Comments Off on Centurion vs Malibu – Fuel Consumption 2
This video is a follow up to the video that we made comparing a Malibu MXZ and a Nautique G23 to a Centurion Ri257 looking at fuel economy and power. If you would like to check them out you can see each of them here:
There were a number of people that were concerned that the information wasn’t valid because the Malibu MXZ we used in the video was a 2016 model and the 2017 model changed both the hull and the drivetrain of the boat. As you can imagine, getting current model boats to do this kind of testing is difficult, REALLY difficult. We made the offer to run our fuel flow rate Diacom test on any manufacturer’s current model year towboat, but had no takers.
Well, it didn’t take long for us to take a 2017 Malibu 24 MXZ in on trade for a new Centurion. Of course, we couldn’t miss [...]
Comments Off on Centurion vs Malibu vs Nautique Fuel Economy – True Test of the Opti-V Hull
If you’ve spent much time looking on our website or poking around online you’ve probably come across some pretty unbelievable information about the new Centurion Opti-V Hull. We made this video because the claims about the Opti-V hull are exactly that – almost “Unbelievable”.
I mean, come on… 50% better fuel efficiency? A better wakeboard wake than the best wakeboard boats on the market? Faster acceleration than a flat bottom boat?
Yes, and this is where we prove it.
Earlier this fall we took out 3 boats – a Centurion Ri257, Nautique G23 and Malibu 24 MXZ, hooked a diagnostic computer up to them and got the raw data on fuel economy, acceleration speed, noise rating, etc. Big thanks to our friends and team riders for letting us use their boats to do these tests! If anyone has a comparable boat from a different brand let us know and we are happy to do this [...]
Comments Off on Surf / Ski / Wakeboard – One Boat – 5 Minutes!
In this post we have a video that we shot doing something we have never seen done before. We are showing you the surf wave, wakeboard wake and ski wake behind the same boat – all in one take; completely unedited, untouched and shot on an iPhone7. This hopefully shows you the performance of the new Opti-V hull as well as the speed and versatility of the Ramfill ballast system.
When showcasing the “crossover” performance of other wake boats you typically see something like this: -The ski wake with one driver, no passenger, and no ballast. Typically these are shots of the skier outside the wake and never showing the skier going through the wakes. -A different set of shots of the wakeboard wake with 8 passengers, full ballast and a pro rider with camera angles designed to make it look bigger and cleaner. -Another set of shots of the surf wave [...]
Comments Off on Utah Surfest Wakesurf Boat Reviews
On June 24-26 we had the opportunity to participate at the Utah Wake Surf Fest. This is a fantastic event that allows people to surf on and review surf boats and waves from nearly every boat manufacturer. The best part for anyone reading this is that the results of the event, including detailed scoring of every aspect of the boats tested, is published for everyone to see. In this article we are going to break down the reviews for each boat and take a closer look at what people thought about each of the boats.
THE EVENT Before jumping into the details, it is important to understand how the event worked. A total of approximately 30 riders tested a number of boats and boards at Jordanelle reservoir, getting to spend approximately one hour surfing behind each boat over 2 days and spending considerably more time hanging out inside the boats while others were surfing. [...]
Over the past few years we have seen a whole bunch of “Surf Systems” hit the market. With so many options to choose from, a lot of people are left asking, “Is one better than another?” In this post we want to talk about the systems, what makes them different, and to try to cut through the marketing rabble to take a serious look at how they compare. I am going to apologize in advance; this topic gets pretty deep, and covering it is necessarily long. So sit back, grab a drink and forgive me for taking up a chunk of your day – I will do my best to make it worth your while.
Before we jump in, it is important to note that you should take some of the information with a grain of salt because we are not just comparing the systems, but comparing the systems on the boat that they are [...]
You know those yellow stickers on the boats that say something like “16 Persons or 2350 lbs?” One of the most common questions we get is, “Is ballast factored into those numbers?” or, in other words, “How many people is the boat rated for when the ballast is FULL?” This is an important question – probably more so than you might expect.
First, let’s talk about those ratings and where they come from – bear with me, this will all come together here soon. Most people think that those ratings are established by the Coast Guard,; however once a boat goes over 19 feet, the Coast Guard no longer gives specific ratings for capacity. The capacity ratings are, in most cases, established by a body referred to as the National Marine Manufacturers Association (NMMA). The NMMA is a governing body that ensures that boats built by participating manufacturers are up to certain safety standards, one [...]
Over the past several years I frequently hear the comment from potential boat buyers, “My family and I want a boat mostly to wakesurf behind, but we are not professionals so we don’t need a pro surf wave.” Well, I can say, from personal experience teaching hundreds of people to surf, that this idea is a misconception. I do agree that for a beginner to intermediate level wakeboarder’s perspective (90+ Percent of people), a professional level wakeboard wake is too big, very intimidating and limits progression. However, for a beginner to intermediate level wakesurfer’s perspective, a “professional-level” surf wave leads to much easier and overall much better experience. With the right wave progression is much faster, and easier. In fact if you weigh over 190 lbs. learning to really surf (throw in the rope and ride) is just about impossible without a good quality surf wave .

There is No Replacement for Displacement.
We are often asked why Centurion boats create such awesome surf waves. There are multiple factors that combine together to make a world class surf wave, one of which is experience. Centurion created its first surf boat hull way back in the 1990’s, way before surfing was the cool thing. Additionally, there are things like CATS, Quicksurf and trim tab shapes that allow for wake customization and tweaking. But the most important factor, by far, is displacement. There is no replacement for displacement.
What do I mean by this? Well, it’s simple; physics really does matter. There are natural laws that apply to wave/wake size and shape. The wave or wake of your boat (what you surf on) is created by your boat displacing water. So, in basic terms, with all things being equal (the hull shape, size, etc. of the vessel), the boat and ballast combination that weighs the [...]
Ever since PCM came out with the new direct injection H5 and H6 engines, we have been asked what the difference is between direct and sequential injection and if PCM is the only company using direct injection. I hope to answer both questions below. Here is some basic information about injection systems.
Basically, a SFI (sequential fuel injection) system has a fuel injector for each cylinder. Each of these injectors puts fuel into the system at 30-40 PSI before the intake valve. This air/fuel mixture is pulled into the cylinder past the intake valve on the intake stroke of the piston and is then compressed and ignited. This system was way more fuel efficient and created way more power than the carburation systems it replaced. Sequential fuel injection has been used in marine engines for several years and is the system that is currently used in most new towboats [...]
