Shaft Connection and Propeller Selection Some type of flexible coupling must be used to connect the gearbox output flange tothe propeller shaft flange. Please note, underperforming engines will not be covered under warranty if the causeof the poor performance is found to be the use of an inappropriate propeller.9. Engine Anti-Vibration Mounts Ensure that the engine feet do not end up at the top of the thread on the enginemounts, this puts undue pressure on them and can result in excessive enginemovement and premature mount failure. If this is a problem put steel packing platesunder the mounts. Packing plates 25mm thick are available: Order RDG3906 Enginemount spacer. Alternatively they can be manufactured locally. Ensure that the engine has been installed for at least 24 hours before shaft alignmentis checked, to allow the mounts time to settle under the engine weight. Ensure that the anti-vibration mount centre screw is sufficiently raised so as not totouch the engine bed. If this occurs, excessive engine vibration will be experiencedthrough the hull. For best results, fit the front AV mounts into the front holes in the engine rails. If theengine room space is a problem the mounts can be fitted slightly further back in theInletOutlet
