"Hi guys, I have been an avid reader on this forum for some time now but today I decided to join. I have had an ongoing problem with my boat last year and I am going to attempt to fix it this year. I have a 1983 merc. 485 with an enclosed cooling system. Anyway the problem I am having is the boat will start and run great when cold, then after I shut it off for about an hour and go to restart it it takes a very long time to start and it smokes for about 10 seconds then it's fine. The smoke is anti freeze and my level goes down but very slow. I was going to take the head off and have a look at it but I figured someone might have had this before. Three years ago I rebuilt the engine. I put new crank and conecting rod bearings,piston rings and all new gaskets. The only thing I noticed was a small crack internal to the exhaust manifold. I could not find a manifold at the time so I just reinstalled it. It wasn't burning the coolent it burns now. It has gotten worse every year. Any help would be greatly appreciated. Thanks. Scott"
