1350 Bites the dust in the driveway

[Tom Smyth]

So I pulled out my Magnum tunnel with the 1350 yesterday and fired it up this Am for a check over prior to running it this weekend. Fired right up, good pee stream, idled perfectly. Oil at 40 to 1 as always. Revved it TWICE to 3000RPM and it immediately tossed the #1 rod through the block. Looks like it broke in the beam as I can still feel the rod end on the crank. This motor has run perfectly for several years at max rpm of 6200. Last time it ran perfectly before I put it away. Odd timing I guess for a rod beam to break, not even under load?

well now I got an excuse to put the 1973 1500 on the tunnel I guess. Will post pics once I get it off the boat. Your thoughts on the failure mode?

thanks

Dam Tom that sucks i know my dad has been crying ever since his 1971 135 overheated the worst part was someone took the boat for a joyride and bought it back smoking my dad still is pissed best motor he ever had

Free revving an engine puts more pulling force on a rod than when you have a load on the crankshaft. Rods don't like being pulled on, as you have found out. It was probably already fractured, just happened to let loose at that moment. At least you weren't out in the middle of the IRL or something when it went.

Sorry man, hopefully you can find a donor or save her.
