As JWB states, you can remove the thermostat temporarily, BUT if the thermostat is faulty, replace it as the engine demands a thermostat.

If all of the above suggestions sill result with a lack of water pressure........

the area of the lower unit that the water pump impeller plate rests upon is notorious for being eaten away at the rear portion slightly on that model. If this is the case, that area will require to be built up and surfaced with "Gray Marine Tex" or "JB Weld", something of that nature.
