In some cases the number is on the engineside of the manifold and may be hard to see prior to removal. The numbers from your existing parts then can be matched up to thenumbers in the cross reference and index on pages 67-74. Some may have no number at all, making it difficult, but not impossible toidentify. This is where model number information is handy. Find your engine manufacturer in the table of contents and match up to themodel number information on the top of the corresponding page.When years are listed, this does not refer to the year of the vessel but to the year the engine was manufactured. In many instancesthe motor can be several years older than the boat.The installer, whether a hired mechanic or the boat owner, must be aware of the importance of proper gasket installation at the riser tomanifold surface. Water leakage at this point is virtually always a gasket seal problem, not a defective part (however, water leakage atan improperly installed gasket will eventually damage the iron parts in addition to allowing water into the engine). Please read our techtips for installation of gaskets.Understanding the plumbing of a manifold may help in the installation and reassembly of your manifolds and risers. Familiarizeyourself with the OEM service manual and make sketches or photographs of your plumbing system prior to disassembly. This mayavoid problems with the installation.Remember to drain water from your manifolds and risers prior to removal of any of the pieces. Failure to drain the parts can result indamage to your engine due to water ingestion.Do not alter or modify gaskets. Order the correct parts for your installation. Remember to paint your manifolds, risers and elbows.The cast iron parts come with a coat of primer and must be top-coated for protection against external corrosion.
