 | I have a 1984 Mercury 200 Black Max that may need a rebuild. I think it may be seized up. Does anybody know what i may be looking at for $$$ damages? Any recommendations for where in S.E. Wisconsin to take it? 
 Thanks

 | It will all depend on what's wrong and what it needs as far as parts.  Could easily be a couple grand.  Could be that it's just not worth it, and a replacement would be in order. 
 A routine rebuild for a high time engine usually isn't brutal, but still costly.  A rebuild due to damage or seisure can get bad because you start looking at new pistons, heads, rods, whatever...depending on actual damage.

 | Without tearing the motor apart and having a costly diagnosis is there a way I could tell I ned a new powerhead or a rebuild? Anybody out there do these things as side jobs? 
 Thanks,

 | If it's seized you'll know it.   It usually won't turn, or if it does it'll grind. 
 I'd look for a used powerhead or a used motor to replace it.  A mid 80's Black Max isn't worth much to begin with so I wouldn't sink too much money into it.  You can find used motors on www.bassboatcentral.com fairly reasonable sometimes.

 | No way to tell real easily if the powerhead is shot.  But you're likely better off with a new motor.  Rebuild will run you $350-$500 per cylinder. |

 | Don't bother rebuilding it, your Mercury dealer can sell you a factory rebuilt powerhead with a warranty! The change -over takes about 2.5 hours and is far less costly than a complete repower or rebuild. I have done several of these and all were happy, in the end. |
