    Sportmaster water psi guage

    I just purchased a sportmaster lower unit and dont see anywhere to hook up a line for a water psi guage. How do I hook on up to it? Any help would be appreciated.

    I believe your going to have to tell the forum what powerhead you have and your going to pick it up from there .

    Its a 1995 Mercury 225 3.0, I am changing from a 25" mid to a 20" mid and also picked up a sportmaster lower unit, but do not see a place for the hose to hook up for the guage. My stock lower unit had one just forward from the water impellor housing.
