Most likely there is some debris, sand/gravel, grass stem, etc in the discharge hose or "pee hole". A water pressure gauge is a good idea on these lakes, especially if you fish shallow and pick up a lot of trash in the water pick-ups.
It usually takes up to a minute or more (sometimes two or three minutes depending on rpm) for the water to come through the system when the motor is started, so don't worry if you don't see water right away. And it is true, many motors don't have a strong spray at an idle. Check and make sure your outlet hole is clear of trash, and if it's any consolation, I run a 250hp Merc motor, and mine almost always stays clogged with grass, trash, etc, and sometimes don't spray any water for weeks. I go by my water pressure gauge.
