Sea-Doo fully chargedThe 2015 boating season is fast approaching and Sea-Doo owners are preparing for a full summer of family fun on the water. As you are taking your beloved Sea-Doo watercraft or boat out of hibernation there are some technical aspects that Father time may have had his way with over the past few dormant months. Your battery is where it all starts (or doesn’t start) and batteries can and do lose their ability to maintain a charge over time. But, there is another crucial component that can also lose its charge, your mandatory fire extinguisher.

The beginning of the season is the time to check both of these essential items as both your Sea-Doo watercraft battery and fire extinguisher can lose their charge over the winter months of inactivity. Regardless of age, your battery should be given a full charge as step one in pre-season prep.  Be sure to remove the battery from the PWC to avoid gas fumes and possible fire, and set it on a cleared work bench. Connect a battery charger to the battery and let charge over night (please refer to owners manual for exact charging procedures).  Most modern battery chargers include “fully charged” indicator and this indicator should inform you if the battery is accepting the charge  – meaning the battery is still good – or not. If the battery is not accepting the charge or holding the charge and shows signs of being weak after a 6+ hour charge, it is time to replace it with a new Sea-Doo specific battery from an authorized BRP/Sea-Doo dealership. Be sure to bring your old battery with you to your dealership so it can be properly and responsibly disposed of.

Every PWC, including Sea-Doo watercraft, must carry a fully charged fire extinguisher onboard at all times. This is for not only your safety but potentially the safety of others.

Sea-Doo Fire ExtinguisherBut you may ask, “why?” Why do I need a fire extinguisher on a watercraft when I am going to be surrounded by water? That is a fair question. The answer is you never know what can happen during a day of boating. If something were to happen where there was an open flame while you were riding you would be able to extinguish it. Having a fully charged fire extinguisher on board can also be very helpful when encountering another vessel with an open flame situation. The Coast Guard and local boating law enforcement agencies check fire extinguishers to ensure they are up to date and fully charged. The best rule of thumb is, if your fire extinguisher doesn’t have an actual pressure gauge, is to replace it every year.

Sea-Doo Safety KitAnd while we are discussing safety the Sea-Doo Safety Kit can also help you in, or out of, an unexpected situation. In case your friend didn’t replace his older battery, the kit includes a whistle that he can use to let you know he needs you to tow him back to shore with the buoyant 50′ nylon rope that is also included in the kit.  The Sea-Doo Safety Kit also includes a flashlight to help inspect the engine compartment and the container can be used as a bailer.

These three items should be first on your To Do list when preparing your Sea-Doo for the coming season and all three products can be purchased at an authorized BRP/Sea-Doo dealer. Check the Doctor Doo column of OnBoard for regular maintenance, service, and DIY tips to ensure you get the greatest reliability and most fun from your Sea-Doo watercraft.

DOCTOR DOO – HOW TO KEEP YOUR SYSTEM CLEAN – DON’T SUCK!

Doctor Doo is here to help cure what ails you!

A problem we hear from time to time with Sea-Doo watercraft and boat owners is the congestion of debris in the direct drive water jet propulsion system but this is something that can be minimized with some understanding of what is going on underneath your vessel.

Lets first look at what a Direct Drive Water Jet Propulsion system consists of.

A Direct Drive Water Jet Propulsion system starts at the intake, this is a tunnel or track that enters the bottom of the hull to feed the encased impeller. Now hold this vision for just a few sentences… In front of the intake inside the vessels engine compartment rest the engine, mounted directly onto the bottom of the hull with the in-line drive shaft angled straight back (towards the transom) traveling through the hull and connected to the front, center of the impeller. No transmission here, it is a “direct-drive” system.

Okay back to the water flow. The impeller is a bladed or veined component that when turned transfers water from front to back, this is what creates the water propulsion. But there is more to it than that, behind the impeller blade are directional veins angled the opposite as the impeller blades to straighten the twirling water flow to force it straight back to use that energy as efficiently as possible to create maximum forward thrust. Behind the jet pump is the Venturi. The venturi is shaped similar to a cone, with the inlet being much larger in opening diameter than the smaller, tighter exiting outlet. This compresses the water and provides greater thrust when forced out. Imagine holding a garden hose with water running freely out of the end. now squeeze your thumb over the end and wow, it shoots a stream of water a lot harder, faster and further, this is what the venturi does.

Now to provide steering (and trim on some models) there is a pivoting nozzle on the rear of the venturi, this redirects the water flow from side to side to push the transom to side to side to change direction – or up and down to change/trim planning angles.

Okay so that is direct-drive water jet propulsion 101, this video offers a visual look at everything we just described.

This system draws water up into the water jet pump and pushes it out the back to propel the vessel. The pump is creating suction to draw that water into the system and anything else that might be in its negative pressure proximity. This could include sand, trash bags, sticks, Sunglasses, rope, but designed to efficiently process water and it does this very well. To help ensure only water enters the system an intake grate is mounted over the inlet. This is usually comprised of three hydrodynamically designed “bars” that run from the front of the opening to the back and are nearly flush with the bottom of the hull. The intake grate ensures large objects do not enter the propulsion system.

