Hello all, first time poster here. Sorry if this topic has been covered before. I am looking for an OEM service manual for a 1978 Merc 470 engine (MCM 470). I have found some stuff online for one, but the sites look fishy to me. (911 manuals, aservicemanualpdf, etc.). I can't find any websites that seem legit. I know finding one online for a pre-internet era engine is a longshot, but has anyone had experience with any of those sites and/or know where to find an OEM service manual?
Thanks
Thanks
