    Broke powerhead bolt

    It looks like you are pointing at a Cylinder Head Bolt. If that is the case, then you must replace it. If you are pointing at some other bolt, provide a better Pic, even if you have to wait till the rain quits

    1977 Baja on the cheap

    That Starting Fluid certainly didn't do the engine any damn Good. I guess you could buy it, and might get a bit more for it by Parting it out. It is 46 yrs old, and will probably new all new Wiring on the Engine, and a new Wiring Harness. Compression is unknown... I suspect the Transom is...

    Not good. Maybe

    For 20 yrs, I have just drained the Block, the manifolds, the Big Hose between the Circulating Pump and the Stat Housing, pulled the Ignition Lanyard and cranked the engine to allow the Raw Water Pump to drain any water out of it and the Passages.

    72 Mercury 500 No Spark

    All the Seals on the Drive Shaft are in the Lower Pump housing. There are a couple more Seals on the Prop Shaft, that are in the Bearing Carrier, and there is an O-ring on the Bearing Carrier.

    72 Mercury 500 No Spark

    You will know if water is getting in when you drain the Oil. Of course, if you just bought the unit, a sharp and unethical seller, could always drain a Unit, then refill it with fresh oil, and that would hide any leaks, till after you use it. Best to get the Unit, Pressure and Vacuum tested

    You are right, the 84 was the 3 cylinder Merc. I saw 83 on the back of a Brochure, but that was the copyright date, for 84 Brochure. The 83(copyrighted 82) brochure does show a Twin of Foreign Make. Good Catch.
