Need more than one reason to know who the leader is? We have FIVE reasons OJ continues to lead the pack in inboard propeller development, introducing OJ’s latest innovation, TZ X-5, the first wake boat specific 5-Blade inboard propeller.

Building on the success of the large diameter XMP EDGE propellers, we teamed up with Travis Moye and Zane Schwenk to develop this revolutionary 5-Blade propeller. Travis, a world class driver and boarding instructor, and Zane, one of the best all around skiers and boarders in the world, provided crucial insight and expertise in the development of the new 5-Blade, hence the aptly named TZ X-5 was born.

The TZ X-5 provides unrivalled low end power and consistent RPM under the most extreme loads. Want to sack out the boat? Not a problem with the TZ X-5. Strong on power and more efficient under load than any other prop out there.

For 75 years OJ PROPS has been an innovator in the propeller world. For the past 35 years we have solely concentrated on the inboard tow boat market. Over the years we have introduced many firsts to the market that continue to shine today. First 4-blade propeller specifically designed for tournament tow boats, FORCE 4-Blades. First to develop a propeller specifically for the heavily weighted wake boats, the large diameter, low pitch XMP EDGE line. With the TZ X-5, we continue to set the pace others are sure to follow, again


XMP Edge

The XMP EDGE was developed for the hardcore wakeboarders and skurfers. The XMP EDGE is the first propeller in our industry designed specifically for the V-drive wakeboard boat and offers a larger diameter with lower pitch to better handle the additional ballast added to the wakeboard boats providing overall performance that is unrivaled. While the XMP EDGE propeller concept has been copied it has not been matched with performance. The XMP EDGE line continues to grow and is offered in many different sizes to fit your specific needs.



The XMP, an eXeptionally Machined Propeller. The XMP is OJ’s fully CNC machined propeller line combines our 75 years of propeller development with the CNC machining process. The XMP propellers are crafted from highly accurate Ni-Bral castings in our foundry and fully machined in our CNC machining centers. The XMP propeller line boasts a new refined design based on our original LEGEND propellers. The highly accurate CNC machining process produces propellers that are accurate and consistent from part to part. A reliable and repeatable performer defines OJ’s XMP PROPELER line. The XMP line offers propellers in both 3 and 4-blades.


Force 4-Blade

Like it’s predecessor, The LEGEND 3-blade, The FORCE 4-BLADE is a strong and affordable performer. The FORCE 4-Blade was the first 4-blade introduced that provided the tournament tow boat a strong, exceptionally smooth and steady pull.


Legend 3-Blade

The name speaks for itself. The original LEGEND is a design handed down from the originator, Oscar Johnson. This hand crafted 3-blade has been a consistent performer for many years. The LEGEND 3-blade is still a popular choice for its performance and affordability.


XPC Shaft Seals

XPC and DLXPC Seal Systems – Comprised entirely of a Glide – 100 bearing made in the U.S.A., making it very durable, light weight and non corrosive. The light weight housing also reduces the loaded weight on the shaft and seal, resulting in a better performing and longer product life.

The integrated bearing surface allows the seal to run true to the shaft. Our proprietary double lip seal uses no mechanical springs and does not harm the shaft over time, even if it is run dry! The water provided to the seal system is only required to insure a properly lubricated bearing surface when a slight load occurs due to difficult alignment.

The DLXPC Seal is a revolutionary design that provides an integrated spare seal carrier. This system can be serviced in under 5 minutes and you’re on your way! Gone are the days of flooding the bilge to change a seal or the costly expense of a haul out to do such job.

Durability is not an issue. With proper alignment and lubrication the XPC Seal System has proven successful in Hydroplane race boats running shaft speeds in excess of 6000 RPM for over two seasons!

The XPC Seal is the standard for the recreational boat enthusiast. Used widely in the Ski and Wakeboarding industry XPC Seals perform like no others, providing years of worry free boating at an economical price.


Strut Bushings

Long wear life

Vesconite gives up to 10 times the service life of phosphor bronze in poorly lubricated conditions.

Vesconite keeps size – no water swell

Vesconite does not swell. Vesconite is one of the most dimensionally stable synthetic materials available. Vesconite bearings may be machined to the correct clearances without fear of swelling. Clearances do not disappear. Vesconite gives you security!

For most synthetic bearing materials, water swell is a major problem. With water swell, there is always a risk of seizure. To compensate, suppliers of materials which swell advise excessive

Smooth Running

Compared to most elastomers, rubbers, nylons and laminates, Vesconite has a low friction. Many products are claimed to have a low friction, but often only in the laboratory when tested under lightly loaded conditions, and before the effects of softening caused by water. Vesconite keeps its low static and dynamic friction whether dry or wet, or lightly or heavily loaded. Why is this important? Low friction for a bearing means less bearing wear, as well as smoother operation and less wear to the whole running gear.

The low static friction of Vesconite is especially beneficial to the low amplitude oscillating movements of rudders. With Vesconite, every change of direction occurs smoothly, with a minimal power requirement and without any jerking.

Test this for yourself with Vesconite – its the best way to prove it. You will be delighted with the performance improvement compared to conventional materials.

SOS: Save Our Shafts

Vesconite saves your shafts. Because of its low friction, most users report greatly reduced wear rates on shafts and liners. In many applications, users have switched to Vesconite because of the reduced wear, increased life and savings obtained on their shafts, often a very expensive component.
