R&D Sea Doo Sponsons RXP-X 300/ RXP 260 closeout

The R&D RXP-X Sponson Kit will increase top speed stability in rough water conditions, as well as add increased and improved turning performance. The Sea-Doo RXP-X 300 sponson has a unique stock feature that is tabbed as a “decelerator fin”. The decelerator fin does a good job of keeping the RXP-X stable at cruising speeds with a stock engine package. However, who needs a decelerator fin when you want to accelerate? The Pros have incorporated into the this Sponson a lot of race inspired technology to keep the RXP-X 300 ultra stable at top speed, corner sharp and smooth, and actually increase acceleration from zero to 30 mph by leaving the “decelerator fin” out of the design. We have done all this without loosing any of the cool inside lean handling performance the RXP-X 300 is admired for. The Pro Sponson Kit offers 2-position sponson blade adjustability, which will guarantee this kit to out perform any other 1, 2, or 3 up. The Pro Sponson Kit offers a smoother more predictable ride with much better low and high speed turning capabilities. Track tested and race proven! Kit comes complete with all hardware and instructions and easy install



From One of The Best

Jetski tuning company in the World!!!

Please do not buy or make an offer on this item until you are certain it will fit your particular Jetski!

Please read the following information before making an offer or buying this item.

A lot of time is spent cleaning, checking and listing these parts, so please take your time to study any photo’s or descriptions carefully before purchase.

Please contact me before raising an “Ebay case” or leaving negative feedback as I will try my best to resolve any problems.

On most occasions you will receive the item as shown in the photo, however on a very rare occasion, you may be sent an identical item, but not the actual one shown in the photo.

This may fit other similar models so either check with your dealer or research it yourself before buying. If you have any questions please ask before buying or bidding. If you do not see your item listed it does not mean we do not have it; so just ask or give us a call at tel 36 70 9044678 and it can be listed on Ebay for you.

You MUST make sure it is suitable for your ski before buying it or making a best offer.


Due to courier restrictions, some larger or heavier items may incur an additional postage charge so please check if you want delivery to one of these areas.

You must ask first for a postage price if you want delivery to a non EU country.

I will try to post your item as quickly as possible (usually the next working day) after payment is received. On some occasions I will not be able to post this quickly so you should check the standard postage times shown on the listing. No Guarantee is given for any delays after the item has been posted and proof of posting is always obtained.

Collection may be possible for some larger items but you must contact me first before purchasing the item.


Unless you are competent in Jetski electronics and have properly identified the fault, I would suggest you seek advice from an expert first and not just guess what may be wrong! You may cause major damage to an electrical component (MPEM’s and ECU’s etc) if you have failed to correctly diagnose what caused yours to break!

I will not issue a refund for returned MPEM’s that have been A.Y.B. as “tested and fully working” unless it has been fitted by a certified Jetski engineer or approved repair centre. (Proof must be supplied)

Please be aware that some electrical parts cannot be fully tested before being posted (usually specified in description). For this reason, please test the item on your jetski before it is fully fitted. No responsibility or labour cost is accepted for items fitted that are subsequently found to be faulty or broken.

During the removal of certain parts, some electrical items may be supplied with the terminal pins removed from the plugs. You will need to check that they are placed into the correct terminal holes on the plug before re-fitting. Special terminal pin/plug removal tools must be used to remove the wires from the plug for fitment. You must use this tool, as anything else is likely to cause damage to the pins and cutting and re A.Y.B. ering is an absolute NO NO!!. Some wires may have been replaced back into the plug to prevent damage during transit so please check that they are in the correct hole before fitting
