So I ordered a new boat from Malibu 2020 23 LSV. The engine on the order sheet was for a M5Di. Fast forward 4 months and I am just getting to winterize my boat. I had the dealer do my first oil change at 15 hours. S0 I was looking for my plugs to drain but the pictures didnt match the owners manual. So I looked at the engine cover and realized my engine is the Monsoon 6.2L 450 versuds the ordered M5Di. Im not really sure what to do but it seems I received the wrong engine and this was an older engine. Now im not sure that older is always worse but not sure what to do?? Any advice would be helpful. PS I finally found the drain plugs but they were in a total different location that my owners manual stated because it is a different engine.
