    Best water pick-up ever!

    I bought one of these from ose for my sv-27/stiletto outboard conversion and I have to say this is the highest flowing water pick-up I've ever used! It almost looks comical how much water shoots out the side of the hull even at low speeds. I know its not the most hydro-dynamic piece, but there is no doubt that my esc is getting all the cool water it can handle. I will definitely be using more of these!!

    Where do you have it mounted ?. I do not see it in the pic, if it is draging in the water it will work well but will cost you some speed and possible trim issues

      I used one of these too on my dads SV. It definately flows alot of water. I was actually going to use a little bit smaller diameter hose because I think it may flow too much and the water doesnt have the time to actually pull the heat away from the motor and ESC. It is a nice piece though.
      Many issues!!!

        Its close to the center of the V, and close to the transom where I know it will pick up water @ high speed. I've used many under-hull pick ups that just don't pick-up! And rudder pick ups that lose pressure when turning opposite the direction of the hull. As far as scrubbing speed, I've found no noticeable loss in speed from this pick-up. The drag created is minimal and may only show in tenths of a mph from a gps. For me a couple of tenths of my top speed is worth getting plenty of fresh, cool water through my electronics! And as far as handling issues, I haven't had any so far.

          I've pulled boats out of the water with hot motors and blew mouthfulls of cold bottled water through the pick-ups as hard as I could and the water always comes out hot. I doubt even the highest flowing system is flowing fast enough to pass up the heat from the components. JMO!

            I'm always worried those things would snag on something and rip a hole in the bottom of the hull.

              LOL! I guess anything can happen! Your rudder will rip a hole in your transom first!

                I have those installed on my sv (bought it used and it came with them) and was having trouble with handling this summer. After some fairly lengthy discussion on another site the general consensus was that they protruded too far down and was acting like trim tabs. I filed them down so that their profile was less than 1/4 inch at the lowest point. It seemed to correct the handling issue but I am still considering going back to using the rudder pick up.

                  Nope, almost all rudders have a break away screw (brass or nylon) so you don't rip your transom apart!!

                    Octura makes the same thing in a transom mount as well (mounts to the back of the transom, not bottom of the hull) I like that one a little better... It lets you have just the pickup below board, a little less drag with the same output...

                      I didnt know that, do you happen to have the part number?

                        Scott, those are the only ones I have added to my boats the most famous being a super Hawaii which I put 2 in, one on each side at the rear and used the Octura outputs on the transom looking like exaust ports for the disel engines. One feed the speed control and the other the motor. It functioned very well keeping the 19v SS1 very cool during the entire run. I don't race so cooling effectiveness was more important to me. The bonus is that at any speed there is no doubt that the water pickup is working!

                          YES! That's what amazed me. The flow is awesome even at low speeds!

                            Steven I'm not exactly shure but I think the part number is #71?

                              Thats a myth. As long as there is a constant suppy of water there it will cool, and the cooler the water is (faster flow), the better it will cool. Alot of people say that about cars with water pumps that flow too much but the truth is its just not true.
