Owner`s manual

3100 OFFSHORE

A standard in-line sea strainer is located above the intake thru-hull strainers. These should be visually inspected

periodically, by looking through the glass case, for accumulation of marine growth, weeds and other foreign

objects. If clogged or dirty, the strainer should be cleaned.

A CLOGGED SEA STRAINER AND/OR WATER INTAKE SCOOP CAN RESTRICT THE SUP-

PLY OF COOLING WATER TO THE ENGINE AND EXHAUST COMPONENTS, WHICH

COULD RESULT IN SEVERE ENGINE AND EXHAUST SYSTEM DAMAGE.

Cleaning the sea water intake scoops

Over time, barnacles or marine growth may accumulate under the intake

scoop. To clean the thru-hull fitting under the scoop, disengage the split

ring from the pin and remove the pin. The door will be free to swing

open. After cleaning, be sure that the split ring completely engages the

pin.

Cleaning the sea strainers

• Turn off the engines.

• Close the engine water intake valve.

• Open the top of the strainer and remove the screen.

• Thoroughly flush the screen and the inside of the strainer to remove

foreign matter.

• Lubricate the seal.

• Reassemble the strainer making sure that all fasteners are tight.

• Open the intake valve.

• Start the engine and inspect the strainer for leaks.

SHOULD AN ENGINE INTAKE, EXHAUST OR COOLING HOSE RUPTURE, TURN OFF THE

ENGINE AND CLOSE THE ENGINE WATER INTAKE VALVE IMMEDIATELY. PROCEED,

UNDER TOW IF NECESSARY, TO A SERVICE FACILITY FOR APPROPRIATE REPAIRS.

MAINTAIN A CLOSE VISUAL WATCH ON THE PROBLEM HOSE AND THE BILGE WA-

TER LEVEL.

Installation of “Fresh Water Cooling” provides adequate engine cooling without exposing the internal engine

cooling system to the harmful effects of surface water. This system is standard with diesel and gasoline engines

on the 3100 Offshore. The engine owner’s manual provides additional information regarding the service and

maintenance of this equipment.

1.5 Propellers

When the boats are shipped, the propellers are not factory installed. Initial installation of the propellers will

be performed by the dealer during pre-delivery service. Should it be necessary to change propellers, always

use an appropriate removal tool or “Prop Puller.” Do not attempt removal using a hammer. Damage to the

propeller, propeller shaft or transmission can result.

The following steps will enable you to install a propeller properly.
