I really need a service manual, can anyone send me a pdf?? drbenson@live.com is my email. motor is 217-5888, serial 152728, 1973 model yes?
I cleaned the carb, changed lower unit oil, and check the impeller (was good). The motor starts easily, idles fine, but when I engage the prop and increase throttle, I get an distinct "bang" in the lower unit that occurs every 15-20 seconds. I filled the oil in the lower unit to the top letting the vent assist the oil to migrate down. I'm wondering is it overfull? If the gears froth up the oil and being incompressible...... The motor runs great with prop engaged at idle speed, only at higher rpms does it get noisy.
