    Default cooling question

    I've been running,adjusting, and timming the engine while on the trailer and sitting at the launch ramp. Question I have is,,,,can I cool the motor with just the impeller in the leg, or do I need both pumps. It seems that I have a lot of water delivery to the second pump. My system has water in from the leg, to the pulley driven pump, out the top and over the side. I'm running dry exhaust.

    Default water cooling

    I do not believe there is a pump in the leg. there is only the seawater pump on a bravo 1. Of course there is recirculation pump on the front of the motor in stock form.

    Default cross over tube

    I was wondering if I could get away with running just a cross over tube and the alphas pump. After all, my V drive only has the one pump. My water comes in the engine, thu a thermostat and out over the side.

    Yes
    Sound like if you have two impeller pumps and an alpha drive then someone added the second pump or you had a motor transplant and they pulled a motor from a boat with a bravo drive and left the second pump on it? The second pump is not needed and the recirc pump can be eliminated with the crossover kit.
