removing the cap is a good idea. if your garage has open trusses, you can ratchet strap the cap to the rafter and raise it out of the way.
you can build a cradle between your trailer frame and hull if you need additional support.
my guess is it wasnt winterized properly.
however you need to drain the water jacket and pressure test it.
you may get lucky and it may only be a failed oil cooler, or its a cracked engine block, cracked heads and cracked exhaust manifolds from failure to winterize. the water jacket pressure...
