I have a 1974 225 HP OMC GM based engine. Question is, does any one know if this is a 305, or 350? I don't know how to tell and I need to order some parts for it. Any help is appreciated. Thanks
Re: Does any one know what displacement a 1974 225 OMC is?
Actually, it's a 307.
Best thing to do when ordering any part, is to first look up the OEM part, then use the OEM number to make certain any aftermarket parts cross to the OEM number.
Go to the link below, and follow the links to your engine and model number. http://epc.brp.com/Index.aspx?lang=E&s1=16fbab16-4a27-47f7-afc4-339b4c1a74d6&brands=ej
