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.
