    Default Old School Jet on New School Race Boat 2016

    April 14, 2016

    Hello People

    I had to return to old school technology. New school tech / equipment just didn’t perform as I thought they would. My American Turbine bowl and 3A Stainless impeller were installed in 2015 and cracked, broke / welded before April 14, 2016.

    I want to give thanks to Jim Brock - Cyclone Speed & Marine for the quick turn around of the replacement parts.
    Also notice the bowl is polished all the way through. "Old school part with new school technology"

    The 149 Tsunami BGJ has old school technology reinstalled to help control the part failure.

    Hello People

    The spacer is just there to try and equal the length of the ATJ Bowl that was replaced.

    Trying to keep the “E” ticket ride as similar as possible to the way it rode with the American Turbine stuff. The spacer made the total length long by a ¼ inch.

    All the other setting are the same as they were at the last race, ride plate angle, nozzle angle, tune up.
    Naturally the impeller was changed too, the 3A Stainless was cracked and welded. Don't think its a good idea to use in this boat.

    The 3A Stainless blade at the bottom is the one that was repaired by MPD, and the race prep work. The size is standard.
    Jack said the run out will be a little distorted, but nothing to write home about. The impeller is for sale.

    This impeller will work fine for boats with less than 1400hp, probably will have to have it cut down to something smaller.

    I figured the spacer might be a trick to make the hull think the pump was setback farther than it is and change the thrust leverage angle . Same as running a setback plate on an outboard to take advantage of the extra leverage it provides

    Hello People

    No trick,

    but there have been boats with the jet nozzle set way back, Marty Stretch Limo had a deal where the nozzle was way out there.
    I think that 21 foot boat ran the “8’s” at Ming.

    We had some uncontrollable events that couldn’t be fixed at the track. Spike Gorr, Gorr Fuel systems, had the parts I purchased to solved the fuel issue, but the others were not solvable at the track.
    I have found the issues and they are being addressed, so with that being said, the 149 Tsunami with the “Old School Jet” will be ready for the May race.

    Ralph and Spike Gorr, thank you for your help
