Q:
Is this the correct part to fit a 1965 Mercury 500 SN 1762112, if not, what is?
A:
No this is not the correct base. You need 46-39531A1 which we do not offer unfortunately.
Q:
I have a 65hp Mercury. Model number 4383738. The body assembly looks like this one but is white plastic. Will it fit?
A:
Based on your serial number this should NOT be the correct pump base assembly. You should need 9-43301 or 18-3423.
