So I have a bit of an issue with my 2020 Spark Trixx. The dealership I bought my ski from doesn’t appear to have given me the right info, as they mixed up the flush port and drain port and told me one was the other. Trying to use that information to my advantage, I attempted to winterize the ski myself and flush the exhaust out with antifreeze. Well, now that I realize that I was using the wrong port, I learned that the reason my method wasn’t working was because I was trying to dump coolant straight into the hull lol. So because of that, my exhaust got no love for the winter, and I believe it may be causing my ski not to rev out like it should. My spark is running 2k RPM less and 15 MPH slower than when I put it away, should I be concerned about buying a new exhaust and taking it for service, slapping new spark plugs in it, or just riding it out until the old neutralized fuel cycles through and getting fresh gas in it? I’m sorry if this question is all over the place as well, and if anybody has any incite I would appreciate it a ton. Thanks yall :)

Hi there y’all, this is my first ever post on Reddit so bear with me if my formatting or anything is off lol. I’m brand new to the world of 2 stroke jet skis, and have been wanting to get an old stand-up for a while now to learn how to ride and wrench on. I have very limited knowledge of how these machines work, but I do have an understanding of how simple things like carburetors and exhausts work. Is there any type of place or platform where I can gain some knowledge and experience on how these things work, as well as what a good first stand up ski would be? I’ve been seeing that a JS550 is a great place to start with the ease of access and maintenance, however with me being a bigger guy I just don’t know. Thank you for the time, and have a good day everyone :)
