Engine blocked

[isailor]

At the end of last season I made a light preparation for the winter on my tender outboard, Johnson 3.5 hp (new), and kept it at home. Today I tried to start it up and surprisingly the engine didn´t rotate. Apparently the piston is stuck.<br />Anything I can do?<br />Thanks for any help.

I know this sounds stupid, but check that he starter isn't stuck. If it isn't, you got a problem.

Thanks for your answer.<br />I took out the spark plug and confirmed the piston is stuck. Everything else is ok.

Re: Engine blocked

Try squirting some two cycle oil in the plug hole and get a wrench on the crank and see if it will break loose.Is it stuck at top ,center , or bottom of stroke?

With WD40 and the wrench tool slowly it eased and is now working ... perfectly!<br />Thanks for your help !!!
