New boat!
« on: June 17, 2021, 02:38:14 pm »
Hey all, always wanted a jetboat and finally found what I think is a smokin deal so I pulled the trigger... a 74 Taylor SJ.  Boat seems to be pretty solid, was set up with a olds 455 which the previous owner pulled for a rat rod project.  Going to start stripping it all apart and had a couple questions I was hoping to get some insight on.  On the stringers it looks like someone might have dropped the engine or something fell on them because on the spot on both stringers theres cracks and one has a chip down to the wood.  Tap test shows that its still pretty solid I was just wondering if it could be repaired or should I replace the stringer.  Also I was wondering if anyone has more info on the diverter on the JE pump.  Only markings I can find on it is "CSM".  Any help is greatly appreciated and am excited to be part of this group!

That CSM diverter should have a hell of a roost. Does it have full stringers or ΒΌ stringers? If the are full stringers, repair it accordingly. The JE pump doesn't have the best intake, so the performance gains will be minimal, unless a JC intake or the like is installed.(a huge undertaking) A great candidate for LS swap, or go with an SBC, parts are cheap and plentiful. BBC would be my next choice, depending on your budget.

Thanks man, appreciate the info!  I literally cannot find anything about CSM except it was a company out of San Jose CA that went tits up.  The boat is a 1/4 stringer I guess since they stop right behind the two bucket seats.  Honestly I have a family of 5 and the 3 little ones are 3 5 and 7 years old not looking to go pure performance mainly to bring the noise and make some memories with the family.  A coworker of mine has a Tahiti and is giving me his old 460 BBF so ill be using that.  Priorities are safety, reliability, and fun factor.  Should I just go through the pump repair the stringer install the motor and have some fun?  Keep the diverter or ditch it/relpace with a place? Again thanks for the insight cant wait to get her on the water.

I think on the JE pumps, to replace the bearing, the shaft has to come out the front. I'd definitely pull the bowl and check out the back side of the impeller, and condition of the bowl.

I at least try the CSM unit, however, it trims first, and steers second. Similar to a Berk Jet-o-vater. (Provides wonky steering) A Place diverter steers first and trims second.

A mild 460 should push it to the mid 50s. I'd keep an A impeller in it, which it probably has, given it was 455 powered previously. Definitely need to check it out. Logs and snails for having the kiddos around.

Hmmm, half stringers? Up to the back of the front seats? Need pics.

Oh, and welcome to scjb.

Awesome info thanks again, got a pic of the stringers, tore out some of the ratty carpet for a better pic and found something that probably needs to be replaced instead of repaired  :'(   Its hard to tell, but do you know if the CSM unit was just an electric motor, or was it a hydraulic motor/pump ?
