*113. BILGES.--Although Kelvin engines are oil tight, it is impossible to avoid some
spillage when pipes are detached for the cleaning of filters. Instead of attempting to
catch this by means of drip trays, it is more practical to provide for the easy cleaning
of the bilges. All floor boards should be portable and the engine room bilge should be
isolated. Cleaning is a simple matter if done as follows

    Pump out the salt water, and substitute fresh; add 7 pounds of washing soda,
dissolved in hot water; swab the bilges with a mop. If enough fresh water is available
the rolling of the boat may be utilised to do the work of swabbing.

114. LINER EXTRACTING TOOL.

--(a) Oil the stud so that the nut is perfectly

free; (b) bring the piston to its lowest position; (c) assemble the tool as shewn, spacing
the (6 or more) teeth equally around; (d) tighten the nut; (e) rotate the flywheel from
side to side while maintaining a tightening pressure on the nut.

115. KELVIN STEERING AND CONTROL COLUMN.

    This should be installed according to the catalogue. The stopper chain should be
adjusted to allow the helm over 45 degrees each side. After installation test as
follows:-

    Put the helm over until the stopper chain is taut and apply your full strength to the
wheel. Repeat the test to the other side. When the speed control lever is moved from
side to side, the governor lever should come against its upper and lower stops.

    The weight of the vertical rod should be borne by the balance spring. This may be
checked by detaching it from the governor lever. The deck shaft should be perfectly
free in its bearings.

    The chain pulleys are fitted with "Oilite" bushes. No lubrication is required.

    The deck bearing of the helm stock has space for a little cotton to retain the oil.
This may be inserted through the oil plug.

    Test the water-tightness of the steering column at the deck by pouring water around
it.

MONTHLY ATTENTION.--Remove the steering column cover and oil the chain
and bearings. Remove the oil plug from the deck bearing of the helm stock and fill
with oil. Oil the chain where it works through a pulley or a lead.
