Chapter 2 N40475 Engine mounting brackets The standard brackets, provide mounting points which are 76mm (3”) below, and parallel with, the crankshaft centre line. The brackets may be used to mount the engine directly on the engine bearers, but for all applications it is recommended that flexible engine mounts are used. Figure 4 shows the holes (1) for the holding down bolts are slotted, 36 x 17 (1.7/16 x 21/32”) to allow for some movement during the final stages of alignment. Where fine alignment is not necessary, for example when a flexibly jointed drive shaft is used, the bolts on all four corners of the engine should be positioned at the end of the slot - all either fully in or fully out.
This will provide additional security in the fixing arrangements. Note: Please refer to the GA (General Arrangement) drawings for specific engine mount positions. For any non standard options, please contact the Wimborne Marine Power Centre for advice. Figure 4 Page 4
