I have a 2003 speedster 200 with a v6 mercury engine 2stroke. I bought some bombardier xps synthetic oil from dealer but after reading my boat manual it says I should use mercury or quicksilver oil. Will it harm the engine if I use the xps synthetic?
It does not have the TC-W3 certification that is required by the Mercury. Go to Walmart, or your local marine dealer and pick up a jug of the Quicksilver TC-W3.
