'94 Merc Black max 200 hp. My motor frequently takes 10-20 seconds to produce water out of the tell tale after I start it. I run the boat in salt water and flush the engine regularly. I replaced the water pump last year and still had the same problem. Motor runs cool and fine other wise. Can anyone tell me if this is normal or should I be concerned. <br /><br />TIA<br /><br />pete
