Normal
Started and run a ton of Yamaha 4 strokes. They start flowing from the indicator as soon as the block fills not when the thermostat opens. One easy check though is to put a toothpick or wire up into the indicator nozzle and clear it. If the pump is good it should start pumping at this point.Secondly.....if he is running it on a set of muffs that are square or rectangular instead of round it probably will not pick up water as readily as the good round ones. Burned paint around the cylinder head is never a good thing. Is this where the block/head shows paint damage or on the cowling. If it is the cowling there may have been an electrical fire under the hood. Check all wiring. Ask for receipts for work performed. Ask if the engine has ever been serviced, do a compression check, etc.......
