OS 315

Chapter 1:

PROPULSION SYSTEM

1.1 General

The Pursuit OS 315 is designed to be powered with twin 2-cycle or 4-cycle outboard motors.

Each manufacturer of the various outboard motors provides an owner’s information manual which includes

its limited warranty statement with its product. It is important that you read this information very carefully

and become familiar with the warranty and proper care and operation of the engine and drive system. A

warranty registration card has been furnished with each new engine and can be located in the engine owner’s

manual. All information requested on this card should be filled out completely by the dealer and purchaser

and then returned to the respective engine manufacturer as soon as possible.

DO NOT ATTEMPT TO SERVICE ANY ENGINE OR DRIVE COMPONENT WITHOUT BE-

ING TOTALLY FAMILIAR WITH THE SAFE AND PROPER SERVICE PROCEDURES. CER-

TAIN MOVING PARTS ARE EXPOSED AND CAN BE DANGEROUS TO SOMEONE UNFA-

MILIAR WITH THE OPERATION AND FUNCTION OF THE EQUIPMENT.

USE ONLY CLEAN, DRY FUEL OF THE TYPE AND GRADE RECOMMENDED BY THE EN-

GINE MANUFACTURER. THE USE OF INCORRECT OR CONTAMINATED FUEL CAN

CAUSE ENGINE MALFUNCTION AND SERIOUS DAMAGE.

1.2 Outboard Saltwater Application

Each outboard motor is a complete drive system with the gear case being just forward of the propeller and

connected to the power head with a vertical drive shaft. Other than the routine maintenance outlined in the

engine owner’s manual, there is little to be concerned with unless the boat is to be kept in saltwater for extended

periods of time. Then the main concerns are marine growth and galvanic corrosion.

Marine growth occurs when components are left in the water for extended periods and can cause poor

performance or permanent damage to the exposed components. The type of growth and how quickly it occurs

is relative to the water conditions in your boating area. Water temperature, pollution, current, etc. can have

an effect on marine growth.

Galvanic corrosion is the corrosion process occurring when different metals are submerged in an electrolyte.

Sea water is an electrolyte and submerged engine components must be properly protected. Outboard motors

are equipped with sacrificial anodes to prevent galvanic corrosion problems. The anodes must be monitored

and replaced as necessary. For locations and maintenance, please refer to the engine owner’s manual.

When leaving the boat in the water, tilt the motors as high as possible. This will decrease the risk of marine

growth around the cooling inlets, propeller and exhaust ports and damage from galvanic corrosion.
