Rebuild Pictures


Well, I finally have the new transmission for the HollyB.

A Twin Disc MG-509 with a 1.454:1 Gear Ratio...Real close to the original 1.5:1 ratio.

All rebuilt and ready to go in thanks to my mechanic, Mike Doherty and Mario from Marine Engine Service.  Two top guys in the marine diesel engine trade in the Los Angeles Harbor area.

The original transmission was an old crash box, manual shift, and over 60 years old.

It was shifted with about 50' of 3/4" galvanized pipe controlling it, and a lot of muscle.

The new one is hydraulic and just takes a simple MorseControl cable.

Finally .... Easy Shifting !!
