    Looking for opinions on using mech. tabs on a GPR

    I interested to hear some opinions on the pros & cons of mechanical tabs on a GPR. I'm considering using them along with an auto drop nozzle on an upcoming project. I believe the ones I'm looking at were made by bullet racing & attach to the fixed tabs. I'd expect some speed loss, even in the up position, but how much?

    Well I haven't found anywhere you can buy them NEW so I imagine if little sh*t breaks, finding parts could end up being fruitless

    I Have a Set On My GPR

    The pros
    - Holeshot. With the tabs down, you just go WFO and the ski planes out instantly. No cavitation, no unloading of the pump.
    - Stability. When running at high speed and the porpoising starts, you can just pull the lever and release, and the ski is instantly stable.

    The cons
    - Uhhhh... installation? I modified my transom so I can have the manual trim and the mechanical trim tabs
    - Springs. I still have not found stainless return springs, so my springs are pretty rusty.

    I got my SST springs for my mech tabs at McMaster Carr.
