Locate the HIN plate on the aft deck of the PWC (jetski), the last two digits are the year of manufacture.
In this example of a Seadoo HIN the year of build is 2020

Figure out where you're going to be storing and lifting your Seadoo.
NO HEIGHT RESTRICTIONS:
If it is lifted & stored on the foredeck, flybridge, aft deck or similar where there are no over head height restrictions then the Standard height kit is the one to choose.
LIFTING HEIGHT RESTRICTIONS:
If the Seadoo is lifted / stored in a garage or similar then you'll need to opt for the restricted height lifting kit. This is only applicable to some 'newer' (2018+) models where there is a new hull design which has a wider beam than previously such as the GTX Limited, RXT-X, FishPro etc. Where relevant, this will be shown as an option on the relevant product page.
