P30 R silent rubber blocks should be compressed to 13 mm P60 K to 16 mm and P80 S up to P1000 L to 15 mm as indicated in drawing No 5 Please note should the mounting plate not be at right angles to the prop shaft adjustment is possible by shimming between the rubber blocks and the mounting plate Model PD G P1000 G has polyurethane thrust blocks where the above Al described compression does not apply but shimming may be neccessary 5 Drive shaft lengths and angles We recommend the flexible drive shaft installation lengths and angles are thoroughly checked This procedure is important due to the movement that may be inherent within the installation Where engines are mounted on flexible mounts there is always a tendency for the installation to move fore and aft in addition to port and starboard Allowing for plus or minus 2 mm the net length of the flexible drive shafts of the models from P30 K to P140 T and for plus or minus 3 mm for P200 and P501 can be taken from the drawings attached to this manual these dimensions L as indicated in drawing No 6 For model P1000 also see these drawings allowing for plus or minus 12 mm see last pages of this manual A simple way to determine the actual length is to measure both the longer side and the shorter side and to average them out This must be the length of the flexible shaft you have chosen If the location points are out in more than one plane measure both pla
