hey, im trying to ream my spark pluge opening on a 1976 25 hp evinrude, you guys have already helped me so much,... but in the process of removing the head cover,....ive screwed up a gasket,...its not the head gasket,... its a small triangular shaped gsaket just above it,... i have no clue what the purpose for this is,... but there are three bolts that hold on a cover shaped in a triangle just above where the spark plugs screw in,..... the part number from iboats.com is 0385789 and they say it is not available. ,.........any other options,...or would i be better off just getting a "blank" gasket and cutting it to fit? you guys are the best thanks for any imput!!!!!!!
