Hi

Just bought a 1970 Thunderbird Cheyenne 18ft with a Mercruiser I-6.
It has the serial # 2764732 and according to listings it's a 1969 160 HP. At the same time it states 165 HP on the motor next to the imprinted serial #.

Can anyone help me figure this out?

Thanx

Mike

Re: Confused about serial #

Welcome to iboats.....:)
What listing says it is 160?.......
If it says 165 on the valve cover then that is what it is.....
The serial # is the important thing, parts wise......
5 HP +or - is insignificant.......;)
