Sorry! My name is Steve, and I bought a 77 Hawaiian day cruiser. Picks will come soon. Went out last Sunday and wasn't happy with noises from my BBF. New to jet boats, but not BBFs. Will sort out that problem and start enjoying the boat. It's the old enjoy while I restore kind of project. Newbs like my self appreciate the posts we recieve on sites like this! Thanks everyone!
On most of the Berkley pumps there is a tag on them inside the boat where it connects to the motor.
It will have a pump model number like 12JE 12JG etc. The next letter will have A,B. etc.
That is what the boat had originally 12JE A came with an A impeller.
The only problem is that it could have been changed.
