01 150 Ocean Pro Siezed

[joeturse]

Running in the other day it siezed up.No oil or overheat warning at all.At home we pulled the plugs and dumped WD40 down each cylinder to free it up, and got it to turn over.It would start and run(real rough)for a few seconds.
What is your opinion,is the powerhead toast.
