Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.White smoke in most cases means the engine is ingesting coolant. I would start first with running a cooling system pressure test to see if the system will hold pressure. I would also perform and engine block test checking to see if the head gasket are possibly leaking. This test will check for any signs of hydro-carbons in the cooling system. If these checks okay then the next steps would be to run a fuel pressure test to see if the fuel pressure is holding steady. Check these things for me and post back with the results and we can work from there.
