Re: My humble request for admission to the Starmada: 1972 21' Chieftain OB
Good luck with the "Tower of Power" Mercury. They are good engines, I am running a 1972 1150. The engine wiring harness will be super brittle if it hasn't already been replaced. Search "waking up an outboard" for some direction in getting the old girl running again. You will also want to replace the fuel lines and do an impeller and drain and check lower unit for water intrusion. I also just had a fella up in Illinois totally rewire my Mercontrol remote with new ignition switch, battery cables and all new internal wiring. So crack that thing open too and see what it looks like inside...probably the same brittle wires. I can get you his number if that is a route you consider taking. Here is a pic from a running 1150 for reference. The Merc forums here on iboats are a great resource too. They will tell you to first check compression before dumping any money into the engine.
Let me know how the engine works out for you. And let me know if you decide to repower and we can see what you need for me to take it off your hands. But don't give up on that old thing...you will be hooked on these old inlines as soon as you hear it fire up!
Sorry for treating you like a rook...I just noticed you have more posts than I do. So I probably didn't tell you anything you don't already know. But if you have any questions I will try to answer them.
