    Compression test My guess is the motor is just wore out, because it should rev easy in neutral

    4 blade prop

    Get a new Tach because your motor is not turning that fast. Going from a 3 blade to a 4 blade with the same pitch your going to drop RPM around 200

    Mercruiser Alpha 1 G2 Trim (probably dumb questions!)

    Could be a pump problem but I would look at the cylinders first because Like most, folks raise the drive till it stops. If folks would bump the down after it stopped going up, this would release the pressure and ease the seals Pressure is higher going up and less for going down
