Solas Acme Propellers: Precision-Engineered for Inboard Performance

When inboard ski, wake, and surf boat owners demand the most from their propulsion, Solas delivers through its extensive lineup of Acme propellers. The intersection of Solas’s world-class manufacturing heritage and the Acme line’s inboard-focused engineering creates some of the most capable tournament and recreational stainless steel propellers available today.

A Legacy Built on Engineering Excellence

In 1985, Dr. Solas Y. J. Lin set out to create world-class components for boats and personal watercraft, building the manufacturing plant to the strictest standards. Decades later, that founding commitment to precision is still the backbone of every propeller Solas produces. All Solas propellers are developed through a state-of-the-art process — encompassing theoretical calculations, geometry design, prototype testing, pilot production, and field tests — ensuring each prop is dialed in before it ever reaches the water.

Why Solas Excels in the Acme Propeller Category

Solas tournament ski boat propellers are designed specifically for inboard applications, resisting rust and maintaining high blade stability due to the industry’s highest percentage of chromium, nickel, and molybdenum. Thanks to revolutionary blade geometry, they handle a wide range of conditions from recreational skiing to competitive events.

Solas stainless steel propellers are produced via an investment casting process , which offers an impressive degree of accuracy, ease of repeatability, versatility, and component integrity — allowing the creation of complex shapes that would otherwise be impossible. The result is a propeller blade with tighter tolerances, superior surface finish, and more consistent performance across the entire pitch range.

Materials and Durability Built for Demanding Use

Solas stainless steel propellers contain the largest percentage of molybdenum, nickel, and chromium in the whole industry. This purposeful blend of metals makes the propellers incredibly resistant to rust despite constant exposure to saltwater and allows the blades to run in a more stable manner. For inboard boats that spend seasons on fresh and saltwater alike, this corrosion resistance is a critical advantage.

Two foundations set Solas apart: a unique casting process that yields stronger, thinner, and smoother blades, and specially designed rubber-molded octagonal hubs that increase vibrational absorption and reduce slippage. On an inboard ski or wake boat where smooth power delivery and responsive handling define the on-water experience, these engineering choices are anything but incidental.

Broad Selection for Every Inboard Application

Solas offers over 1,400 blade choices for recreational boats ranging from 2.5 to 350 horsepower outboards, inboard/outboards, or competitive ski inboards. Within the Acme category specifically, this breadth of selection means boaters can find propellers precisely matched to their hull, engine, and intended use — whether that’s slalom skiing, wakeboarding, or general tow sports.

As an additional precaution against corrosion, Solas propellers are treated with up to four layers of performance paint through a sophisticated process ensuring even coating and 100% surface area coverage. Quality control subjects these propellers to more than 500 hours of abuse in a saltwater spray tank — equivalent to over half a year of regular saltwater exposure.

With 447 products available across the Acme line, Solas offers one of the most complete inboard propeller selections on the market. Explore the full Solas brand catalog or browse all Acme propellers to find the right fit for your boat.
