No exhaust through prop hub

Post by catalacmarc »

Just bought and installed two clean used model 6G8 Yamaha 9.9s. Both started right up but the first one only ran a few minutes the next time and wouldn't start there after. That is not the wierd thing. What is wierd is that there is no exhaust through the prop hub? Water was also not going into the leg, just going out the normally unused second water outlet on the motor base. A real rip off, gravel in the fuel pump, carberator assembled wrong and a leaky cracked gearbox. Good news and the reason I haven't tooed it back on the guy's lawn is that the leg looks mint and compression is 140+ in each cylinder. Next stretch of good weather, I'll pull the motor and see what is going on with the exhaust manifold. Any thought?
