Choosing the right engine for you can greatly impact how you use your boat and how you maintain it.

It is not as simple as just choosing a model and horsepower. There are four main types of engines: inboard, outboard, sterndrive and jet drive.

Inboard vs Outboard Engines

An inboard engine is like a car, the motor is mounted inside the boat usually on the lower aft of the boat. This follows down to the outdrive unit which is situated outside the boat at the aft.

An outboard engine houses the motor and the lower outdrive on the exterior aft of the boat in its own unit.

Inboard Engines

Pros

• Smoother
• Similar experience as driving a car
• Quieter
• More fuel efficient
• Longer lifespan
• Aesthetics

Cons

• Takes up space in the boat
• More expensive to maintain and winterise
• More components and therefore heavier

Outboard Engines

Pros

• More compact and therefore takes up less space
• Light weight and easier to work on
• Easier for repairs and replacements without professionals
• Lower maintenance costs
• Not susceptible to freeze damage – prop and drive unit can be lifted out of the water
• Trimming up the prop and drive unit makes easier access to shallower waters

Cons

• Louder than inboard engines
• Currently older in regards to the technology
• Less fuel efficient
• Some say it ruins the aesthetic
