Installing a motor in an aluminum boat is just a piece of cake. To achieve maximum efficiency, you’ll have to give it 50 to 300 horsepower. There’s a range of the required power as you take into consideration the size and usage.

An aluminum boat that is 16 feet long needs to have a 60 horsepower motor. Once equipped, it can have a speed of 25 to 30 miles per hour. That is why when you have the right motor for your aluminum boat based on its size, it won’t cause any disadvantages.

However, the load will affect the rate. Hence, anticipate some changes as passengers and load will set variations on the speed.

Engine and Speed

The aluminum boats with an engine of 250 to 300 horsepower typically have a 55 to 60 mph wide-open throttle. These numbers may be more than enough with two passengers on board.

However, large and expensive engines are not compatible with aluminum boats with 16 to 24 feet. Engines with 115 to 150 horsepower suit these boat sizes. They can have 23 to 28 mph along with the allocated fuel economy.

These engines’ WOT ranges from over 30 to mid 40 mph. A 60 horsepower added to your 16-foot aluminum boat will propel the engine to gain the speed of 25 to 30 mph. There will be a different count as the load varies on every boat.

It’s not always necessary to upgrade to a larger engine. Ask yourself why you need such humongous horsepower, or is it only a whimsical assumption?

Fuel consumption is a part of the evaluation as the motor won’t work without it. Keep in mind that the amount of power is linked to the engine’s horsepower.

About the Price

Don’t be surprised if the motor that you need is on the pricier side. Substantial onboard engines cost a lot in the current market, and that’s a fact. However, it’s a worthy investment as you can depend on it in the long run.

If ever you sell your boat, the motor will be the hot item and quickly sold out. So there’s no room for regret in spending on it.

Wrapping it Up
