Does reverse running change the gear design?

It changes the duty, not the tooth geometry. The pair runs in both directions, so the drawing has to state the load in each.

Why ground rather than lapped for marine duty?

Continuous duty rewards a profile that stays put. Grinding gives a repeatable finished tooth that does not rely on lapping contact to compensate.

Can you match an existing marine gearbox?

Yes, by measuring the existing pair and the housing. Mounting distance and shaft alignment must be confirmed first.

What about corrosion protection?

The gear is supplied to the drawing; protection and lubrication are agreed with the gearbox builder during review.
