    Ultra 150 straight head fittings?

    Ok I am a bit stumped here? I took all 3 water fittings off my Ultra 150 to install straight fittings. They are all 3 5/32 id. I thought only # 1 was 5/32?

    I thought the one (front, I believe) was smaller to force some water through the exhaust system. Too large a hole would dump too much water overboard and overheat the exhaust.

    I just looked at a parts diagram, the front fitting IS different from the other two.

    But what I am saying is all 3 fittings are the same 5/32id. Only the front one uses a 1/4 hose and 2 & 3 use a 3/8 hose.
