What type of hand tools are essential for basic maintenance tasks on a marine engine?

• Power tools with extended reach attachments

• A comprehensive set of wrenches, sockets, and screwdrivers

• Specialised tools designed for specific engine models only

• Multipurpose tools that can handle all potential situations

Why are pliers a valuable tool in a marine engine maintenance kit?

• A) They are primarily used for cutting wires and cables.

• B) They offer gripping and manipulating capabilities for various tasks.

• C) They are best suited for heavy-duty jobs requiring high torque.

• D) They can replace the need for wrenches and screwdrivers in most cases.

What role do torque wrenches play in marine engine maintenance?

• A) They measure engine speed and RPM during operation.

• B) They ensure proper tightening of bolts and fasteners to specified torque values.

• C) They replace the need for standard wrenches for faster tightening.

• D) They are only necessary for major engine overhauls.

What safety equipment should be readily available when working on a marine engine?

• Heavy-duty work gloves for added gripping power

• Safety glasses, gloves, and appropriate footwear

• A respirator for protection against engine fumes

• All of the above

When lifting engine components, what type of equipment should be prioritised for safety?

• Improvised solutions using ropes and chains

• Lifting equipment with a rated capacity exceeding the component's weight

• Relying solely on manpower for all lifting tasks

• Using the engine itself as a lifting point for attached components

Why is maintaining a stock of essential spare parts crucial for a marine engine maintenance program?

• To have replacement parts readily available for unexpected repairs.

• To avoid relying on potentially incompatible parts from other vessels.

• To reduce repair costs by bargaining with suppliers for bulk purchases.

• Spare parts are readily available at most marinas, eliminating the need for a stock.

What types of cleaning materials are appropriate for marine engine maintenance?

• Harsh abrasive cleaners that remove all grime and residue

• Degreasers, solvents, and cloths specifically designed for marine engines

• General household cleaning products readily available at home

• Water alone is sufficient for cleaning most engine components

What considerations are important when selecting electrical connections for marine engine applications?

• Using standard household electrical connectors for convenience.

• Choosing marine-grade connectors designed for water resistance and corrosion protection.

• Prioritising low-cost options regardless of their durability in a marine environment.

• Selecting connectors based on size and appearance only.

Why are engine filters replaced regularly as part of a maintenance program?

• To improve the visual appearance of the engine compartment.

• To remove contaminants and ensure optimal engine performance.

• Filters only need replacing when they become visibly clogged.

• Replacing filters is unnecessary for most recreational marine engines.

What is the primary function of gaskets used in a marine engine?

• To improve the engine's overall aesthetic design.

• To create watertight and airtight seals between engine components.

• To act as decorative elements to cover up engine parts.

• Gaskets are not typically used in modern marine engine designs.
