    US Engines (Pros/Cons)

    I am thinking about doing a long block repower for my 7.4L/Bravo 1 (300 HP). US Engines seems to have a really nice looking price for a long block with over 100 more horsepower and 25% less fuel. Now I build my own race engines for circle track racing, and typically, the more HP, the more fuel...

    1993 7.4L Mercruiser / Bravo 1 (300 HP) 600 CFM or 750 CFM Carburetor

    I have a 1993 7.4L Mercruiser/Bravo 1 in my Crownline 225 CCR. The current carburetor on it is a Weber 4bbl. I would like to change the carburetor to the new Edelbrock marine carburetors model number 1409 or 1410. They are 600 cfm and 750 cfm respectively. Can anyone tell me which one to use...

Attitude wise, the bow of the boat seems to be...

    1993 Crownline 225 CCR Water Tank????

    I found that at the base of the cabinet containing the sink, there is a what seems to be like a 3/4" clear hose protruding through into the storage bin under the adjacent seating area. I put this hose into a pitcher of water, actuated the manual pump and it sucked the water from the pitcher and...

    Water Tank 1993 Crownline 225 CCR

    On my 225 CCR, it has a galley sink with a manual pump, however, I cannot find anywhere on this boat where some kind of water tank would be. Without trying to pull out a sink that doesn't seem to come out with any ease to trace the lines, does anyone know where the tank is located on this...
