Anyone have any tricks for getting silt and sand out of the exhaust ports,cylinder head on my 88 force 50hp? I have an over heat problem sometimes; I have new impellars/wear plates, new thermostat and it's still overheating at times. I tried to remove the exhaust cover on the powerhead to clean it, but some bolts were frozen and i can't heat them without pulling the head (i think). This is the only part i can't inspect so i am hoping this is where the problem is. Any tips tricks or suggestions are welcome and appreciated. Thanks
