Nissan 3.5A drivetrain locked

[tpaparsons]

Bought this Nissan 3.5A used a year ago. Put a new sparkplug in it and it started just fine. Didn't run it after that. This year, can't get the piston to turn -- can't get the starter rope to move. Can't rotate the prop.<br />Removed spark plug and sprayed Kano Aerokroil on the cylinder. Replaced spark plug and positioned outboard so oil would remain on the cylinder top. No luck.<br />Removed fuel tank and recoil starter. No lockup in the recoil unit. Still can't move drive train prop.<br />Shall I dig into the lower unit or power head next ?<br />Thanks for hosting this forum -- very useful -- I read all the posts and answers for Nissan/Tohatsu!

Two bolts and a pin holding the lower unit on...Drop it and see which one is bound up. It will probably be the powerhead.
