Last updated on November 4th, 2022 at 11:30 pm

Technology has made our lives easier in mechanical advancements. Like in all the other fields of our everyday work, it has also made our lives easier in marine work. I am not talking about high-tech yachts or state of the art scuba diving equipment or submarines.

No, I am talking outboard mechanical motors for your simple wooden boats. This article is about the best outboard motor for saltwater available. The first-ever new outboard motors that made all the marine work easier was invented in 1909 by a Norwegian-American inventor called Ole Evinrude. Ole did a pretty good work here, something that can never be undone, even by the longest shot.

A Buying Guide To The Best Outboard Motor For Saltwater

If you are planning to buy an outboard motor for saltwater, you must know that buying a motor is more challenging than you think. It is not like any spare part of a car but you need to search for many places it the best. So, let us see what are these requirements to buy the best outdoor motor for saltwater.

Size Of Motor

  • Size is the primary concern while buying an outboard motor.
  • If the outboard motor’s size is bigger than required, at that point it can prompt the consumption or burning of plugs, which can bring about tremendous damage.
  • Also, if you purchase a motor smaller than the necessary size, it might exhaust itself and result in eroding very fast.
  • Moreover, it can likewise cause potential safety issues and an issue with the body of the boat.

Motor’s Type

  • While getting a motor type, you are offered two sorts of outboard motors, including a two-stroke and a four-stroke motor.
  • The in-centered distinction between two-stroke and four-stroke motors is that a two-stroke motor works with a combination of oil and gas, while a four-stroke engine works with gas.
  • A two-stroke engine is reasonable and light in weight. If you are searching for a major and weighty motor, at that point you need a four-stroke engine.

Horsepower

  • The ideal horsepower for your cruising boat relies upon the speed, cost of fuel kind, and the number of travelers.
  • Whenever you are finished checking these, you have to consider the size of the boat straight away.
  • Contingent upon the size of your cruising boat, the horsepower is coordinated.

Boat’s Size

  • In the event that you have a smaller length boat and use it for smaller water bodies, the horsepower of 10 would be enough.
  • If your boat is of fiberglass or aluminum, of 10 to 15 feet, it requires horsepower going between 15 to 20.
  • For a boat length of 15 to 25 feet, a horsepower of 75 to 90 is required. In the event that you need to cruise it quicker and travel farther, at that point a horsepower of 300 is required.

How to Select the Right Size of a Portable Outboard Motor?

As every boat hull is different, you need to cross check the size with the length of the boat, both in feet and length. Make sure the measuring with 

Motor Hp 

Boat Length (meters)

Boat Length (feet)

2 hp -10 hp

Up tp 3.5 m

8 inches – 12 inches

5 hp – 15 hp

Up to 4.2 m

8 inches – 14 inches 

9 hp – 20 hp

Up to 4.5 m

11 inches – 16 inches

20 hp – 40 hp

Up to 5.0 m

13 inches – 18 inches

40 hp- 75 hp

Up to 5.5 m

14 inches – 20 inches

90 hp – 140 hp

Up to 6 m and above

16 inches – 25 inches

The motor with 2 hp – 3.6 hp 

They are common for portable boats that have a weight of fewer than 18 kgs like inflatable boats, small sailboats, etc. and small light watercraft. In the following range, it would be typically restricted for one gear only and spins 360 degrees. With these motors, the hull moves 8 to 16 kmh and is light in weight and compacts in engines. 

Motor with 5 to 6 hp (18 to 25 kgs)

This kind of motor could be used in a variety of applications like small inflatable boats to 3.5 m in length with the larger 2.5 to 3.5m. Hull usually weight ranges between 22 to 113 kg with a small shaft that has 15 shafts however, these are all capable of 20. So, it could be the best 2.5 hp outboard motor and ideal for the sailing boat that is less than a 6m length. 

Such engines in the following hp range are usually 1-cylinder while there could be 2 cylinders. 

Motor with 8 to 9.8 hp (25 to 45 kgs)

This indeed looks small but is mighty outboard which is popular for the inflatable boats with 3m to 4.5m and aluminum boats 3m to 4.5m along with large durable canoes, large folding boards, and light fiberglass boats with 4.5m. 

The hull usually weighs 34kg to 136kg and requires 15 inches short shaft length outboard. This engine propels the hull 15 to 28 kmh approximately along with a person with a moderate load. Further, such motors are ideal for gasoline trolling motors and auxiliary kicker motors.

Is it safe to use an outboard motor in saltwater?

Most of the outboard motors are designed specifically for saltwater and freshwater. However, saltwater can make the motors corrosive, so, they are designed for making it stainless steel.  

As it is not something to buy frequently, that is why you have to take more care of saltwater outboard motors. However, we recommend Yamaha 200 outboard price which is affordable. Still, you have to take care of it like making it a routine to give the motor a wash after every water expedition.

The Outboard Engine Technologies

The outboard engine technology has experienced a renaissance. For decades, simple two-stroke carbureted outboards were the standard in the marine industry. The motor emission limits were strengthened, forcing manufacturers to make a choice.

What is the perfect outboard?

While choosing the best outboard for your boat, you usually get 2 different options which are either the Two-stroke or Four-Stroke.

Only a few outboards are there that use 2-stroke technology qualifying all the standards of laws and air quality. Usually, such works with the injection system for making the motor run smoothly without making noise. 

The four-stroke outboard is equipped with the latest and advanced features like visual and audible warnings in case of low oil pressure and overheating. It ignites with the electric start with 12v charging but it is offered as an optional model in such range.

Conclusion

Saltwater rapidly corrodes the metal bits (even aluminum hull) of the boat hull and this is something which is not bought often. Flushing the engine and cleaning the boat with freshwater is the key for every expedition. In this article, we have reviewed the best outboard motor for saltwater so find the right one..
