    Default pump rebuild ??

    im getting pretty close to rebuilding my pump (berk 12jc) can it be rebuilt in the boat still or is it just way easier to pull the whole thing out and do it. And are there gonna be any specialty tools i need. how hard is it to rebuild (im very mechanically inclined)Any advice you guys can give me will help ive never done one before thanks in advance Pig

    You could "build it" in the hull with the engine removed I suppose (shaft comes out the frt) but as simple as it is to pull this jet , It make much better sense to simply remove it and get it on the bench to rebuild or repair , you'll have a cleaner betterand less ackward job , The biggest obstacle you may encounter is removing the Impeller nut and the impeller (depending on when it was apart last) although the "special tools" are nice you will likley be able to get by with a clandestine 2 or 3 jaw puller and other standard shop tools, lots of good info and support here from the folks Good Luck Tom

    You will either have to unbolt the suction piece from the intake and remove the pump or pull the engine since the drive shaft has to come out of the pump forward. I've done it both ways. It was easier to pull the engine than pull my transom plates the second time around. Mechanically they are quite simple and rebuilding one is not overly complex. I have done it twice. But as with most " simple" things the devil is in the details. The quality of my rebuild compared to many of the guys on here who actually know what they're talking about does not compare. There are probably numerous steps to be taken that will increase longevity and efficiency that I cannot give you informed advice on. Tom from Jetboat Performance seems to always have the time for my dumb questions. He's a great resource here on the forum. There are others who are always willing to give good info. Good luck.

    Edit: as I was posting this Tom from JBP responded as well. Listen to him not me.
