    MCM 470 Starter Shot? Replacement options?

    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...

    MCM 470 Starter Shot? Replacement options?

    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?

    MCM 470 Starter Shot? Replacement options?

    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.

    Cosmetic damage to outdrive or replace it?

    I haven't taken the prop off yet, but it looks like the deepest part of the damage is either just before the prop seal or about a 1/4 way in.

    10AWG for a 1amp nav light? AWG Overkill?

    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...

    10AWG for a 1amp nav light? AWG Overkill?

    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...

    Where to find OEM Service Manuals - Merc 470

    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...
