Blown outboard prop shaft seal?
You probably know this already but when you store your outboard for the winter or any period that is might be in less than 32f remove the prop and make sure (by tilting it) that all the residual water gets out of the torpedo/prop shaft area as ice can damage the seal. i doubt your transportation method damaged it. Get the service manual for the engine wether you fix it or have it done by a shop so you know whats involved to R&R it. Good Luck
