I need to replace the impeller in my 2005 40 hp Merc. The serial number is 1b035396. I cant find that number on iboats or marine engines.com I think the part number I need is 47-85089-10 or 18-3057 However for a 40 hp 3 cylinder some call for a 18-3057 or a 47-85089-3. On ebay I see where the 47-85089-3 says it is for a 15 to 25 HP Merc.

Can anyone tell me what part number I should have and tell me why I can't find my serial number?

Thanks

Checked at Marine Engins .com showed the numbers you have fitting you motor for the water pump impeller. 47-85089 &18-3057 & 0775466 should all fit your motor. They also list your SR# under a 2005 40HP 3 cyclender as the numbers they list is starting numbers an up.Crowley Marine only list a water pump repair kit #821354A2 that fits your motor. With it you get the gaskets, impeller, ware plate, and tube seals.
