Suspect this is a mis-stamp or re-stamp assuming it is an "insert" type jet the odds are its a 12j "E" or "F", "Fs" had OE trim "E" had standard steering  Email me a picture if you can and I'll post it for you Tom

Supose it could be a JJ pump, maybe a variation of another model Berkeley offered, we had a JH pump that was installed in an old '68 Schiada we aquired.  The JH was identical to a JA exept it came factory(best i could tell) double drilled on both sides of the bowl had a stainless impeller and also had a jetovator installed.

Hey Dad, don't forget the original JI pumpthat was in the Syndicate, not the current JI that skip mentioned.  I suspect it was a very short production run.  An adaptation of the jet o vator nozzle used on F Pumps.



Most of the pieces are the same as an F trim but the reverse bucket is totally different and the gimbal has a tiller arm added on the upper left had corner.

I am by no means a Berk expert, but that pump sure looks like an E pump to me 

I know that my old Taylor was a 1984 and it didnt have a rectangle tag it was a oval shape. So Im going to asume that it is a E pump.

Ive got a 12JJ pump too.   Its on my 93 Commander.  No droop snoot available.  The only advantage is that the bowl can be removed from outside the boat and dont have to pull the engine.

post a picture of that bad boy. I've got an 89 commander
