🔌 Function

Transmits drive through the gearcase, taking engine torque and delivering it to the propeller shaft at the ratio and direction the drive is built for.

⚠️ Common Signs of Failure

• Whining, growling or rumbling from the drive that follows engine speed or load and worsens under thrust
• Water in the gear oil — a milky or grey sample — or persistent oil loss with no obvious external leak
• Oil weeping from a housing joint or seal face that returns after new seals have been fitted
• Visible cracking, impact damage or heavy corrosion of the casting, typically after a grounding or a strike
• Roughness, notchiness or play felt when the drive is turned by hand

🛠️ Service Notes

• A gear housing is a machined case that fixes the position of the shafts and bearings inside it — treat the bearing seats and mating faces as precision surfaces and never dress them with an abrasive, a file or a scraper
• Shim thickness, bearing preload and gear backlash belong to the housing, so they must be re-measured and re-established with the correct measuring tools when a housing is renewed rather than carried over from the old one
• Fit new seals, O-rings and gaskets throughout, and check that oil galleries and any breather or drain passages in the new housing are clear before assembly
• Assemble clean and lubricated with the correct gear oil, tighten the fasteners in the manual's sequence and to its figures, then turn the drive by hand to confirm the gears run freely
• Pressure and vacuum test the assembled drive for leaks before launch, and check the oil level and condition again after the first run
