Hi I have a 2009 vx deluxe and I havent ridden it in a month and am ready to winterize soon for the Minnesota winter. I have read that you need to run the ski on the hose 3-4 times. What is the point of this if I have only ridden on lakes, and the ski is completely dry. And any other useful winterization tips and is it safe to leave battery on battery tender indoors.

Thank You

Never heard of having to run it on the hose 3 or 4 times?? I would recommend running some fuel stabilizer through the system along with some injector cleaner. I fill the tank put in Stabil-Marine fuel stabilizer and Yamaha Ring Free Plus injector cleaner in the last tank, then run some through the engine. Other guys like Seafoam instead of the Yamaha Ring Free Plus.

After you run this mix through the engine and it is still hot is a good time to change the oil. Most mechanics recommend doing the oil change as part of the winterization..........that way you remove many of the contaminates that can damage the engine if they sit for long periods.

After the oil change disconnect the water hose and run the engine dry for 15 seconds, blipping the throttle to force water out of the exhaust system (it helps if the bow is up and the stern is down). Wait until the engine completely cools (several hours or the next day) then do another dry run for 15 seconds blipping the throttle to force more water out (it usually take 3 or 4 times to clear most of the water). Now there is no need for antifreeze.

Last step is to remove the hose going from the air box to the engine at the engine side and spray in fogging oil for 5-7 seconds. Then start the engine and let it idle for 15 seconds and shut it off.

Now you can pull the battery and put it on a tender (be sure to add distilled water to the cells if you have the flooded type of battery that came with the ski). Check the battery over the winter because you may find that more water needs to be added. If its an AGM type you don't have to worry about this step. No problem keeping it inside, but be sure you have the proper type of battery tender. Some of the cheap ones will ruin an AGM type of battery.

In last step which hose are you talking about? Can you spray each cylinder for 5-7 seconds instead? Thanks for your reply

Take a look at the owners manual it has a drawing of the hose to remove. Page 69 in the 2007 manual. Its much easier to spray into the intake opening rather than have to remove all the plugs and ignition coils. Plus you do not risk bending a valve if you spray in too much oil. There is only one hose clamp to loosen to do it through the intake opening.

Find the owners manual here if you don't have one: My Yamaha Prompt - Owners Manual

I always put my batteries on a tender and still seem to have batteries go bad halfway threw the next season. Makes me think maybe its just best to buy new batteries every year. I really hate to spend the money when they batteries seem fine, but having battery issues on the water sucks allot.
