PROPULSION SYSTEM
1.1 General
The Pursuit 3100 Offshore is designed to be powered with twin gasoline or diesel inboard engines. Each
manufacturer of the various marine power components provides an owner’s information manual with its
product. It is important that you read the manual(s) very carefully and become familiar with the proper care
and operation of the engines and drive systems. A warranty registration card has been furnished with each
new engine. 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 Drive Systems
On inboard propulsion systems, all shifting and gearing components are installed inside the hull. Only the
propeller shafts and associated equipment are under water. The engines are mounted below the bridge deck
sole. A transmission, also called a gearbox, which performs desired shifting functions, is directly coupled to
each engine. The propeller shaft extends through the hull and connects the transmission output coupling with
the propeller. Some inboard transmissions have built-in reduction gearing. This gearing reduces the speed
of the propeller in relation to engine speed.
ALWAYS RETURN THE ENGINE THROTTLE LEVERS TO THE EXTREME LOW SPEED
POSITION BEFORE SHIFTING. NEVER SHIFT THE TRANSMISSION AT ANY THROTTLE
SETTING ABOVE IDLE RPM.
All transmissions require oil or fluid of some type for lubrication. This level should be checked at the same
interval as the engine oil level.
Your boat is equipped with transmissions supplied by the engine manufacturer. For details on the
transmissions, refer to the engine or transmission owner's manual.
