Installation for special conditions
CONDITION 1
When space between propeller and strut is too narrow to mount cutter:
OPTION 1:
Removal of a ring from strut boss the width necessary to allow enough space for mounting cutter, including any end play. Procedure is as follows:
a) Scribe a ring around strut allowing space for cutter and end play (Photos 15, 16 and 17).
b) Cut strut through bearings stopping at rubber; using a knife, cut through rubber and removing. Make a side cut before a complete cut when propeller is not removed (Photo 18).
c) Remove ring and follow installation instructions.
OPTION 2:
Install SPURS® Spacer between transmission and shaft flange. A 1" spacer will lengthen shaft allowing an additional 1" for cutter to be installed. (Photo 19).
SPURS® Spacers are available through Spurs Marine:
Contact us for sizing. We will need the Make and Model of your transmission.
SPURS® Spacers are solid steel, machined parallel within .001 and are electroless nickel plated.
CONDITION 2
Too much space between propeller and strut or stern tube:
(Photo 20) Contact us for special instructions. When a vessel with an unusual arrangement is encountered , send drawings for factory installation assistance. A zinc collar between propeller and cutter will act as a filler.
