What could be causing the transmission noise in my Beta Marine BV1903?

If you're experiencing transmission noise in your Beta Marine Engine, consider these potential causes: * **Check gearbox oil level:** Top up the oil level. * **Drive plate rattle at tickover:** Check the engine RPM (must be 850 RPM minimum in gear). * **Worn drive plate:** Change the drive plate. * **Propeller shaft hitting the Gearbox half coupling:** Move the shaft back to give at least 5mm clearance (Type 12/16 couplings only).
