Propeller

3 blade Gori feathering propeller. File:Mashnee gori prop.pdf and File:GORI Manual-15-16 5-Overdrive-Shaft-A4-3.pdf

Folding the Propeller

Put the gear shift in reverse when the engine is off. This locks the shaft and ensures the propeller folds and does not spin. Then return the lever back into neutral.

Normal Ahead

If you want to shift from "overdrive" to normal/forward position, the lever will have to be put into neutral when the boat does more than 1 knot ahead until the blades have folded again, then put it in the forward position again. If the propeller is spinning with the engine in neutral, you must go gently in reverse, while the boat is moving forward. After the propeller has been going in reverse for a few seconds, you can go back to neutral and the propeller will have folded and the shaft stopped. when you back to forward, the propeller will be in normal ahead. Before leaving the harbor, always check the position of the propeller by means of the boat's tachometer so that the propeller is in the wanted position.

Going Astern

in the reverse position the blades swing 180 degrees opposite the forward position which ensures the same blade leading edge and profile, resulting in high-efficiency. If the boat has not been used in some time, you should shift cautiously between forward and reversed a few times before sailing in order to clean the teeth of the blades and the gears from fouling.

Going Ahead in Overdrive

The “Overdrive” function is to be used when motoring at a cruising RPM in fair weather or when motorsailing. Overdrive is a second larger pitch achieved by going forward with the propeller blades in the reverse position. The second higher pitch acts like 5th gear in a car and likewise can increase speed and efficiency.

In order to position the propeller in forward "overdrive" it is necessary to move the boat astern so that the blades are kept in reverse position when the lever is put into forward. Do not try to make the propeller go from forward to "overdrive" position by quick shifts with the lever when the boat is sailing ahead in the water. When in reverse position, the blades have a 20% higher pitch than forward. when you go forward with the propeller in the reverse position, this higher pitch is kept, enabling overdrive. If you are in standard forward at the higher RPM and want to go into overdrive:

• 1. Reduce the engine RPM and put the shift lever into neutral
• 2. Go into reverse
• 3. Raise the engine RPM several hundred for a few seconds
• 4. Reduce the engine RPM and move the shift lever to forward smartly without hesitation You will now be in overdrive.

If you are in overdrive and want to go into standard forward:

• 1. Reduce the engine RPM and put the shift lever into neutral
• 2. Bump into reverse for a second which stops the shaft immediately
• 3. Wait several seconds (shaft should stop rotating), blades fold closed from forward motion and then shift back into forward
• 4. This will give you the standard forward position. By bumping into reverse and leaving the engine in neutral for several seconds you are allowing the shaft to stop rotating and the propeller blades to fold closed (action of water flow over the positively geared blades), then when you go back into forward the blades will open in the standard forward position.

Often just after leaving the marina slip you may find that the propeller is in Overdrive. This is due to when backing out of the slip and then shifting the into forward position - while the boat was still moving backwards - the blades will be in the overdrive position. Simply put the shift lever into neutral for a few seconds, make sure the shaft stops turning (bump into reverse for a second) and then back into forward and you will be in the standard forward. Many Gori customers use overdrive for the vast majority of their motoring, only using standard forward in conditions that require great thrust and high RPM such as to power through heavy seas or quickly maneuver.

Fuel System

20 Gallon diesel fuel tank.

When the tank is full, the fuel gauge reads "F". When the tank is 10 gallons down, the fuel gauge reads "E". The gauge seems to be non-linear and should not be relied upon for accurate measurement of the fuel tank.

NMEA 2000 network

There is a standard NMEA 2000 network with most connections behind the false panel in the aft-most port cupboard (above the ice box). The backbone has been extended using .5 meter backbone cable and a drop tee. There is an additional set of connectors in the forward compartment just to port of the mast. There is one free port at the mast.

• MMSI Number: 338236803 (assigned via SeaTow)

Magnetic Compasses

There is a magnetic compass which is placed in the starboard cockpit locker. When it is deployed it is mounted on a small brass rail at the foot of the companionway.

Note, this compass cannot be trusted. Compasses do not take hard knocks well, and there is no guarantee that its placement is not in a magnetically pathological location. This compass can be used for relative heading hold, e.g. maintaining a number. However, the absolute values are not to be trusted at all. [KDS]

Galley

Stove

The stove is an Orico-style alcohol stove. Alcohol does not burn as hot as propane so it takes longer to cook.

To operate the stove, remove the wooden plate and place it above, where the metal underside will serve as a heat deflector.

The top of the stove needs to be open to reveal the metal canister underneath. There is a black rubber disk which seals the canister and keeps the alcohol from evaporating. Remove this.

Ensure that the stove dial is turned to the on position, and then the stove can be lit with a lighter or match.

The stove is extinguished by turning the dial fully off, and then replacing the rubber disk and the wooden cover.

Ice Box

• There is a sump under the ice box to collect the meltwater. This sump can be emptied via the salt water foot pump for the sink if the cross-flow valve underneath the sink is switched. The valve has a pointer on it and the pointer must point up (12:00) for sump drain and to the right (3:00) for the salt water intake.
