    Default no hose connect on 95' ultra jet boat??

    well im the proud new owner of a 1995 19' ultra custom jet boat with a 454/dominator jet. The only problem is i cant run it in the driveway! I also have a 1967 tahiti with a 327/berkley and it has a hose connect to run water through the engine and the greese fittings on the bowl to lubricate the jet. the ultra has neither of these....is this common? i know the boat should be ran and not just sit for months, the tahiti gets ran once a month at least. so i need to install a hose connection on the water line going to the block and i i need to have another hose going into the nozzle of the jet to lubricate the wear ring? this is a whole lot easier on the tahiti...

    Most will tell you not to even run it on the hose period, If it's not a freshly built pump IMO a short 5 or ten second run with water isn't going to hurt much unless you picked up some crap towing the boat back to the house. I've unscrewed the fitting out of the jet(water outlet to motor) and went to lowes and bought a brass fitting that I can clamp a hose on. Also I've pulled the inspection cover and had my 14 year old hold the spray water down the inspection cover. Obviously neither will get any water to the motor. Part of the reason I'm responding to this is I'd like to hear everyone's opinion, on which of the above is the best, or if someone has a better way.

    The people who run their jets out of the water likely never see any damages or lack of performance, and likely never felt the difference of a tight pump vs a worn out pump.

    the tahiti has a T valve that when connected to a hose sends water to the motor and the pump, you can adjust the valve thats should already on the the water line to determine how much water goes to the motor or the pump. I was just told on another forum that this is the way to go. maybe some people live 5 minutes from a lake and can drop it in the water everytime they want to run it but im a good hour from the closest lake and gas is expensive...

    there are several "Great" pump builders out there & each one will tell u NOT to run the jet hooked up to the motor! especially if its been blueprinted/clearanced etc...this will wear out the wear ring etc quickly..."disconnect" the jet (even if its a PITA) from the motor & u can run water thru the motor all day!...i have a Y hose that hooks to the front of the heads & i hook the garden hose to that...circulates water thruout the system...works fine...just my .02 cents

    This is a bunch of BS!!!!!!!! The impeller should never touch the wear ring (if it is installed properly) and the tail shaft bushings and the main bearing are lubricated, so there shouldn't be any ill affects from running it on the trailer. This is even what Berkeley says and I think that I will believe the people who manufacture the pump. I only run water to the engine, right now, but when I redo the plumbing I'm going to hook it up so that I can run it to the pump as well, with only one hose. And another thing, many of use CANNOT disconnect the drive line while the engine is in the boat, trust me I've tried (just ask snoc653 here on the boards, he knows it is impossible on my boat). Here's a link you should read.

    I am all for you getting your boat running, but as they say....

    Stand down soldier....

    My 79' Challenger has a Dominator pump. The tail bearing has no lube. Its water lubed.....

    Well, I wasn't talking about a Dominator, now was I??? I clearly said Berkeley and so did the OP!!!!! And by all means come on over here and disconnect my drive line without pulling the entire engine!!! BTW it's impossible.


    nos1967, when you say that the bowl doesn't have the grease fittings on the bowl, does it have brass plugs instead, for oil to be added, or is it completely smooth?

    Running a Jet Boat Out of the Water


    2 issues here:

    #1

    Ideally the impeller should not touch the wear ring. However if you examine the loose fit on a berk(I assume others too) there is quite a bit of slop in the bowl register on the suction housing. That means the bowl can move around quite a bit before it is tightened down. If you install the bowl with the suction housing in the boat it is really tough to get it set up correctly. If the driveline is connected and you install the bowl simply relying on the register to locate it, on a fresh pump, the wear ring & impeller will be touching. Run it on the trailer a couple times and it will fix that problem for you

    #2
    When trailering a jet boat, lots of road debris ends up in the pump, right between the weat ring & impeller. If your pump was set up properly, you could probably rinse real well and be okay, but if you can remove the driveline by all means do so. Running it withough rinsing is asking for bad news, maybe not right away, but eventually.

    Yes, I agree completely with #2. After towing mine home from the warehouse, I turned the hose on full blast and stuck it in the nozzle and let it wash it out for a good 20 minutes, just to be sure. But, soon after putting water through the pump, a couple of very small rocks came out of the intake, so I am very glad that I did wash it out.

    And yes, if you can remove the drive line, by all means do it!!!!! If I could, I would. But to say "NO, never do it in any case", is absolutely ridiculous. Because I know that in all 3 point mounts, it is impossible. And on the older drive lines (like mine), it cannot be done, even on a 4 point (like mine) or a rail system.

    I agree.

    Get a tee with a hose fitting and a cap to split water to engine and pump...

    My drive line has a seperation point right at the spline yoke. I also set my motor so that there's 1/4" end play between the bearing snap ring and the back edge of the yoke. This allows me enough room to slide the shaft back away from the motor and remove the shaft should I have to, but it also makes it so that in the event of a thrust bearing failure the pump shaft won't slam the crank when it slides forward.

    That sounds like a cool set up jetaholic, I may pm you for more info. Guys don't get me wrong here I'm not trying to be the poster child for go run you pump out of the water. But lets say a fella was to duct tape his intake every time before a tow(or something simular) and wanted to start it for a few seconds. what's best t the line, or spray down the inspection cover?? or?
