[QUOTE="Pappy, post: 208290, member: 3278"] The powerhead has to be removed. Once it has been removed then the exhaust plate beneath the powerhead can be removed and the grommets replaced. There are two on your engine. This is an easy job. A little time consuming, but easy. Your comment on not seeing water coming from the "exhaust port" above the lower unit is interesting. There is no exhaust port above the lower unit unless you are talking about the exhaust relief just below the powerhead and lower pan. Usually no water comes out there. If however you are talking about the several holes just above the cavitation plate at the rear of the lower unit those are thermostat relief holes and you should see flow once the thermostat opens.
