Winter Checklist For Storing Your Ski

Below is a useful check list if you are not planning to ride over winter. 

It is also an ideal time to have your ski serviced if it has been more than 12 months since it has been done; put it to bed with clean, non-contaminated oil, a lubed drive line, treated engine bay and jet pump and make any battery maintenance plans such as installing a CTEK plug & play system. 

1.  Check over the exterior of your ski for any damage of summer - get right under the hull and check for any deep hull marks which may need repair/patching.  Check the seats and treat with a seat/vinyl polish (Mothers Vinyl Polish is nice). 

2.  Wash and wax/polish the hull.  As long as the craft is stored in a garage under a cover, once a year polish will keep a good original gloss on the body.  Treat bumpers and trim with appropriate polish products.

3.  Dry out the inside of the hull;  all hulls have pockets where they trap water and it can't escape.  A few cm's of water circulating in a closed hull for 6 months causes rapid extreme deterioration of the engine bay components.  If you can get a sponge into the pockets of water (such as in pole ski's) remove this way otherwise you will need to allow it to air without the seats for a few days/weeks to evaporate naturally.

4.  Stand the seat in the pointed tips (front) vertically to allow excess water to drain from the seat.  This reduces the weight of your seat and helps prevent water spray through onto a hot engine if your model has drainage holes on the underside of the seat.

5.  Spray Inox or similar product around the jet pump to prevent excess corrosion build up.

6.  Fuel;  traditionally the fuel was drained from the tank to reduce a multitude of issues, with the worst being water getting into the fuel then into the carburettors.  These days we don't have many carburetted models left, so a "better than nothing" trick is to fill the fuel tank to the top to reduce the air and condensation ability inside the tank.  Fuel naturally attracts water but if the pressure is high enough this is reduced as much as possible.

7.  Attach battery charger;  check your battery:  lead acid batteries will need to be monitored to make sure they maintain good liquid levels, AGM batteries are sealed and just require a good battery charger designed for this type of battery.  Ideally your battery charger should be a smart charger which maintains the battery if plugged in all winter.

8.  Place seat on with an air gap; allow good air flow out of the hull if possible.  Obviously if your ski lives outside this will not be ideal.

9.  Store your ski in the garage with a dust cover.

10.  Mark on your calendar to start your ski once a month for 20 seconds (no hose required) to keep internal oils circulating and lubricating parts. Here's where the winter service makes full use of fresh oils and good quantities of grease on the drive line (see above).


Yamaha NZ Festival of Freeride Event

February 26th - 27th 2016

The fourth annual NZ Festival of Freeride kicked off on Friday 26th Feb at Karioitahi Beach on the West Coast of South Auckland.  Each year has been bigger and better and this was the biggest event on the jetski calendar so far this year.  Check out the video from Yamaha NZ on the day.



Inflatable Life Jacket Warnings

Extract from the Coastal News, December 24th..

Survey results from last summer indicate a large number of boaties own an inflatable lifejacket but don't know that they need regular checking and servicing.  The Waikato Regional Councils Maritime Services team leader Richard Barnett says "Whatever type of inflatable lifejacket people wear or own, it is imperative they know what type it is, how it works and how and when it must be serviced or checked. 

Richard urges boaties to follow guidelines available on the Maritime NZ web page www.maritimenz.govt.nz/Recreational-Boating/Lifejackets/Lifejackets.asp


Battery Basics

Without a doubt, the battery on your ski can cause the biggest amount of grief during your time as a jet ski owner.  Every year we answer the same questions from owners who are not familiar with the basic science of batteries.  So lets cover a few important things;

*  Your battery takes the hardest hit over winter.  If you don't use your ski for more than 3 months it can cause serious damage to the healthiest of batteries and may require replacement. 

*  If you look after your battery seriously well, you should get 3 years of good service.

*  If you are not using your ski once a fortnight, you will need to invest in a battery charger.  We use the CTEK system at $99 - it can be left on the battery full time and has a permanant connection so you don't have to fiddle with your battery terminals when you want to plug it in.

*  Basic rule of thumb;  charge the battery overnight once a month to bring it right up to full charge (or if you have an auto charger as above, you can just leave it on).  Some ski's will drain the battery faster and require charging every 2 weeks - this can also apply to some dual battery set ups.

*  A dying battery will take on a charge and seem ok, then be flat the next day.  We generally refer to this as the capacity.  Once it has suffered damage in a discharged (flat) state or starts to get old, it will be enough to effect this capacity/ability to hold its charge.

*  Battery brands; new ski's have a genuine Yuasa battery which are the best lead acid battery. When it comes to replacement, the best way to go is a maintenance free Motobatt which are constantly improving their technology and ability to stay healthy if not in use or on charge.

