7.5 Engine does not attain full revolutions
If the engine starts properly and runs smoothly, but does not reach the same revolutions as
previously, this does not necessarily indicate a defect in the engine, but may mean that there is
fouling on the bottom of the boat, or that it is over loaded. It is also possible that the propeller maybe
defective. If all these causes can be eliminated, there may have been a loss of compression in one
or more of the cylinders. Compression losing should be checked by professional.
7.6 Aligning engine and gearbox
Once a season or after launching, the alignment of the engine with the propeller shaft should be
check and if necessary adjusted. To do this:
Unfasten the screw union for the propeller shaft flange. Using a 0.10mm thickness gauge, check the
that there is not enough room to insert it between the reverse gear and propeller shaft flange any
point when the propeller shaft is pushed forwards. Turn the shaft through 90, 180 and 270 when
carrying out this test. If the gap is more than 0.10 mm the alignment should be adjusted. If a
non-adjustable rubber suspension is fitted, the thickness of the padding should be adjusted.
