    Default Berkeley E pump suction removal and reinstallation

    I was gutting this new project and was looking around where the pump intake is bonded to the hull. It has plenty of silicon smeared on the outside and inside where the aluminum meets the fiberglass. Does anyone have any instructions on re-installing it if the bond has been broken?

    Thanks.

    "Brute force" , all the time trying to not damage the hull or Gel, these insert jets were not intended to be removed as I'm sure you know , assuming its epoxied in you need to work very hard at "relieving" and scoreing as much of the epoxy bond (some carefull heat with a rosebud will help) When you reinstall you want to remove any and all traces of silicone and grind/clean all old epoxy from the suction and the hull to re-bed the suction housing in fresh epoxy putty, do yourself a favor and buy new stainless bolts and washers , clean and run a tap down all threaded holes maybe check into a gadjet (detail triangle sander/cutter tool below) to score the epoxy at the suction edges,one of the handiest little tools we've purchase in a long time call if you need pointers or help Tom

    It is a lot of work. I spent about 3 or 4 hrs chiseling(hammer and narrow wood chisel) the epoxy putty around the suction housing being careful not to chisel into the fiberglass. I assume bedding it in epoxy putty is best when reinstalling?? Is that what manufacturer uses? What kind of epoxy(brand) is best to use for this?

    Mine actually came out in about an hour. Seems the previous owner(s) decided to only silicon it back in. As for putting it back in, Marine-Tex is the stuff. Tom From JBP has kits with enough to reinstall the suction housing.

    Thank you. That is exactly what I needed to know. I bought a 26ft 1978 Hawaiian party cruiser and am doing some much needed repairs. My first jet and I have a lot to learn. Thanks for your help I posted pics on jet boat pic thread(#7789)

    I bet that would also work great on some transom and stringer work I need to do. Wish I would have thought to borrow one before I started taking out the intake
