I haven't had a jet ski in the last 15 years so this is all new to me again. My local dealer tells you what they want to tell you so you buy what they want you to so I want to get a little educated before shopping. I'm looking for something on the cheaper end so that's why I am going with a spark, I plan on buying a 2nd one eventually plus already have a boat. I'm assuming the ho is the 90hp engine? And is it possible to buy a 90 hp without the ibr package since it's not a necessity for me. Thanks in advance.
