5700 RPM on a 250ish hr. 300 Tempest SBC. The boat shuddered for a second then slowed down. No.5 piston hanging out the side of the block, crank came out in 2 pieces, cam came out in several.

Alright - long story, but I'll try to keep it concise.

Bought the boat (w/ Merc HP500s) midsummer 2012 and put 25 hours on it right away. Ran fine, no problem. WOT several times. Once it was in storage for the year, I got a call from some random guy I'd never met. 'Do you own White Knuckles?' he asked. I said yes, and who is this. He would only give me his first name, but no last name. Very sketchy character. He told me that the guy who owned it before me (former friend of his, name was Chris) was a total scam artist and pathological liar. One of the stories this guy told me was that Chris blew the port side engine, patched it up as cheaply and quickly as he could, and sold it to a dealer. He claims that the motor was a giant piece of crap inside. I got a little nervous at first, but ultimately dismissed it considering I had gotten several good hours of it already.

Fast forward to this past August. Flying WOT in Lake Michigan with a buddy when I notice one of the engines running 500-600 RPMs lean. I slow down, that engine cuts. I fire her back up, and blew smoke plumes from the exhaust. Bad news. We get the engine apart a few weeks later and find the cheapest bunch of mismatched parts you've ever seen. It was like whoever put it together just picked whatever parts off the shelf to get it running.

I was just lucky that I got a over 100 hours out of it before the BOOM!
