Need opinions

[Mike in S Fla]

Tried to start my starboard engine after about a 2 month interval and discovered that its seized
I attempted to bar it over with a 3 ft pipe wrench but its locked solid.
I ran the boat in may after servicing the intercoolers for a out of water survey and all was fine
The only thing i could think of is that one of the intercoolers developed a leak and ran down in the cylinders after
shutdown . Im thinking my next step is pulling off the airbox covers and spraying the cylinders with wd-40
and letting them soak. Any suggetions would be appreciated
Thanks, Mike

Pull the injectors and see if there is in fact water, oil or fuel in a cylinder. Don't use the starter again until you find the problem Hand barring only.
