Thanks all for the help. I got some 1/2-13 shorter bolts. I think when I was checking the fit of the original bolts there was some paint in the new motor's bolt holes and I was scared to use some force on the bolts since I wasn't sure if I was returning the motor. Good news is, the shorter bolts...
I had ordered the 18-5907 and it doesn't seem to fit, the bolts dont slip through to mount. Am I missing something on this or is this the wrong part. If I get the 18-6949, any idea if I would have the same problem?
So I have an old 1977 MCM 470 that I have removed from boat (need to do some fiberglass work) and placed it on a pallet. I semi-rebuilt the engine by cleaning and then replacing intake/exhaust manifold and gaskets and a carb rebuild. Prior to taking engine out of boat, I tried to start it and...
Hello,
I have a project boat, 16ft 1978 hammond with mcm 470 and a mc I outdrive. I noticed there is some metal missing on the lower portion of the outdrive. Refernce included pictures. Is this something that if not fixed will cause damage to the internals of the outdrive or can it be left...
Yeah I for sure wont be running anything lighter than 18 for the same reason. I'll probably push that up to 16 just as extra caution.
The 20ft length you menton, is this round trip or one way? The 54ft I came up with (need to re-measure it anyway) was a round trip so from source through switch...
I'm also wondering if I'm measuring or calculating the distances wrong. An example is the switch panel to/from the fuse panel. Measured 18ft, routing from port side battery area (in stern), to transom, across transom, along starboard rail, and down to panel. I had 94+24+16+16+36+16+16=218" =...
Hello,
I am working on rebuilding a project boat and I am currently planning out electrical work and wire costs. The boat is a 17ft 1978 Hammond with a Merc 470. I measured out the round trip (fuse panel to dash switch control to nav light and back) for the light and it calculates out to about...
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...
