Does Any One Have A Stuffer Laying Around???? I Need Some Dimentions Off It So I Can Make One. I Need The Od, And How Thick It Is So I Can Find The Material For It. This Is The Only Thing I Can Thik Of That Would Make The Pump Not Push Water Upon Entering The Water. The Boat Floats On The Trailer, But Wont Pump Water Until I Stab The Throtle A Couple Of Times. After It Starts To Pump Water, It Is Fine For The Day. I Can Shut Off And Restart All Day Long And Be Fine. It Is Just The Initial Launch Of The Boat. It Must Trap Air In It And Cavitate Some How. The Pump Is A Berkeley 12jg, With A Don Bowers Auger And An A/b Impeller. No Loder Yet. But It Does Have A Droop. Im Worried About Killing The Wear Ring. Any Help Would Be Aprecitated.
You do need a stuffer but the reason why the pump wont pump water is its air locked. You need a bleed off on top your bowl to get rid of the air. I have a old style one if you want one, its 1/8" pipe tap instead of the new ones have a 1/4" pipe tap. Depends were you buy one they can be $25 to $45. I would make you one heck of a deal on the one I have if you are interested.
Shot gun is correct. Also when backing the boat into the water make sure your reverse bucket is not down, it helps a little. But you do need the deal SG is talking about any time you run a droop.
I have also seen it mentioned that putting the diverter in the up position when backing the boat into the water helps the air-locking situation as well... I know after putting my droop on, first couple of times I took the boat out it took me a minute or 2 before I could go anywhere, lol....
Why that helps I don't know, but probably 90% of the time if I do both those things I can take right off instead of sitting there in the way bumping the throttle not going anywhere. The air bleed valve deal will eliminate that problem altogether though.
You can use a piece of flat stock to make one, you can make a cone one to have the best but a flat one will work. Here is a picture of one that was for sale but is sold now. Not that hard to make if you take your bowl off for some dimensions.
They are all different in size, depends who you get it from. There a pain in the ass to get rite. Mine was finished when bought and after a test fit it was still to thick. I turned the lip on the bowl down using a brake drum lathe to get the space between the stuffer and the impeller down to specs. When all machining is done dont forget to use a good epoxy to fill in the hole behind the stuffer in the bowl.
