Boatman 14x19 Aluminum Propeller for Suzuki 70–140 HP — 15-Spline RH with Brass Bushing, Corrosion-Resistant

If your Suzuki outboard falls within the listed models and years, this Boatman propeller offers the same diameter and pitch as the factory unit so you can swap it in without modification. Built from a high-strength aluminum alloy with a brass bushing and factory surface coating, it’s intended to deliver stable performance, reduced drag, and corrosion resistance compared with untreated cast parts.

Will this propeller fit my Suzuki engine and gearcase?

This propeller is made to match specific Suzuki outboards—confirm the gearcase size, spline count, HP range and production year before buying. It fits a 4.25" gearcase and is compatible with the DF50, DF60, DF70, DF90, DF100, DF115 and DF140 variants listed for the stated years.

• Diameter: 14 inches; Pitch: 19 inches
• 15-spline shaft connection; right-hand (RH) rotation
• OEM reference number: 58100-90J10-019 for cross-checking
• Check your engine model and production year against the included compatibility list

How does the Boatman propeller affect speed, handling, and fuel use?

The 14x19 sizing balances top speed and load carrying for the specified 70–140 HP range. Because the blade profile and surface finish are engineered to reduce drag, expect smoother acceleration and steadier cruise compared with worn or mismatched props. Exact fuel impact depends on boat weight, load and engine tuning.

• Smoother blade surface reduces water resistance for more efficient cruising
• Three-blade design favors a compromise between acceleration and top-end speed
• Same diameter and pitch as factory parts to maintain designed engine load

What materials and construction features improve durability?

This propeller uses a high-strength aluminum alloy and a brass bushing, produced with an extrusion die-casting process and a protective surface coating. Those choices help resist corrosion and wear in the marine environment while preserving shaft engagement and blade geometry over time.

• Aluminum alloy body for light weight and impact resilience
• Brass bushing for secure spline engagement and reduced wear
• Protective coating to slow corrosion and extend service life

How do I confirm I’m ordering the correct replacement prop?

Before purchase, verify four key measurements from your current propeller and engine documentation: diameter, pitch, spline count and rotation direction. Cross-reference your engine’s HP and production year with the compatibility list to ensure a proper match.

• Measure hub spline count (this prop uses 15 splines)
• Confirm rotation: this is a right-hand (clockwise) propeller
• Compare OEM part number 58100-90J10-019 if available

Who this is for: Boaters who need a reliable, factory-size replacement prop for Suzuki outboards (70–140 HP) and prefer a cost-effective aftermarket option that mirrors the original diameter and pitch. It’s suitable for owners restoring lost performance after prop damage, replacing corroded units, or keeping a spare on board. If your engine model and year appear in the compatibility list and you require a 14x19, 3-blade, 15-spline right-hand prop, this Boatman unit is designed to fit and perform in those installations.
