    Default E pump hardware

    Do you recommend a shoe and ride plate on an e pump? The intake is about 5/8 of an inch above the keel. What gains should I see from this? The boat is a taylor sj with a 502. where should the shoe be located? 1/16 above keel? Any input would be appreciated.

    SJ Your Taylor could benefit from the Kits longer ride plate (stabilize ride,porpoise isssues) and shoe depth (or lack thereof) is definatley at issue for your particular boat. You are correct the shoe could be considerably lower, an 1/8 to 1/16 up is probably a could "start point" What loader (if at all) are you using now ? also some pump pressure readings would be helpful ,Happy to explain how and where to drill and tap for this Call if we can help Tom

    I recomend a rideplate on just about anything (same with a diverter), best $$$$ spent.
    Your pump sure sits a lot higher than mine, and I think an add-on shoe moght be a VERY good idea.
    DuaneHTP has told me he developed his Adapat-a-shoe add-on kit for the E/F pumps to stop a "hopping" tendancy to boats with them. It comes with a rideplate.
    I am putting a full-length rideplate on my new incarnation of my "F" pump this spring, at some point.
    If you ever need/want a new bowl, give me a hollar, I replaced my original C/E/F bowl this winter to move to a split-bowl, and the old one just sits in a corner.

    Running a curved loader, place diverter. Also will be trying a split bowl, droop etc.. What speeds can be acheved with the SJ E pump set up. This boat has been on a diet and has good stuff in it. Really interested in hole shot 800' performance speed is relavant. Any tricks?

    my 1978 taylor sj picked up 7mph from just the hitech shoe and ride plate kit alone, e pump with a berk a impellor. i was runnin a 11.5 to 1 bbf with a 200hp shot, it ran 84.3 in the 1000ft. taylors are extremely ass heavy so if you do the shoe/ride plate kit, be careful the 1st time out, let outta the go pedal slowly or you'll be on the bow ask me how i know
    don't even think about a inducer, alot of us tried them on sj's and noone in our club thought they helped, noone. the epump has such a small intake opening on a taylor sj, it doesn't take much to load the pump. keeping it loaded over 85mph is something i never could accomplish with the epump in the sj, so i sold mine, bought a tx19. i won 17 straight cove races in my ole sj it got to the point that local vhull jetters wouldn't race me anymore
