Can anyone tell me the approximate value of a Baldridge reverse gear? I believe it was used in marine applications...I found this site and figured it was the best place to ask. It's in nice shape. All enclosed. I can get a picture if that helps.
Thanks
Caleb

Hello, Caleb

in N. San Diego County, CA
I'm assembling a 14' Geo Lawley skiff
with a 6hp Roberts 2cyl two cycle engine
and am looking for a small reverse gear.
Is yours still available?

I don't have a gear like this but it looks like it would be easy to fabricate. The band looks to be in the applied position right now, if moved back the band should release. Get a piece of 5/8" cold rolled steel cut to fit between the band levers, drilled for the bolt, appears to be about 5/16". With the shift lever in the neutral position fit two plates drilled for a bolt through the shift lever hole, weld them to the cold rolled. When the shift lever is moved it will link it to the reverse levers. It looks like the bolt through the band has to be tightened some to apply the band fully. The gear should lock in forward, generally had to be held in reverse.

Hi
I agree it should not be to hard to make. But would be nice to see how it should look like

Why is there drilled a hole in the top lid?

I wondered that myself! My first guess would be that over time it developed oil leaks around the main bearings which if I remember correctly are poured babbit, and rather than repour the bearings Mr. Boater decided to keep adding oil! But, there is already a hole in the top cover with a pipe plug in it, so my next thought would be that with further wear something in the gear began to "stick" and so Mr. Boater made that hole to insert a bar or lever and "help" the gear to shift! Messrs. Baldridge didn't provide a filler hole, probably to encourage the idea that their fancy new "fully enclosed" gear required little if any attention from the user!

PS: if you go back and edit your first post by using the "return/Enter" key after each photo name, your post will be much less wide, and so will every post after it!

Does anyone have a usable Baldridge transmission for sale. My husband has a 14' boat and a 6hp engine, but no transmission. Says he "wants a Baldridge.

I bought myself a Baldridge reverse gearbox no 6 to put in a small boat. I don't have any specs about the gearbox. Does anyone know if there is a prescribed direction? Left or right? A manual would be great.

The old type of F-N-R gearboxes will work OK in either direction.

I've seen people use the reverse to go forward because they could not get a prop with the right rotation for their engine.

Please DO NOT do this!

In the FORWARD direction of the gearbox the insides of the gearbox are turning as a single unit.
When the reverse is engages, there is rotation of the gears one against another. That's why the reverse is noisier than FORWARD plus there is more wear on the gears inside the gearbox.

Miro thanks. Some other questions: What kind of oil and how much?
Somebody familiar with repairing the babbit bearings?
