Outboard Buying Guide

Wondering where to start? There are three key things to consider:

The purpose of your vessel:

Choosing the right outboard motor starts with considering how you use your boat and what type of vessel you're powering. Different boating activities, from weekend cruising to commercial fishing, demand specific performance characteristics, fuel efficiency, and durability levels.

When we're talking about the Mercury Marine range:

  • FourStroke models are ideal for recreational boats, offering smooth, quiet operation and fuel efficiency.
  • ProKicker™ models are purpose-built as auxiliary or "kicker" motors for precise boat control during fishing and trawling.
  • SeaPro™ models are engineered for commercial-grade durability and extended operation under demanding conditions.

You can find more info on outboard ranges at Mercury Marine.

What length driveshaft do I need?

Choosing the correct driveshaft length is essential for performance. Measure the transom of your vessel from top to bottom in inches to determine the correct shaft length.

Understanding engine capacity

Engine capacity must match your boat's size and usage by law. You can find the maximum engine power rating information for a recreational vessel on its Australian Builders Plate (ABP), which will be permanently mounted in a visible location - typically on the transom or near the helm.
