    Default Add 2nd water cooler line to motor

    I'm a newbie so be kind.

    I want to add a 2nd water line to my motor, pick, etc. The motor is running about 135 which I know isn't hot but I would still like to add one.

    Any suggestions? Parts, etc. that I would need.

    I'm running stock parts now.

    Thanks in advance,

    Rick

    SV or UL-1 rudder blade is a direct replacement with watercooling, keep the sponson pickup. I ran my second intake line though the "exit" on the back of the boat and ran the exits through the side of the boat where I can see the water exiting when I drive by.
    Made my own exits using large pop rivets with brass tubing epoxied in, they are long enough to go through the hull and inner tub, just had to drill straight through and epoxy the outlets in place. Look just like store bough ones from the outside.
    If my boats upside down then who owns the one I thought I was driving the last two laps?

    Rick,

    I too found that the UL-1 / SV27 rudder with a built-in pickup was a direct bolt-on replacement BUT the pickup was rather high up in the blade. I lowered the pickup (a fairly tricky job) but ended up bolting on a spare Speedmaster rudder with an enlarged orifice I had laying around.

    With some scraps laying around, I made a simple propwash pickup which works great

    Keep in mind that watercooling, while nice to have, won't cure an overstressed setup. Stay in the "safe zone" and enjoy the MC ; it's a great boat

    Interesting. Picked up the UL-1 rudder blade. How do you get the blasted pin out of the stock blade pivot to replace it with the UL-1blade?? All set screws out and cannot get pin out.
