I had my spark winterized and now the dealer tells me I have to come back for a service to replace the spark plug and take tape off the exhaust, both of which he says requires removing of the body of the Jetske. Any input?

If you go by what the shop manual says yes, lots of people are going to have many different opinions on what to do, what Brp will recommend to do is what they feel you need to do to make sure you have trouble free operation for many years. there are things that some people may not do for their own reasons like replace spark plugs, charge and load test batteries, check wheel bearings etc... but everyones situation is different, for some owners if they fouled a plug at the lake not a big deal...just pull the top off and replace it, others it means hauling the ski back to the dealer and paying them to do it and loosing a weekend on the water because you didn't want to spend the money to replace the plugs in the first place, plugs aren't as much a problem if the engine isn't fogged (an engine that sits for a long time that hasn't been fogged will be prone to other problems) but once you start the machine that has been fogged you could partially foul a plug and I have seen where it runs on the flush on land but put it in the water under load and thats when it acts up, so it really depends on what you are able to do yourself or how upset you will be to miss a weekend out on the water because it won't run.

I am about to winterize my Sparks, and I want to replace the plugs as well as this is the end of year 2.

The parts guy told me not to put the new plugs in after I fog the engine, because next year when I start it up, it will foul the new plugs.

I am going to follow his advice, which means removing the top when I service them, and then removing the tops again next spring when I get them out of storage to replace the plugs (after I run them for a few minutes to remove the fogging oil).

I guess my question is what is the difference between new and old plugs with regards to fogging the engine? If you didn't plan on replacing the plugs, wouldn't you foul your plugs when you start it up in the spring, regardless of whether they're new or old plugs? Therefore, any time you fog the engine for winter, you better have new plugs on hand for the spring?

I hope I'm making sense, it just seems like fogging the engine leads to bad plugs, which leads to replacing plugs every year.

I always replace plugs in the spring once I start it and run it on flush for a while to burn out the fogging oil, when you fog the cylinders then start the engine on those plugs the fogging oil can half-foul the plugs, many people have never had a problem not changing the plugs but I have seen it enough times where it runs fine on land and then put it in the water under load and it is only running on two cylinders with one plug fouled. Since it isn't a 5 min job to change plugs on the spark I change them before I head to the water, the risk of a fouled plug on the launch isn't worth the price of plugs and the time to take the top off.

what you can do if you are cheep is fog in the fall and start up in the spring on the same plugs, just put your good plugs in once you have burnt the fogging oil out.
