    1979 70hp Mercury Propeller Issue

    I was wondering if anyone may know why my propeller stopped rotating at the end of last summer? Or what to look for?

    So the other day my prop stopped spinning on my 1979 70hp Mercury. Full throttle still doesn't spin, but the engine sounds as if it should be going full speed. I did some research and first thing was broken shear pin. So I took off the prop but did not see a shear pin or where it would even...

    Upper Motor Mounts Help!!!

    My upper motor mounts on my 1979 70hp Mercury are busted. Motor works great, but I cant afford to put $800 into the engine to have them replaced. The mounts themselves are only $140, but it's the 5-6 hours of labor that is the expensive part. I've had it suggested to me to try and cake on JB...
