Hi guys. I have twin 180 MercCruisers i/o engines on my 1988 Regal
277XL.
I want to order the impeller kits but my boat is not with me and I
don't know what part number to look for.
I get confused when I start looking as the ones I've found don't tell
me if it's the exact part I want.

Can anyone give me some hints on how to get the proper part?

==================

You're going to need the engine serial numbers. Once you have that
you can go to any Mercruiser parts dealer and they can look it up for
you.
