Sea Doo IBR nut for retrofitting new style IBR

myminifactory

  This is what you need for retrofitting a new style IBR in a older Spark hull . The newer IBR has a bigger diameter wich i drilled my hole for, but the IBR nut for the new style IBR has the threads so far in the nut that it wont thread on. Root cause for this is that the 2015 hull has the IBR hull through the jet plate and the hole is thicker. Overall threads are same length on both IBR.   This nut will reuse the original gasket, and have threads all the way out so it will reach the threads.TIP: Heat the threads carefulli with a match, before you test screw this onto your IBR unit. This will make the threads to go easier.
