Your propeller matters more than you think. A poorly chosen prop can overwork your engine, take a toll on your RPM, and undermine what your boat’s actual power. So yes, it’s imperative that you choose the right prop - especially if you’re cutting through the waves with a high-speed deck boat.

Unbeknownst to most boat owners, there’s actually a specific science to choosing a prop for a deck boat. And if you’re not privy to the nitty gritty just yet, here’s everything you need to know about choosing the best prop for deck boat use.

The 3 Best Propellers for Deck Boats

Just for the record, every deck boat is designed differently and there are specific measurements and considerations you need to make in order to guarantee that the propeller you’re getting is actually the right one for your boat.

All of that aside, these props are some of the best on the market. So if you find that your boat might work well with one of these, it’s probably a good idea to cop them while they’re in stock.

How to Choose the Right Prop for a Deck Boat

Just a gentle reminder - every boat is different. And while we might be able to provide you a template of what works for deck boats, it’s important that you ask a professional or your dealership as too what prop they can recommend for your boat if you’re not too experienced yourself.

Generally, deck boat props need to have three things: 

  1. Low cup - The cup is basically the curvature of the prop blade. You want this to be as subtle as the design will allow.
  2. Low pitch - Pitch refers to the distance your prop travels with a single revolution. Unfortunately, the measure isn’t as simple as it seems and will depend on a number of external factors
  3. Low rake angle - Rake angle refers to how slanted your propeller blades are.

For a deck boat, all of these measures need to be low to maximize speed and fuel efficiency.


Today, deck boat propellers are available in three main materials. They all have their own distinct pros and cons, so understanding the differences should help you make a more informed choice for your specific boating needs.

  • Aluminum is common, affordable, and lightweight. They’re great for casual boaters.
  • Composite is much cheaper and work best for performance boaters. Keep in mind though that once they’re damaged, there’s no way to fix them.
  • Stainless steel provides the best speed and durability, however they can be pretty expensive and may require some maintenance.

Testing Your Prop

Once you’ve purchased a replacement prop for your deck boat, you should make sure to test it out. You can do this by installing a tachometer. The purpose of this tool is that it gives you an RPM reading while you’re out on the water.

Start your engine and drive your boat as you normally would. Take a look at the reading on the tachometer - is it higher or lower than what’s indicated as the average RPM for your deck boat under your user manual?

If the RPM is off by a negligible margin, then your prop choice should be just fine. But if your boat is churning out an RPM that’s too low compared to its ideal measure, your propeller pick might be off target.

Remember, choosing a propeller with the wrong size and specs can overwork your engine. According to experts, every inch of unnecessary, extra diameter size can reduce your RPM by up to 500. Every added inch of blade pitch can reduce your RPM by an added 200.

Ask a Professional

If you’re not sure about all the technicalities and you want to get it right on your first try, make sure you ask a professional. Better yet, you can call up your dealership or the manufacturer and they should be able to point you in the direction of an appropriate prop for your deck boat. In some cases, they might even be able to offer you one from their stock.
