    quote Bill Austin:

    I removed the lower unit this afternoon and it was free and turned over easily. There was not any water in the lower unit gear case. I’ve got Kroil soaking in the cylinders and I fully suspect that I will just have to be patient and let the Kroil do it’s job.

    What they were saying is if the motor turns with the lower unit removed the pistons are not stuck. Kroil is not the solution for this case. Sounds like something in the lower unit is stuck.

    I took this to mean the lower unit was free, not the powerhead – like you can spin the driveshaft once it was pulled with the lower. Bill – please clarify.
