Accroding to my OMC model number reference guide, the 2.7 Litre Seadrive is only listed as a 1987 There are two model numbers available, 27APPH or 27ASPH. Both are 1987 vintage.
Thanks for the replies. I will try to find the plate under the hood. (It's 10 degrees outside right now) Can anyone tell me what the HP is? I was told it was probably a 225.
