    Ultra 250/260/300 Update for Ultra 310 Exhaust Filter Retaining pin by Nicjak

    Quote from Nicjak HERE

    Well my ski has clocked 60hrs but the last few hrs it has had a hesitant start whilst on the water, yep a sure sign filter is gone. Who ever says running without the filter does not effect starting on the water is full of sh it, it does I dont care what your excuse is.. as my filter was completely gone and I had no rpm loss I needed to be sure it was gone, well guess what as pictured I had to cut the waterbox in half to remove it. Only a few weeks back a guy I helped had exactly the same problem. Wonder how many of these are going to show up to the unwary.


    Well talk about easy fix took all of about 15min. Remove seats and base, remove and lower bypass valve and catchcan. Place rag in to catch shards. Drill upto 11.5mm, tap thread too 1/4" BSPT 19tpi. Insert pin and tighten




    All done no more jammed filter worries.

    Nic This is to keep the Exhaust filter dropping into the water box?

    Thanks Rod

    Where did you get the stop pin? is it the OEM part for the 300 or did you find it elsewhere?
