Why Suzuki Outboard Engines

Suzuki has not produced outboard motors in decades. More powerful, more efficient, and longer-lasting with their improved engineering expertise, Suzuki motors are the choice of anyone who fishes. Cruising loaded up or light, or just running, Suzuki outboards are the choice of reliability, long life, and power.

Some of the reasons Suzuki outboards would be the complete addition to your 20ft boat are:

Fuel Efficiency: Suzuki fuel-efficient engines allow you to travel wherever you want on a tank of fuel without cashing in the extra funds, which is great if you are going to be using your boat extensively.

Endurance: Suzuki invests quality materials and careful engineering into making their outboards, which have been able to withstand heavy use.

Silent Running: Suzuki cutting-edge technology allows their outboards to be quieter than most, for a more quiet boating experience.

Advanced Technology: Suzuki outboards feature advanced technology in the shape of Lean Burn Control to provide better fuel economy, and Suzuki Precision Control to provide smoother gear change.

Durability: Suzuki outboards are tough enough for use in saltwater and freshwater, so they are good enough for any application in a boat.

Issues to Be Addressed for a 20ft Boat

There are a few things to consider when selecting an outboard for a 20ft boat. They are:

  • Power and Weight: A 20ft boat will already come with an engine size that will be ideal for it, but if you install a too heavy or light outboard, it will be detrimental to the handling of the boat. Power is also something to consider in order to make sure that when you need maximum performance and handling.
  • Fuel Efficiency: Long-distance boating requires an international-standard fuel-efficient engine. Suzuki outboards meet the challenge and reduce refueling stops.
  • Reliability: By being able to battle through tempests or cruise around a lake during the day, reliability makes boat travel as simple as strolling in the park.
  • Ease of Handling: Check how simple it is to drive, gear shift, and maneuver the outboard motor. Suzuki outboards have been renowned across the world for ease of handling, i.e., Suzuki Precision Control system.

Expert Tips

Before you commit, write down how you really use the boat: how many people you carry, how far you go, and whether you need to plane quickly or cruise slowly. That picture makes it much easier to choose the right horsepower, shaft length, controls and propeller, and avoids paying for features you will not use.

Read the model code on any listing carefully. Letters in the code usually describe shaft length, starting method, steering, trim and rotation, and two engines that look identical in photos can be set up quite differently. If anything is unclear, ask before you order.

Key Points to Remember

  • Start with your boat’s capacity plate: never exceed the rated horsepower or weight.
  • Match the shaft length to your transom height.
  • Choose tiller or remote steering, and manual or electric start, to suit how you use the boat.
  • Read the model code carefully; it tells you shaft length, controls, rotation and colour.
  • Budget for the full package: controls, gauges, propeller, battery and rigging.
  • Confirm exactly what is included with the engine before you order.

Practical Checklist

Use this quick checklist to put the advice in this article into practice:

  • Check the capacity plate for maximum horsepower and weight
  • Measure transom height from the top of the transom to the bottom of the hull
  • Decide on steering, starting and trim requirements
  • Compare model codes and specifications
  • Ask what is included: propeller, controls, fuel tank, cables
  • Inspect the crate on delivery and note any damage before signing

Frequently Asked Questions

What shaft length do I need?

Measure from the top of the transom to the bottom of the hull on the centreline: about 15 inches suits a short shaft, 20 a long shaft, 25 an extra-long shaft and 30 an ultra-long shaft.

Should I buy new or used?

New engines give you a known history and full manufacturer support. A well-documented used engine can save money, but check hours, compression and service records carefully.

How much power do I really need?

Most owners choose an engine at 75 to 100 percent of the boat’s rated maximum, which usually gives the best balance of performance, economy and resale value.
