One of our customers sent this 3.0 liter Merc powerhead to us for a rebuild. Upon opening the crate, we see that it has a label on it that shows it was factory remanufactured by Mercury Marine (Quicksilver Remanufacturing).
We removed the powerhead from the crate and disassembled the block. What we saw next was one of those scenarios that just sickens your stomach. The crankshaft in this $5,000.00 factory reman powerhead from Mercury Marine was broken completely in two.
It didn't take much inspection to see that the crankshaft Merc put in the powerhead was already cracked about 3/4 of the way through the rod journal when installed. Rather amazing the motor ran as long as it did. Really bad part, it was just out of warranty, and Merc wouldn't touch it. Shame on you Mercury Marine! It's fairly typical for Merc to make excuses, unfortunately.
Had this powerhead been rebuilt by TMS, the warranty would have covered the entire repair. But for your information, we don't make a habit of installing "pre-cracked" cranks in our rebuilds in the first place!
Ok, I'm convinced! What do I need to do?
