4. TION Before removing your boat from the water unbolt and separate the transmission and propeller shaft flanges Check the alignment of the transmission output flange hd the propeller shaft flange with the boat in the water and fully loaded The fuel and water tanks should be full Proceed as follows 1 Disconnect the battery 2 Unbolt the coupling flanges see figure 3 3 With the flange pilot engaged check the clearance around the coupling flange using a 0 003 inch feeler gage 4 Rotate the transmission flange through one complete revolution stopping each 90 degrees to check the clearance with the feeler gage Repeat this procedure with the propeller shaft flange 5 The alignment is satisfactory when the flanges are within 0 003 inch 0 076 mm of parallel 6 If the alignment is unsatisfactory adjustment is required This adjustment is accomplished at the boat motor and transmission mounts ONLY This procedure should be accomplished by a skilled marine mechanic AX CAUTION Do not lift or pry against transmission output flange to move engine 7 When alignment is satisfactory install the coupling flange bolts and nuts Torque to 25 43 lb ft 34 58 Nm Figure 3 Coupling Flange Alignment 003 MAXIMUM FEELER GAUGE PROPELLER SHAFT FLANGE TRANSMISSION OUTPUT FLANGE Launch Maintenance cont d Shift Linkage Check AXCAUTION Incorrectly adjusted shift linkage may result in transmissi
