IV. After launching
1) Check for water or air intake around the gland part of the stern tube and the kingston cock
fitting.
2) Make sure that the engine installation bolts and shaft joints are firmly secured.
3) Release compression with the decompression lever and slowly run the engine with the
engine starting handle. Relative compression can be determined by comparing the weight (re-
sistance when turning) of the clutch handle when placed in the neutral, ahead, and astern
positions. When there is little weight difference among the three positions, decompression is
complete. If the clutch is heavier when engaged than when disengaged, this indicates that the
shaft is not in the correct position. If the engine is operated under this condition, a broken
propeller shaft may result. Check the alignment of the propeller shaft and the engine.
