'"e are sorry that as the engine is of obsolete pattern, we
have no printed spare parts list.
a. A new propeller tfill certainly "be necessary and a reducing
gear is certainly advisable. We have no reducing gear which
could be used with the existing reverse gear and therefore
recommend the use of our reverse gear type P/85 as described
in the enclosed leaflet MMD.1502,"with reducing gear.
This may be of either S - 1 or 5 - 1 ratio , the'latter
being recommended in the present case, driving a rropeller
of approximately 50" diameter but if this cannot be swung,
a S - 1 gear could be supp3ied with a slightly smaller
propeller.
The price is the same for either ratio and
the reverse and reducing gear with tailshaft^f 6 r an",
in length respectively and propeller and necessary 7ed^bars
connect with the engine, would be £835. (Two hundred &
thirty five pounds).
The following are the prices for additional tall and
intermediate shafting, etc. extra to the above standard
leng ths: -
Tailshaft, per foot.
Stern tube, per foot.
Intermediate shaft, per foot.
Half-couplings, each.
