    RE: Gas Jet Boaters


    ORIGINAL: kamipalms

    Hey Mick,
    Yes it is a plug and I built the hull to accomidate the the Hobby king or MHZ pump
    I know pump choices are limited and depending on weather the Hobby King pump is going to be any good or not , there are not too many other options to choose from.

    I noticed that there are a few people having CG problems with the 36" hulls so I set the transom back another 1/2 inch.
    In the pic the black line was the origonal transom and the extention sits at an angle so it doesn't form part of the keel.
    Yep you are going to have your hands full with a 36" hull, i have one and i can tell you they are very touchy , but hey best of luck with the build though. and make sure you post the build thread.
    Mick

    RE: Gas Jet Boaters

    Hey guys..... here's the link to my Davette with KMB jet and NEU1518y BL....... I know not gas, Dana has his powered with gas, think he is still running the KMB jet..... it is a little on the small side. (maybe ok for stock motors). Even my 1518y is a little to much for the KMB. If the HobbyKing jet is any good I hope to put one in DaVette drag hull w/ modded zen........

    I plan to put on a RC sprint boat race this summer...... will post more when I have it all together....???

    here's the link, Jerry Dunlap was driving...........

    RE: Gas Jet Boaters

    Well I finally got around to start the build onthe Davette jetsprint hull with the MHZ unit.

    Here's a few pics. I've started the build thread on Modelgasboat.com

    RE: Gas Jet Boaters

    I long for someone to take up production of the Swashdrive units again.

    HobbyKing had the new CNC JetPump - "PRODUCT ID: JETPUMP"
    Specs:
    Drive Shaft: 8mm
    Impeller Size: 53mm
    Impeller Blades: 4
    Output size looks to be about 30mm.
    No reversing bucket.
    No information on thrust.
    $369.99

    Reviews are generally positive on finish and first impressions but it sounds like the components might not last too long.

    Of course, the product is backordered.
    Plus, the vendor isn't very helpful with information about the unit. They actually said they weren't qualified to recommened anything about motors to go with the unit, and they cannot/will not tell me if there are spare parts available. They recommended that I search through their website for parts.
    So, it looks like we would need to buy two units and disassemble one for spare parts and also engineer the coupler and a reversing bucket.
    If production only lasts a couple of years then this turns out to be a very expensive set of holes in the hull of my boat.

    Anyone have updates for other Jet Pump units?

    RE: Gas Jet Boaters

    In the photos I see a brass fitting mounted at the top of the "bowl" just before the water exits the nozzle.
    Two questions:
    1. is that intended to be a place to hook in a feed line for cooling to the engine like a radiator hose would be used on a car?
    2. I wonder if you could record PSI from that fitting and then use that number to get a good calculation for thrust?

    (I would have inserted a photo but I'm getting the "500 Internal server error" message....)

    Yes the fitting off the Bowl will be the cooling water supply.
    Pressure could be equated to thrust ... but what ever it is would have to be found out within a test cell with measuring equipment.

    I miss my swashdrive davette now, figured by this summer some decent pumps would be available [>:] ... this sucks !!

    RE: Gas Jet Boaters

    I've also been working on another hull for a friend. All it needs is the roll cage to be added and it's done. Dana's hull with an MHZ unit. I don't like the MHZ unit, but it's all that was available then. pics are taken on a phone, so excuse the quality.

    RE: Gas Jet Boaters

    thanx for the vids, looks like the hk pump works well. i have some pix of a home built pump, i built this thing about 12 years ago, thought i would wipe the cobwebs off it and refab some new parts for it see if i can make it work better than before,the whole pump housing was made from a peice of nylon and the nozzel,change some of it to allu.last couple of pix are my jet boat from 12 years ago,it only went about 20 mph,so hopefully with the new parts i made it will work better, just have to build a new hull now,won,t be able to test till spring , the pond i go to is starting to freez over.

    so hopefully with the new parts i made it will work better
    if you are going to redo the stator, give it more angle to the leading edge and have more curve to the blades instead of mainly straight.

    that will made it more efficient and go faster.

    I'm going to post a few build photo's of a DaVette Sprint boat with a HobbyKing jet pump I'm putting together for a customer. It will have an RCMK engine with a wet dual exhaust . I decided to install everything first before I install the deck .

    No it's not carbon , it's just black tooling gel and glass. I'll be painting it on the outside .
