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 [...]

Do I need a Pro Level Wakesurf Wave

Wakesurfing is easier and more fun with the right wave!

Do I Need a Pro Level Wakesurf Wave?

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

Building The Worlds Best Wakesurf Waves.

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 [...]

Direct Injection vs Sequential Fuel Injection

More Torque and Less Fuel - PCM Direct Injection Engines

Direct Injection vs. Sequential Fuel Injection

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 [...]
