The options for the SeaDoo supercharger rebuild service only list 2 options, 185 or 215/255/260. Will one of these 2 options work or is the Chaparral something different. Thanks

    hi. First time poster here. I would like to remove my supercharger from my 2015 glastron GTS 207 rotax Sc and send to you for a rebuild. Iím ok handywise but not great. Iíve changed the oil
    and removed jet pump once. Iíve searched YouTube but no luck, do you have a link with pictures or anything showing how to remove this supercharger from my boat? My engine hatch barely opens and the engine bay is deep I canít even really reach down in there. Am i am supposed to unscrew and remove the engine bay hinges on outside of boat to open the engine hatch way more ?

    you are going to need decent access to the engine in order to remove the charger. Removing the hatch is likely going to be needed. Post some pics so some actual advice can be given on how to proceed. The bolts are difficult to get out as it is on some pwc's as you cannot see them without a mirror or camera. After doing this for years I can now get them out by feel

    a deep engine install is going to make this pretty painful

    mark the of the hinge outlines with painters tape before you start.

    Don't ask me where that advice comes from

    Jerry, do you do upgrades when rebuilding the 300 superchargers, if requested? if so, what is typical and what would we need with engine mods to keep up and keep the machine running well? I figure when my time comes I should have a plan in place.

    The 300 superchargers are not considered rebuildable, Sea Doo deems them "maintenance free" and therefore offers no repair/rebuild parts for them.

    You can install this upgrade https://www.4-tecperformance.com/ind...oducts_id=4621

    To run the supercharger upgrade you will need to use these fuel injectors
    https://www.4-tecperformance.com/ind...oducts_id=2156

    and the MaptunerX tuning for that supercharger upgrade and those injectors

    Yes, you would use this upgrade
    https://www.4-tecperformance.com/ind...oducts_id=1923

    and these fuel injectors

    It's absolutely worth it. It makes a big difference over the stock 185 supercharger

    I looked at upgrade kit it says it’s for a 215 , will it work on the 185. I have twin 185,s in my speedster 200 would it give me some more top end
