prop spins freely. please help. do i have a seized motor?? motor has been stored (winterized)for 1 1/2 years before this problem.

thanks

Re: motor wont crank

It could be seized, or the neutral lock could be engaged. If an old 2-smoke premix model (what model is it?), I hope you were running 50-to-1 fuel, and not straight gas.

Re: motor wont crank

thanks for the reply. the motor is a 2007 with 10 hours on it. used 50:1 mix but fuel was old 1 1/2 years old (i did use stablization additive while stored it smelled fine and motor ran ok for about 20 minutes then steadily deteriorated over 5 minutes until it quit entirely. how can i tell if it is seized vs just locked?
