Why do want to disable your other engine to get a gearcase for the engine you are working on? The 56 30hp gearcase will surely fit on your 57 35hp.
There are the seven bolts that secure the gearcase in place, but first you must disconnect the shift rod. The shift rod connector is hidden behind a small oval cover in the middle of the exhaust housing on the right side of the engine.

Hello Fleetwin,

I don’t know of any other option but to find an operable lower unite (gear case) and just replace the broken unit on my Evinrude. Simply unbolt the Johnson as an example, and bolt the Johnson onto the Evinrude Big Twin. (And have my mechanics test pressure, replace seals, etc. at the same time.)

As I have learned from the nice folks posting here, my tail fin piece that is cracked and the above housing are machined at the same time, so I need to just go ahead and replace the whole thing.

I’m working with a fellow that has a lower for a 1957 Evinrude Big Twin 35hp that would be an exact match for me, and apparently the gears are all in good working order and clean, etc..

I guess I just don’t understand exactly what other options I might have. If you could clarify, I would certainly appreciate.

Thanks!
