Can some one give me a best guess. We overheated this motor last year one of the coolant tube broke, between the head and front cover they are plastic. We replaced them and the engine run fine at the dock no overpressure and no smoke. We left the dock started running the motor up herd a low tone pop looked back and was blowing white smoke not bad but enough to notice, smelled anti freeze and looked it was coming out the overflow tube at the surge tank. Back off the thottle and the white smoke really blowing. Can someone give some idea if this is a head gasket or an intercooler problem?
Thanks