*  Handy tip;  if your ski starts on a cold engine at the beginning of the day (and it hasn't just come of the charger), then you should have no problems with it for the rest of the day.  If is sounds sluggish, have it checked before you go out.


Flyboard Use May Void Warranty

We have recently been made aware that if customers are using their jetski for Flyboarding, a purpose it is not designed for, they may not be covered by the factory warranty.

Kawasaki Japan recently declined a warranty repair saying using a Flyboard causes the 'boatload' to be different from the designated 'loadline' and the cooling ability around the combustion chamber will also be reduced.

It is a timely reminded for anyone wanting to use their jet ski for competitive or slightly unusual activites such as racing, that you consult your dealer first, and if in doubt ask for something in writing. 


Yamaha SVHO Named 2015 Watercraft of the Year

Every day I get this question… “Where should I go to buy a jetski”?

While there are a number of retailers out there peddling the brands, there are few that are specialists in the PWC industry. Jetski’s are not boats and should be considered different in every aspect from the suitability of the craft to your needs, the required customer maintenance right through to the aftersales back up and ongoing servicing. Of course I would say whatever ski you end up owning you will get the best service from me but I am certainly not nationwide so the following is some of the dealers that I consider 'industry specialists' and should be at the top of your list to look.

Jetski Shopping 101

One of our most common enquiries at Ski MD comes from new customers wanting buy their first jetski.  Because we don't sell them but do work on the top 3 brands, people often turn to us for an unbiased opinion.  Here are the top 5 do's and don'ts to get you started;

1.  Go to the SMART STUFF page and read Buying Your First Jetski - this covers the basic FAQ.

2.  WINTER is the best time to BUY as demand is not high and people wanting to sell may be more negotiable.

3.  Go to http://www.jetskijunk.co.nz and establish what you will need to spend on accessories to get you started.  This is a good place to get a line up of prices on everything from life jackets to flushing fluid and because it is 100% Kiwi - it's also a good place to buy and have goods shipped to your door!

4. Go to our TOP 10 favourite models to buy (further down this page).  Noting these a very YEAR specific. Not all models of the same name were created equally!

5.  Lastly, get a pre-purchase inspection done before you buy preferably from a dealer familiar with the brand - it's no guarantee but a 99% chance of getting something that won't be dubbed "the lemon".

Here are some common mistakes we often see:

1.  Don't assume that because the ski has done low hours it will be a better buy.  It is rare but not unheard of for hours to be incorrect on imported ski's.  Also, a well serviced/used ski can be better than one which has done 30 hours in 4 years and never been serviced correctly.  Visual inspection in person will normally tell a well kept ski, ie: very clean, polished, service history in a folder, etc.

2.  We know first hand someone's idea of well serviced can be drastically different from what the factory recommends.  Find out what the service intervals are of the model you are buying and ask to see the history, or have the dealer/agent confirm regular service records. *Note, there may be a fee to request service documents and the owners permission will need to be obtained first. 

3.  Surprisingly, the most common error from buyers is not knowing what year the ski is they have just brought!  This is critical to check for problem models which fall into engine years etc.  Often we find customers are several years out!  Check the last 2 digits of the external serial tag, and at very least run the model and year through Google to check if re-occuring issues are commonly documented.

4.  "I have a model that no one will service".  Check with your local boat/jetski service centre to see what models they can work on.  For example, Seadoo have specific expensive diagnostics and not many places around NZ actually work on them if there is an issue. 

5.  "A marine shop down the road is selling it so it must be okay".  We disagree!  If a ski has been traded in but it is not a brand they normally work on, they may be honestly unaware if it is a lemon on not.  Consumers guarantee will be on your side, but it may still be a stressful situation if it turns ugly, for both parties.

Jetski Parts R Us - No Longer

We had fun starting the first online jet ski parts and accessories online store in New Zealand back in 2012 that was JetskiJunk.co.nz and we were continually amazed by the local support.  It started originally as a silent 'sister' business to Ski MD but eventually grew into it's own thing requiring dedicated staff and extra support.

Mid 2015 we had to make the hard decision to choose it or Ski MD as we couldn't do both to the standard we wanted.  An offer came in from someone who has made a commitment to grow JetskiJunk and take it to the next level which is good for the New Zealand jet ski community.

So we are back to 100% concentration of Ski MD and servicing our area, and if you are looking for parts - look online at http://www.jetskijunk.co.nz of course! If you are in the Christchurch area, you can also visit in person inside the Waverunner Centre on Ferry Road.
