ENGINE!
After the stuffing box is installed, support!
the shaft slightly upward to relieve its weight on!
the lower part of the stuffing box, lower the engine!
and insert the propeller shaft into the "Hurth" V-!
drive transmission. The adjustable engine supports!
are then centred in such a way as to allow upward!
and downward adjustments later on. Measurements are!
then taken from under the supports to the hull to!
determine the shape of the engine bed.!
ENGINE BED!
Remember that since the engine shaft is off centre, so will the engine, and therefore the
engine bed will have an uneven shape. We recommend that the engine bed be fabricated
of 2" thick solid mahogany or three 3/4" pieces of mahogany plywood glued together.
These engine beds are then glued to the hull under the engine supports using "More
Bond" putty. Then, the engine is removed and the engine bed is laminated in place using a
minimum of two 24 oz. roving, and one 1 oz. or l£ oz. mat in between them.!
Do not forget that the engine bed not only!
supports the weight of the motor, but actually the!
force of the propeller is transferred through the shaft!
and the engine and onto the engine bed and then into!
the hull, and it actually carries the whole pushing!
weight of the boat. The installation of the bed and the!
laminations must, therefore, be taken very seriously.!
