Re: 1957 Evinrude Big Twin-Frozen Flywheel-UPDATE

quote danblue:

But wouldn’t the 1957 Evinrude/Johnson powerheads have these faulty wrist pin needle bearings…even if the powerhead on my Big Twin had been rebuilt at some point? Fleetwin recommended I look for a 1958 35hp powerhead since the manufacturers used a more reliable bearing for the wrist pin after all the problems with the 1957 models.

Is this correct guys? Shouldn’t I look for a 1958 35hp Johnson or Evinrude powerhead?

BTW, I just checked and the serial numbers on the engine plate match the serial numbers on that little round silver badge on top of the powerhead, so this is the original powerhead on my Big Twin and I would imagine it was never rebuilt!

Thanks,

Well if the ’58 has improved needle bearings, then I would go for that. Dont worry though, the ’57’s are still good motors though. The needle bearing issue is not really that common. Look how many ’57’s are still out there. LOL
