Where to Buy a 115 HP Outboard for Sale

A 115 hp outboard for sale is one of the most common repower classes on the water, especially for mid-size center consoles, bay boats, and pontoons that don’t need the extra weight and cost of a 150 HP engine. This guide compares three current 115 HP options side by side and what each one’s own spec sheet confirms.

This guide covers where to buy a 115 HP outboard online, what a 115 hp outboard price actually looks like, and how the Yamaha, Mercury, and Suzuki options stocked here compare on paper.

Why 115 HP Is a Popular Repower Class

115 hp four stroke engines sit a step below the 150 HP class, and they’re a common choice for boats that don’t need the extra power, or where keeping weight down matters for the hull’s rated capacity.

You can browse the full outboard motors category and filter to this horsepower class directly. For the full range of sizes and brands stocked here, our where to buy an outboard motor hub guide covers that ground first, and our 150 HP outboard comparison covers the class just above this one if you’re weighing both.

115 HP Outboard for Sale: Three Options Compared

Three current listings illustrate what’s available at this horsepower.

Yamaha F115XB

The listing here states 115 HP at 5,500 RPM, 1,832 cc of displacement, a 25-inch shaft, and 386 lbs. An independent engine review confirms 115 HP and 1.8 liters of displacement, and lists a 176 kg (about 388 lbs) dry weight, both matching the listing here closely.

Mercury 115ELPT FourStroke

The listing here states 115 HP, 2.1 liters of displacement, a 20-inch shaft, and 363 lbs dry weight. Mercury’s own Australian spec page for this class confirms 115 HP and 2.1 liters of displacement exactly, and lists 359 lbs for its lightest configuration or 363 lbs for the Command Thrust version, matching the listing here exactly at the heavier figure. (Mercury also sells a higher-output mercury 115 pro xs variant; that’s a different engine from the FourStroke featured here.)

Suzuki DF115B X

The listing here states 115 HP, 2,044 cc of displacement, and 412 lbs. Suzuki’s own US spec page for this model confirms 115 HP and a 2.0-liter displacement, matching the listing here, and lists 423 lbs for its 25-inch-shaft “X” configuration, 11 lbs over the 412 lbs shown on the listing here.

All three agree closely on their respective headline numbers, with the Suzuki showing a modest weight gap worth a quick confirmation if your transom rating is tight.

Confirm the model year and exact suffix shown on each listing against the current spec sheet before you order, since outboard model years don’t always match the calendar year.

Current pricing, exact shaft-length options and stock status are shown on each product page rather than reproduced here, since both change over time.

115 vs 150 Hp Outboard: Which Do You Actually Need?

A 115 vs 150 hp outboard decision usually comes down to boat weight, hull rating, and how you use the boat, not just which number sounds more powerful.

The best 115 hp outboard for a bay boat is often the lighter, more fuel-efficient option when the boat’s rated capacity doesn’t call for more power, while a heavier center console or a boat regularly loaded with gear and passengers may be better matched to the 150 HP class instead. Our 150 HP outboard comparison covers that tier directly if you’re deciding between the two.

Check Fit Before You Order

Shaft length is the single most common outboard buying mistake, and as the comparison above shows, even engines rated at the same horsepower don’t all ship with identical weight or displacement.

Run the specific model through the site’s own Compatibility Check tool before you order, and confirm shaft length against your transom measurement directly rather than assuming it matches your old engine.

What a 115 Hp Outboard Price Actually Looks Like

Our how much is a new outboard motor guide estimates new gasoline outboards in the 75 to 150 HP range at roughly $7,000 to $18,000, engine only, before installation, rigging, and taxes. The current listings in this comparison fall within that band, though the three brands here aren’t priced identically.

Brand, control type, and features like electric start and power trim all affect the final number more than horsepower alone does, so compare equivalent configurations rather than headline prices.

Shipping and Warranty, Briefly

Outboards ship as freight, with published US and Canada delivery windows of 7 to 14 business days, quoted at checkout based on weight and destination. New outboards carry each manufacturer’s own warranty, not a seller warranty; confirm that US warranty registration applies to your specific unit before you order, since registration and coverage terms can vary by region.

Our where to buy an outboard motor guide and the shipping information page cover delivery and inspection steps in more detail.

Common Mistakes Buyers Make

• Defaulting to the same horsepower as the old engine without checking whether the boat’s actual use calls for more or less.
• Assuming every 115 HP engine shares the same weight or displacement.
• Guessing shaft length instead of measuring the transom directly.
• Confusing a performance variant (like Mercury’s Pro XS) with the standard FourStroke at the same nominal horsepower.
• Not confirming US warranty registration applies before assuming full coverage.

When to Get Help Before You Buy

If you’re not sure whether 115 HP or 150 HP is the right size for your boat, or want help comparing these three 115 HP options directly, it’s worth asking first.

115 HP Outboard: FAQs

Where can I buy a 115 hp outboard for sale?

Universal Engine Parts currently lists 115 HP options from Yamaha, Mercury, and Suzuki, so you can compare displacement, shaft length, and weight before you check fit and order.

What’s the difference between this and a mercury 115 pro xs?

The Mercury 115 featured in this comparison is the standard FourStroke, built for efficient all-around repower use. Mercury’s Pro XS line is a separate, performance-tuned variant aimed at bass and performance boats, not covered in this specific comparison.

What does a 115 hp outboard price typically include?

The engine price alone typically runs within the $7,000 to $18,000 range for this general horsepower tier, before installation, rigging, controls, propeller, and taxes, which can add substantially to the total.

Is 115 HP enough, or should I consider 150 HP instead?

A 115 vs 150 hp outboard decision depends on your boat’s rated capacity and how it’s loaded in practice. Lighter boats and lighter use cases often do fine at 115 HP, while heavier boats or boats regularly loaded with gear may be better matched to 150 HP.

What’s the best 115 hp outboard for a bay boat?

It depends on the specific bay boat’s rated capacity and how you use it, but a lighter, fuel-efficient 115 HP engine is often a good match for bay boats that don’t need the extra weight or cost of a 150 HP engine. Run your exact boat through a Compatibility Check for a definitive answer.

Can you help me pick the right 115 HP option for my boat?

Yes. Send us your boat’s details and intended use through a Compatibility Check or Contact Us, and we’ll help you compare the real total cost of each option, not just the horsepower number.
