Wakesurf Boats

Wakesurf Boats

Wakesurfing is becoming a popular watersport activity.  Google trends indicates wakeboarding popularity (based on google searches) has dropped by nearly 70% from its July 2006 high.  Wakesurfing, on the other hand, has doubled in google searches during that same time frame.  was virtually.  While wakeboarding still has a greater search volume, boat manufacturers have just recently begun to focus significant efforts toward wakesurfing enthusiasts.

Malibu (including Axis), Mastercraft, Skier’s Choice (Moomba and Supra), Centurion and nearly all other inboard manufacturers have incorporated surf wave making devices into the lineup.  And, up until recently, they’ve had a lock on the market.

Since wakesurfing involves riding a small surfboard directly off the stern of the boat, inboard boats seem to be the only practical boat for wakesurfing.  Stern drive boats and outboard boats have large outdrives and propellers hanging beyond the transom.  This places the wakesurfer at significant risk of serious injury or death if they fall.

Recently, Bryant has attempted to enter the wakesurf market by offering a sport porch on several of their models.  The sport porch is an extended swim platform that fully covers the boat’s out-drive.  While this helps prevent injury, it also adds significant length to the boat (a possible concern for storage), has an unusual appearance and isn’t a comfortable area for lounging.  It’s also an expensive option (a little over $4,000 on the 233X model).

Several sterndrive boat manufacturers including Regal, Cobalt,Four Winns, Monterey and Chaparral have indicated they may begin incorporating Volvo Penta’s new forward facing outdrive (also called a tractor drive) in hopes of capturing some of the wakesurf market.  Unfortunately, while they place the propeller in a more protected location, still leave a large, heavy, metal portion of the outdrive aft of the transom.  While hitting the outdrive portion is certainly better than hitting the propeller, it’s still going to put a dent in your day – not to mention your forehead.

Bryant may be acknowledging that inboards are inherently better suited for wakesurfing by announcing a new sub-brand of boats called: “Wake Tractor”.  While not much has been officially released, scuttlebut has it these will include Crusader engines which have historically been inboards.

If you’re looking to get into wakesurfing or if you’re looking to improve your gear, the next few years may be the perfect time!  For serious wakesurfing enthusiasts, check out the latest offerings from Moomba, Supra, Malibu, Nautique, Mastercraft, Centurion, MB Sports and Bryant.

What do you think?  Would you surf behind a sterndrive boat?

Winterizing the 2013 Moomba Mobius

Winterizing the 2013 Moomba – Part 1

Draining the water out of the hoses and engine block.

To winterize the 2013 Moomba takes some physical agility and a little knowledge of mechanical tools like using a screw driver and ratchet set! Really it is fairly easy once you see how to do it.

You will:

Remove 6 clamps holding hoses that you have to drain (8 if you have a heater installed on the boat). Take out 2 stopcocks on the engine block to drain.


Tools you will need:

Rachet Set

Flat head screwdriver


Hair dryer with heat setting

Optional: Air compressor



Step 1 – Open the back hatch of the boat to expose the engine block. Open the side walls by twisting the small clamp on top of the walls so it falls open. Reach under the block to find the bolt pictured below on either side of the block. Using the ratchet loosen the bolt, remove it and let the water drain out of the block. When the water has drained out, screw the stopcocks back on and tighten with the ratchet.

Step 2 – Under the back seat, take off the engine cover that sits under the back seat and set it aside. There is one hose (see arrow #1) that is connected like a garden hose and another hose (see arrow #2) with a clamp that needs to be loosened using a flat head screwdriver. Open these hoses up and drain the water out. When all the water is drained, tighten them again.

Step 3 – In the port quarter engine compartment you will find a slanted C shaped pipe that needs to be drained. There are clamps at the top and the bottom that attach the hose to the engine block. With a flat head screwdriver, loosen only the clamps that are closest to the engine block on both top and bottom. Pull the pipe off and drain the water. Reposition the pipe, making sure it is tight against the block again. Tighten the clamp as it was originally.

Step 4 – On the starboard quarter of the engine compartment there is another C shaped pipe that needs to be drained. Loosen the clamps and drain. Reassemble.




That’s it!  Unless you have a heater—-


Winterizing the Heater System:

The secret tool for the job: The blow dryer!

To winterize the heater system you’ll find there are two clamps on either side of the hose that leads to and the heater and back to the engine block.

See the picture below for location of the upper heater hose and the lower heater hose on the port quarter of the boat. Using the flat head screw driver, loosen the clamps on either side and slide them down the hose.

The ends of these hoses can be very difficult to pull off the engine block attachment. Using a blowdryer, set on the hot heat setting, heat up the hose for a few minutes and it will slide off the block much easier. The reason why the hose is difficult to get off without heating it up is that the block attachment has deep gripping grooves that hold on to the hose and heating the hose allows it to expand enough to slide off.
Once you have both ends of the hose off, take the upper heater hose and blow very hard through it. You will see the water coming out of the lower heater hose as you do this. Continue blowing until you don’t see any more water coming out and you don’t hear any gurgling water. If you don’t see water coming out but hear a airy gurgling sound, continue to blow until you hear only dry air.


An alternative to mouth blowing is using an air compressor to blow the air through the hose. This is obviously an easier, faster solution if you have an air compressor!


Slide the hoses back on. If they won’t go back on, heating the hose up with the blow dryer will make it go on easily again. Tighten the clamps on both the upper and lower heater hoses and you are done!
