When I installed a water pump on my 89' Evinrude 150 XP there was a part I am calling the exhaust adapter (It looked like a baseball home plate and was about 5" across on the top and went down to about 3" at the bottom) It sits between the midsection and lower unit. My question is about the rubber seals, the are torn is that going to be a problem? I didn't have the replacement part so I just put it back together but if I need to I will take it back apart and put in new seals. Also what is the actual name of that part?
