I'm doing some winter maintainance on my 89 prostar 190. I took out the mufflers and exhaust hoses to give the bilge a real cleaning. I saw that it was added som sealant(looked like silicone) between the exhaust hose and the thru hull fitting? Is it necessary to add sealant there or do the hose clamps do the job alone???

All I've ever seen is the hose on the fittings and the clamps do the sealing. Maybe a previous owner siliconed it up as a precaution or something.
