About SBT

Greg Pickren founded SBT, Inc. in 1997 and built the company to become the largest supplier of aftermarket jet ski (PWC) parts in the world. Mr. Pickren, at the time a seasoned industry professional in theautomotive parts business, was intrigued by the fact that there were no suppliers of remanufactured engines for PWCs. After studying the intricacies of the PWC market, SBT was launched. Although Mr. Pickren was not a PWC expert at the time, the concept would mimic what had been done for decades in the automotive business - high quality remanufactured engines for a fraction of the price of new engines. With little fanfare, a factory was built and the groundwork was laid for what would become the largest PWC aftermarket parts company in the world.

In it's's first year of operation, SBT remanufactured over 2,000 engines.Over the next four years, the company quickly grew to over 10,000 engines per year. In 2005, the company transitioned from an engine only company to a full line supplier of parts. Today, SBT is to the PWC market what NAPA and AutoZone are to the automotive market.SBT boasts a product offering of over 5,000 parts for Sea Doo, Yamaha, Kawasaki, Polaris, Tigershark and Honda watercraft. SBT's dealers and customers are worldwide with orders coming in every year from over 177 countries out of the 196 on the globe.

The company's 70,000 square foot factory and headquarters are located in Clearwater, FL. Mr. Pickren still owns SBT and is involved in managing the direction of the company.

Because you can judge a boat by its cover!®

Thus, the first world’s first universal-fit aftermarket wakeboard tower was born and appropriately named MT1. It featured double header bars for ultimate structural support and additional mounting space for accessories. The tower legs could be moved forward or aft to accommodate the shape of the boat or to afford additional headroom. The MT1 still enjoys enormous popularity today as one of the most versatile and reliable universal-fit wakeboard towers available as evidenced by the hundreds of accolades and photos we’ve received from happy customers around the world.

However, being engineers, the work was just beginning. The team decided to expand to include accessories that would improve the functionality of the tower – including racks to keep the decks free of boards, driver mirrors to view those in tow, and of course awesome wakeboard tower speakers to crank up the volume and the fun. 

Monster Towers are designed to be easy to install so you can do it yourself or rely on one of hundreds of capable Monster Tower dealers around the globe. The idea is that Monster wants you spending time enjoying yourself, not tweaking and adjusting your tower after every ride. 

More than a decade later, with hundreds of accessories and a wide array of towers, the team at Monster Tower remains committed to delivering universal- fit products of solid quality for an affordable price. In fact, each tower is back by a guarantee that says, "If you don’t LOVE your Monster Tower, we want it back!"

Fishmaster was created to provide innovative and affordable products to fellow fishing addicts. It began in the Spring of 2005 as a team of seasoned engineers who had designed the most popular wakeboard tower set out to build the first universal t-top that could fold for fixed bridges and storage. This quickly grew to a team including other engineers, professional fishermen and boat dealers providing input from every perspective - installation, ownership, design, structural analysis and manufacturing.  The team had one common goal - create a great T-Top and make it affordable.

We then set our sights on providing a complete line of accessories for the Fishmaster T-Top including swivel rod holders, innovative soft goods storage products and many others.  We are currently working on my new products and accessories for fishing boats that each have innovative functionality and are affordable.

Our goal is to have 100% customer satisfaction.  It is not acceptable to us if any customer that owns our products are not completely satisfied.  If you own a Fishmaster product and are not 100% happy please contact us, our job is not done yet!

We thank you for your interest in Fishmaster and look forward to the opportunity to provide you outstanding service and support.

Sterndrive Engineering spent two years doing research, design, development and testing before introducing its stern drive in 2004. Sterndrive Engineering operates one of the only private research lakes for marine product testing in the country. All of the component parts were tested extensively on a stationary dock enduring hundreds of hours of run time. "Our gas bills were staggering, even back then,” says Pickren. "Run it 'til it breaks was our motto."

Stern drive gears are by design some of the most over stressed gears in the world. Using the most advanced technology and materials is critical. While Sterndrive Engineering's gears are made in Asia, the 4820 steel alloy used a rather unique alloy. There are Japanese alloys that are similar, but none of them have the hardness and durability features that are needed for our gears." Sterndrive Engineering's gears are also shot peened and cryogenically treated. Both of these technologies add significantly to the life of the gears. "As far as we know, we are the only company cryogenically treating sterndrive gears." says Pickren.

Sterndrive Engineering has quickly become the largest supplier of aftermarket stern drives in the world. Pickren proudly remarks "Almost every day a customer tells us thank you for saving him over $1,000 and getting his boat running again. It's this kind of feedback that gets us excited about what we do.”

Mission Statement

SEI's mission is to make owning, operating and maintaining a stern drive more affordable.

3 Year Fault Free Warranty

Simply put, buying a remanufactured drive is risky.

Common practices in the industry include reusing critical wear parts such as cases, gears, shafts and bearings. Inspecting these parts to determine a reasonable expected remaining life is nearly impossible. Consequently, premature failures are common.

Why risk relying on used and possibly worn out parts when you can buy brand new drive a from SEI for less money?

Sterndrive Engineering has spent 18 months and 10's of thousands of dollars on product testing at the company's private research lakein Central Florida. The result is a drive that we can say with 100% confidence works. Add that to our three-year warranty and it's easy to see why SEI is quickly becoming the largest supplier of replacement drives in the world.

SEI's warranty is the best in the industry for anyone considering purchasing a new drive. 3 Year Fault Free Warranty