The intake grate is designed for hydrodynamic performance and the greater the covering, fencing or screening of the intake substantially impedes water flow and ultimately performance suffers. There is a balance but with this small objects can be drawn into the intake system. Here is where education can save you headaches.

First you should always follow your owners manual and operate your vessel in 3-feet (1m) of water depth or more but if you do find yourself in shallower water and your Sea-Doo vessel’s propulsion seems “funny” get to a safe location (one with out current and clear of potentially dangerous objects) and turn off the engine(s). The worse thing you can do is try to power through it. Why? Okay, imagine you’re vacuuming the interior of your car. You accidently run the hose nozzle over a rouge gas pump receipt and it is sucked to the end of the hose impeded airflow. Bumping up the vacuum power to max only holds the paper to the hose tighter. Shut the vacuum off and watch the paper fall off the vacuum hose un aided.

A common mistake of Sea-Doo owners that get into vegetation and it begins entering the jet pump system is powering up and hoping it will be processed. What this can do is pull the debris into the system deeper increasing the odds it will get stuck. Another common mistake is thinking by putting the vessel in reverse and powering up it will blow out the debris that way.

Remember a few paragraphs up when we discussed “direct drive”? This system works off of redirection of waterflow. In reverse the water coming out of the venture is redirected forward, similar to technology of jet airplanes when they slow down after landing.  The intake is still drawing in water in the same direction even when in reverse.  Both of these actions can also cause the exhaust to overheat as the cooling water flow is hindered. The best course of action is to turn off the engines and more times than not the debris will simply fall away.

In 2012 BRP takes this thinking a step further with the addition of the weedless system. This new system works with the iTC (intelligent Throttle Control) system and offers a button located on the dashboard of select Sea-Doo boat models and when activated (engine must be turned off) hinges the intake grate downward to utilize gravity in the aid of debris simply falling away.

That was a long way of simply saying, to keep your propulsion system clean, simply suck less!

 

 

This installment of Doctor Doo was supplied by Willy Carmine a former member of the BRP/Sea-Doo R&D team and current President of Route 1 Motorsports an authorized BRP Sea-Doo and Can-Am dealer in Grant, Florida where his customers boat in the Indian River, the 120 mile long lagoon that averages 4.5 feet (1.4m) in depth, so he knows a thing or two about shallow water boating.

 

DOCTOR DOO – Winter Storage, Old Man Winter Will Find Your Sea-Doo!!

WHY WINTERIZE, WHY, WHY, WHY?

Should I winterize?

Do I NEED to winterize?

Well then, what IS winterizing?

Is a SNUGGIE, LL BEAN and a can of Sterno involved in any way?

If you live in the tropics as we do in sunny South Florida , you may think winterizing is just for our northern friends who make a snow shovel standard morning equipment. Nope, winterizing can easily apply to us all. Not necessarily for all of the same reasons though. This is why we like to call it winter “Storage” more than winterization.

Many of us hardcore riders will ride year round as long as our choice riding spot is still *liquid* and with the southern regions of North America feeling the first truly cold spell of the season, this is now very pertinent. So it’s really all about proper storage, and will vary depending on temperature exposure, weather, duration of storage, etc.

Many negative implications can result from improper storage, ranging from gummed-up fuel systems, prematurely failed batteries, rusted precious internal metals to actual broken engine cases, and other areas with cooling jackets. Instead of yet another article on “How to Winterize” this one is to warn you of the results of not taking storage seriously.

Take proper storage seriously and the cost of keeping your favorite Sea-Doo in top shape will be much lower. Going through the proper motions is also key to keeping our machines at peak performance. The kind of performance we have grown accustomed to from our friends at BRP! So to get down to the basics, if you are in an area that gets into the lower 30 degree range, full-on winterization is a must. Even down in the south we saw major problems last winter with expensive internal engine freezing issues that could have been avoided.

Some individuals are able to do this on their own, but if you are in any doubt get your watercraft or boat to an authorized BRP/Sea-Doo dealer ASAP! There you’ll find the right tools, technicians with knowledge and products that go into proper storage procedure and ensure it is performed correctly. Here you can be assured the right chemicals, the right tools and technicians armed with the latest tech updates from BRP engineering are utilized to ensure the best preventive maintenance is performed.

BRP offers premium storage lubricants in the XPS brand and additional maintenance items available at authorized BRP/Sea-Doo dealers

The owner’s manual touches on the big points of storage, but the large amount of batteries that we sell and the fuel systems that we clean show us that a little $$ spent now, on the right things, (Battery Tender or Fuel Stabilizer Stabilizer for example) sure can save you LOTS of the green stuff in your wallet, or maybe, just maybe, that next upgrade to your vessel that you’ve been wishing for!

Have a beautiful winter, and keep up with us at OnBoard

Long may you run, Dr. Doo
