Please advise what to look for when buying a used Mercury OB. The engine is a Thunderbold 80HP, around '79.<br /><br />Can I do some tests myself, or do I have to let it be checked out by a dealer?<br /><br />What are weak spots?<br /><br />thanks.

uhehn<br /><br /> Do a search on this site alot of good info on buying a used motor. At the very least do a compression check and take the motor in the water and test under load.
