    Default First Jet boat got some questions

    Just bought my first jet boat, 79 Tahiti. Pretty solid boat from what i can tell. Took it out today to make sure everything works. And it does i see a few things i know could be better i.e. vacum advance not hooked up to carb(no vacum leak) and the bilge has sludge in it from a recent oil change. I dont know much about this engine. Its a BB olds, prob a 455, guys says "punch out to 500 roller rockers bla bla bla. Havent seen inside myselfs so duno. but how hard can i tach this thing? Didnt take it past 4500 today runs good and stronge i just blipped it to 5000 a couple seconds and it screems. realy comes to life. Is this a dangerious rpm? What things good or bad could be said about this set up... BB olds, high rise mani, dual quad webers? Thanks i am a nubie and look forward to some solid advice. Mike

    If it were an olds you wouldn't want to run it for long periods at 5000 rpm but I'm pretty sure that is a BBC.

    Olds will live longer not going above 5k on the tach. Also keep your good eye on the oil pressure gauge the one I had use to do tricks, like drop to near nothing after a short burst to 5k.

    Looks like a good boat for a first jet though. As for solid adviceI'd say take it easy on the Olds and put a big block chevy togather and do a swap durring the off season then you can give it hell.


    WARNING there are ford nerds around here that will try to lead you in another direction, just ignore them. Remember its only as safe as the driver. Have fun

    Damn, that is a BBC, nail it. but watch the oil pressure any way

    Welcome to the boards , Congratulations on your Aquisition, The Folks are right I belive looks like BBC and Your Jet is a Panther BTW , A Moderate HP BBC will spin the Panther 5K + which should be easy for a BBC Good Luck Tom

    Douche out the bilge with detergent and get an oil drainer kit , you'll be happier also leave the Vac advance disconnected

    That figures it could be a BBC i dont know for sure. I bought the boat from a friend in town who was selling it for the owner who left state. I wish i knew for sure. I tried to find the engine codes on the front left side of block and there are none to be found. Whats "good oil preasure" ? 40-60 sometimes lower. and if it truely is a BBC wh I ats a good RPM to speed around at, and whats the max? If i take some closer pics of the block would you guys know what size it is? And thanks wildhair, I want to nail it a little next time. Is the panther jet good or no?

    look at the right rear near the bell housing flywheel area I believe. Your block codes should be there.

    Edit: driver side rear should have your block code

    Nice Boat, BUT NOT A OLDS! BBC for sure,, as far as the pump go's they are not a good pump if you want horsepower! and there is not much you can do to them to help change the ride of your boat. As to where you can with a berkely or a dom,,,

    Like others have said, without doubt, that is a Big Block Chevy. Big block Olds looks completely different. Now what Cu In BBC, the only way to know for sure is to tear it down and check it. The casting number will tell you what it was when it left GM but it will not tell you what has been done since then.

    I've been in Nuevo for the last 6 years and Menifee / Canyon Lake the previous 15 years.

    Quite the culture change to OR huh?

    Give us your casting #'s. You can at least be sure what your block was when it left the factory... like previous post you really don't know what you have until it comes time to tear into it.

    We can all agree though that you absolutely have a BBC which is a good thing. Less likely you'll have the proverbial oiling issues associated with the olds.

    Congrats on the new boat and welcome to the boards

    cool riverrat, im glad its a BBC. I will get casting #s tomarrow i keep it in a storage with a dehumidifier and radiator heater. I live on the coast so the air is salty and moist. Big culture shock, people here are friendly and honest for the most part, lot of tree huggers, hippies and rednecks! I love it. My ladys family lives in Menifee off Newport. I know the area well as i worked construction for years out there too. Thanks again for the help. ttyl

    LOL Small world... My parents live off of Newport as well.

    I have a friend who moved to OR and he described it close to the same way. He says he doesnt even need a television because he's constantly outdoors and doesnt have time to watch.
