Re: what year is my 100 hp johnson OB

Hi,
The only 100 hp V4M that I found is a V4M-12 and that waas a 1966 model. There were also 2 90 hp V4M's one in 64 and the other in 65. Double check the 115 to make sure it's correct. It could be a V4ML-12 which would make it a 66 long shaft.

Re: Re post due to typo.

I would assume that someone switched the hood.

Model number V$M-10S, ion the OMC Model Guide identifies it as a 1964 90hp Johnson.

BTW.... The last digit is not a "5", it is a "S".

You should be able to pick up a parts book for that model from someone here or on eBay.
