A friend of mine has an older Honda outboard (egg beater as I call it). No #'s on the data plate...all rubbed off. The cover says Honda 75 which I'm assuming means 7.5 hp seeing as how it's dam sure not a 75 hp haha. I'm needing to rebuild the carb, put in a new water impeller and I have no service manual to do so. Rebuilding the carb will be easy seeing as how I've grown up with carbs and they're very simple. The problem I have, possibly anyway is that I'm not sure how the lower unit drops off to service the impeller. Any assistance with identifying this motor and/or links to how to get to the water impeller to change it out would be great!!! Thanks
