(part clarification needed)
Just replaced coolant reservoir gasket (still got a leak there at high speeds), used part #27-18272 for which parts catalog shows as the only gasket ( engine does have alum. manifold). Just looked at service manual (sku#90-44553) under coolant assembly / disassembly, manual shows 3 parts, a-gasket b-stainless steel plate c-27-97542 separator gasket. Parts catalog does not show stainless plate, do I need this plate? Engine Info 1986 mercruiser MCM190, eng.ser.no. 6925425, stern drive s no. a532009 224cid 190hp 4 cyl freshwater cooled What gasket sealant is recommended for gasket?
