Engine Terminology Guide

Horsepower (HP)

A unit of measurement for engine power. 1 HP = approximately 746 watts. Higher horsepower means more thrust and speed, but also more weight and fuel consumption.

Displacement

The total volume of all cylinders in an engine, measured in cubic centimeters (cc) or liters (L). Larger displacement generally means more power and torque.

Cylinders

The number of combustion chambers in the engine. Common configurations:
  • Single-cylinder: 1 cylinder — lightweight, simple, lower power
  • Inline-2: 2 cylinders — compact, moderate power
  • Inline-3: 3 cylinders — smooth, good power-to-weight ratio
  • Inline-4: 4 cylinders — very smooth, excellent power
  • V6: 6 cylinders in a V configuration — high power, compact
  • V8/V10/V12: 8, 10, or 12 cylinders — maximum power for large vessels

EFI (Electronic Fuel Injection)

A fuel delivery system that uses electronic sensors and injectors for precise fuel metering. Benefits include better fuel economy, easier starting, smoother operation, and lower emissions compared to carburetors.

Carburetor

A mechanical fuel delivery system that mixes air and fuel. Simpler and lighter than EFI, but less efficient and requires more maintenance.

2-Stroke vs. 4-Stroke

Table

Feature 2-Stroke 4-Stroke
Power strokes per cycle 1 per revolution 1 per 2 revolutions
Weight Lighter Heavier
Fuel efficiency Lower Higher
Emissions Higher Lower
Noise Louder Quieter
Maintenance Simpler More complex
Oil mixing Required (pre-mix) Not required (separate oil system)
Note: Most modern outboards are 4-stroke due to environmental regulations and fuel efficiency advantages.

Shaft Length Standards

Table

Designation Length Typical Use
Short (S) 15″ (381 mm) Small boats, inflatables, jon boats, tenders
Long (L) 20″ (508 mm) Standard fishing boats, runabouts, pontoons
Extra Long (X) 25″ (635 mm) Deep-V hulls, offshore boats, sailboat auxiliaries
Ultra Long (U) 30″ (762 mm) Large offshore boats, commercial vessels
Measurement: Shaft length is measured from the anti-ventilation plate (just above the propeller) to the top of the mounting bracket where it meets the transom.

Propeller Specifications

Propeller Dimensions

Propellers are described by two numbers: Diameter x Pitch
  • Diameter: The overall width of the propeller circle (in inches)
  • Pitch: The theoretical distance the propeller would move forward in one revolution (in inches)

Propeller Materials

Table

Material Characteristics Best For
Aluminum Affordable, lightweight, replaceable General recreational use, smaller motors
Stainless Steel Durable, efficient, better performance High-performance boats, larger motors
Composite/Plastic Very lightweight, corrosion-proof Small motors, trolling, backup props

Propeller Blade Count

Table

Blades Characteristics Best For
3-Blade Standard, good all-around performance Most applications
4-Blade Better acceleration, lift, and handling Watersports, heavy boats, rough water
5-Blade Maximum grip and smoothness High-performance, offshore

Propeller Hub Systems

  • Through-Hub Exhaust: Standard on most outboards; exhaust exits through the propeller hub
  • Over-Hub Exhaust: Used on some high-performance applications
  • Dual-Prop (Counter-Rotating): Two propellers on one shaft rotating in opposite directions; maximum thrust and efficiency

Fuel System Specifications

Fuel Types

Table

Type Description Common Brands
Unleaded Petrol (95/98 Octane) Standard fuel for most 4-stroke outboards All major brands
Pre-Mix (2-Stroke Oil + Petrol) Required for 2-stroke engines Older models, some racing engines
Diesel Used in inboard diesel engines Yanmar, Volvo Penta

Fuel Tank Options

  • Internal Tank: Built into the outboard (small motors, typically under 10 HP)
  • External Portable Tank: 12L, 25L, or 50L portable tanks with fuel line
  • Built-in Boat Tank: Permanent tank integrated into the boat’s hull

Fuel Consumption (Approximate)

Table

HP Range Fuel Consumption at WOT
2.5–10 HP 0.5–2.5 L/hour

100–200 HP 30–70 L/hour
200–350 HP 70–120 L/hour
350+ HP 120+ L/hour
Note: Actual consumption varies based on boat weight, hull design, load, sea conditions, and throttle setting.
