    Mariner 8HP Carb Photo? Hole in Casting?

    Attached is a photo of an engine my brother is working on. There appears to be a hole in the casting that fuel spills out from. Can anyone tell from the photo if this hole is supposed to be there?

    1973 7.5 Mercury 75 Cooling Issues

    This motor has survived 25 years of abuse since being relegated to communal cabin use. Of course the impeller (water pump) disintegrated and the engine ran hot on more than a few occasions. The impeller was replaced by a one-man shop on my sister's dime. When I finally got to inspect the work, I...

    Need To Pull Flywheel On Swedish 4HP Outboard

    I recently had this motor walk into my shop. It's an air-cooled SBM 4HP made in Uppsala Sweden in the 70's. Has a Bing carb and a direct drive shaft (i.e. no reverse). Just like the old OMC motors, you rotate it 180 degrees to get moving backwards. Seems to be in pretty decent overall condition...

    Photo of Steering Setup for Older OB's

    I thought since there seemed to be some interest regarding aftermarket options of steering kits for older outboards (especially to replace cable & pulley systems), I thought I would post a shot of the installation I did. As you can see, I mounted the transom plate directly over the existing...

    '63 Rude 40HP Needs Low Speed Needle

    Don't ask me why. Just suffice it to say that my low speed needle is shorter than it once was and now I fear that I may likely not be able to lean it out. Kits generally don't include this part and I've done some searching but if anyone knows where I can get one I would appreciate the info. I do...

    '63 40HP Evinrude top cylinder no fuel UPDATE

    This engine was running pretty decent until it suddenly lost some power. Initially I thought it may be a coil problem since there were some accessories tied into the ignition system. I've since rewired the entire system to isolate the ignition and replaced the plugs, points and condensers and...
