Learned the hard way that on a MEFI 3 system, when you are on the limiter trying to win a race 
, it pulls fuel back, not spark. 2 pistons were fried. Literally. Looked like they had been cut with a plasma cutter. Oooopsie.

Mine had a small backfire at first startup of the season about ten years ago, was going to a Good Friday Crawfish boil about 4 miles down the river. What I didn't know was that it blew a rubber plug off one of the small ports on the carb base plate. About half a mile into a 3000rpm cruise down the river it blowtorched a hole through number 2 piston.
Never saw the missing plug until I was putting engine back in boat. That was the moment I realized we had reduced the compression from 10.4 to 9.8 and timing for nothing!!!!!!!!! Son of a bittch.

Which time?
When we were drag racing it wasn't an uncommon to "wound" a motor. The button to arm the NOS was labeled "shark" because it eats everything. We were burning the spark plugs down every pass. I have an oil pan hanging in my pole barn that looks like someone shot it with a 12 gauge & it has a piece of the block still attached to it. We did that in Guelph, Ont. back in 2000 if I remember correctly. That was a great venue. I believe we were the only powerboats allowed on the water all year because it was a protected site of some sort.
