7.10 Removal of Propeller

For both solid and folding propellers, a propeller puller is required which can be purchased at

any marine dealer.

Procedure for Removal of a Martec Folding Propeller

(a) Remove all cotter pins from pivot bar for blades and shaft. Save cotter pins if possible.

(b) Pull pivot bar from the blades. Some propellers are tapped for a bolt on one end of the

pivot bar. Thread a bolt into this end of the pivot bar and pull same by means of bolt. On others

the bar can be tapped out with a drift punch and hammer.

propeller hub on folding propellers and exposed on solid props. For removal of the shaft nut on

the folding prop, a 1/2" square drive handle with extension is required and a socket for the

standard prop.

(d) When removing the propeller, leave the prop retaining nut in place 1 to 2 turns loose

from the tight position for protection of the threads. The puller shaft should never bear directly

on the end of the propeller shaft. Since it bears on the propeller retaining nut, a brass aluminum

or copper spacer should be used for protection of the nut.

The puller must be installed straight and centered carefully in order to utilize its maximum

effectiveness. The claws of the wheel puller should be placed behind the prop hub.

If a Gori folding propeller has been installed, the procedure is similar but allen screws are used

in lieu of cotter pins.

7.11 Exhaust System

The exhaust system on the CS 36 utilizes a "pot" type muffler. At engine running condition an

auxiliary water pump draws water through the intake port, circulates it through the heat

exchanger and thence into the muffler. The water mixes with the exhaust gases in the muffler

and is discharged overboard through the exhaust port at the aft port side of the hull.

NOTES RE: EXHAUST VENT: To prevent water being sucked back into the engine when shut

down, a vent is fitted into the exhaust manifold elbow and piped to a 90° elbow fitting in the

starboard topsides. Under certain load conditions, cooling water will flow through the vent and

be discharged overboard. On a regular basis check that this is happening; no water indicates

the pipe of fitting is blocked and needs clearing.

The raw or salt water in the hear exchanger lowers the temperature of the engine coolant

circulated through the engine block with the engine water pump.

This coolant consists of a 50% ethylene glycol and 50% fresh water solution and protects the

internal system down to -32°F (-35°C) This solution should be used at all times for engine
