    1975 Mercury 7.5 HP Service/Shop Manual?

    Does anyone know where I can get a shop manual for a 1975 Mercury 7.5 2-stroke? I found a Haynes/Clymer, but was looking for a Mercury manual if there are any out there. The Haynes is kind of sparse. Definitely nothing on the shift lever/sector gear. Online search pulled up nothing but an...

    1975 Mercury 7.5 HP shift lever issue (stuck all the way down past reverse) and proper linkage/lower unit alignment

    I purchased a 1975 Mercury 7.5 2-stroke (serial # 136279) a while back with a folding boat (12'Porta-bote).

    1st Lake test - What should I check ? (OMC 3.8L Stringer 800 - 1983 Beachcraft 180S)

I got the thing running on a spare tank (clean/new) with a remanufactured carb with muffs (yes, lower was dropped). I have verified that the thing shifts and prop spins. I also have a spare electric...

    I cant remove the bowl on the fuel separator on my (new to me) broke a** 3.8. Is there a spin-on replacement that will fit the same mount? (some look like it in pics... but not threaded/need nut) I would like the best/easiest replacement parts for future maintenance. My old 28' Sea Ray had a...

    OMC 3.8L Fuel pump works! No fuel dumped into the carb though - replace?

    So after completely dousing myself and the back of the boat with fuel.... I have determined that the fuel pump is working (running off of bypassed fuel tank and separator... external tank with primer bulb and in-line filter). It sounds like I need a carb rebuild or to clear out something in...

    Just acquired a 1982 Beachcraft 180S with a 3.8L OMC and Stringer 800 (checked model numbers, etc). I did not test the boat on the water before purchase (yes, I know...lol). It has a few issues. #1 - starting/fuel issue #2 - tilt issue - not coming back up #3 - screw holes in transom #1 -...
