Overview

Marine gearboxes and transmissions transfer engine power to the propeller, provide reduction ratios, and enable forward, neutral and reverse functions. They include reduction gears, clutches, shaft couplings and mounting flanges built to handle torque, shaft alignment and marine corrosion. Buyers select units by matching engine RPM and torque, input/output spline sizes, ratio, mounting pattern and condition—new, rebuilt or OEM—plus spare-parts availability for the vessel.

FAQ

What should I check when buying a used marine gearbox?

Verify model and serial numbers, gear ratio, input/output spline count and diameters, mounting/flange pattern, signs of corrosion or water ingress, oil condition, backlash/play, service history and whether seals or bearings were replaced.

How should a heavy marine transmission be prepared and shipped?

Drain fluids, secure or cap openings to prevent contamination, block and brace on a skid, protect against salt and moisture, use certified lifting points, choose an experienced heavy-equipment carrier and insure the shipment.

What routine maintenance is vital for marine gearboxes?

Change gearbox oil at manufacturer intervals, inspect seals and bellows, check coupling alignment and shaft runout, monitor for unusual noise or vibration, replace sacrificial anodes if present, and log operating hours and service actions.
