I just purchased an Ultra 21lx with a jet I'm not familiar with, sorry for the newbie questions. My previous jet had a cleanout in the bilge and a couple of plugs that I put gear oil into, this one is completely different and I'm not familiar with it. Need some advice for how to clean it out (if debris gets in it) and what (if any) maintenance is needed. I think it's a water lubricated pump maybe (don't really know). If it is, can you run these dry for any length of time (30 sec even or??)?? Is the clean out the triangular plate with the three bolts? (seems a lot more difficult than the two wingnuts that I used to have on the other jet). I've attached a picture, I'd love any suggestions, recommendations, help, etc...............
thanks
