face water. This system is optional with gasoline
engines and standard with diesel engines on the
350 Sport Yacht. The engine owner’s manual pro-
vides additional information regarding service and
maintenance of this equipment.

A RUPTURED COOLING OR EXHAUST HOSE CAN
CAUSE SEVERE ENGINE DAMAGE OR ALLOW A
LARGE AMOUNT OF WATER TO FLOW INTO THE
BILGE. SHOULD AN ENGINE INTAKE, EXHAUST
OR COOLING HOSE RUPTURE, TURN THE
ENGINE OFF 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 WATER LEVEL.

Neutra-Salt Engine Flushing System
(Optional with Gas Engines)

Your boat could be equipped with the optional
Neutra-Salt Engine Flushing System designed to
provide you with an effective and simple solution
to flushing the seawater cooling system and com-
bat internal corrosion of your engine. The system
is designed with a solution reservoir for each en-
gine that is connected to the raw water intake
hose. A momentary rocker switch in the helm
activates a solenoid valve near each reservoir.
When activated, the system injects a concen-
trated solution into the seawater as it enters the
engine. The solution effectively neutralizes the
salinity of the seawater and applies a protective
coating to the metal surfaces.

1. To operate, simply engage the “Flush” switch

by pushing and holding the dash-mounted
switch for 45 seconds while running the en-
gine at idle speed, making sure the engine has
an adequate supply of raw water.

2. Once the Flush switch is engaged, the

Neutra-Salt concentrate solution will be in-
j e c t e d i n t o t h e c o o l i n g s y s t e m ,
leaving a corrosion-inhibiting coating on all
metal surfaces, thereby neutralizing the sa-
linity of incoming seawater.

3. Before disengaging the Flush switch, you must

turn off the engine. For best results, use the
Neutra-Salt Engine Flushing System after ev-
ery trip outing. You will typically get 10 to 15
flushes before a refill is needed.

Refer to the Neutra-Salt owner’s manual for spe-
cific information on the system installed in your
boat. It is important that you completely under-

stand the system in theory and operation to
achieve the best results. Contact your Monterey
dealer to acquire solution for refills.

1.5 Propellers

The outdrive uses dual, counter rotating propel-
lers that convert the engine’s power into thrust.
They come in a variety of styles, diameters and
pitches. The propellers that will best suit the
needs of your 350 Sport Yacht will depend some-
what on your application and expected average
load. Propeller sizes are identified by a number
stamped on the prop. The 1st number in the
sequence (example 14 x 21) is the diameter of
the propeller and the 2nd number is the pitch.
Pitch is the theoretical distance traveled by the
propeller in each revolution. Always repair or re-
