    Hi all, I have a '53 Evinrude Lightwin 3hp. Starter rope looks like it's as old as the motor.

I'm just not sure exactly how the end of the rope is mounted...

    Hey all, So I'm not REALLY experienced with gearcase resealing, this is only my second one I've had to complete.

It was stuttering pretty good. Based on the fact...

    1960 Fastwin Gearcase Reseal

    Last year I was able to get myself a 1960 Evinrude Fastwin 15033. For some reason I really like the looks of these 1960s. Very representative of that era of time I feel. Anyways, I've been working on outboards for the past few years but this is the first one I've gotten one that hasn't held...

    Outboard Detailing

    Curious to find out how everyone details their outboards. I have a few vintage evinrudes that could use a good degreasing (including under the Cowling). How does everyone do this? Process? Products? Cheers, JG

I did some quick searches and seems as though...
