I want to extend a sincere thank you to the people at www.ptpropeller.com (Olympic Propeller Company) for their help, considerable knowledge and vast patience. In a world of online retailers where some could take advantage of your misfortune to expand their profits, it’s great to find a customer service company that happens to sell what you need! After reading online about so many people in frustrating searches for a propeller that would work well on their single engine catamarans, I had prepared myself for a painful experience to find one for mine. The 60HP Honda motor and prop that I had was from an inflatable boat that I had upgraded from, and the manufacturer of my new 17 ft. Twin Vee Catamaran wasn’t a Honda shop and couldn’t make a recommendation on a prop for the motor I had. So, after getting massive ventilation with the existing prop at 3500 RPM’s, I looked into the four blades Power Tech which had received strong recommendations from several cat owners online. Well, the prop showed up on a Monday and for the next month small craft advisories on weekends were the norm and I couldn’t do a sea trial. I called and before I could even finish explaining my dilemma, Jeff said “Don’t worry about it.” When the weather broke, I got in my sea trial, and although things were much better, I had overestimated the pitch and another prop was needed, problem was I had a planed vacation to Key Largo in five days and didn’t want to risk having no prop for my boat. They let me place an order for the exchange prop that I needed and rushed to make sure that I would get it in time for my trip. The prop showed up only hours before I left, but I swapped out the props and it turned out to be the perfect prop for my boat. When I got back from my trip, almost two months after buying the first prop from them I sent it back for a refund less the exchange fee. From beginning to end, I couldn’t have asked for more knowledge patience or understanding on their part. I tend to do a lot of research and had an idea of what I needed, but it sure is comforting to have an expert talk you through it. To anyone looking to put a Honda BF60 on a Twin Vee 17ft. I suggest the SWC4R with 11” if you will run heavy or 12” if more of a tender.
