I was inlake at 35mph and I push a little bit more the throtle and suddenly my in line 1150 115 hp 1973 goes almost at full rpms you can heard running. I cut it off right away and wait like 5 minutes to turn it on again and it run good at iddle. As soon I put it to forward it moves good and as I move the throttle again to try to got back to shore it run again so high in rpms. Thanks God at iddle I arrived to shore.<br />Please help me out, the boaters around shore saids that the rubber hub its broken. Its true?<br />Thanks in advance for any help!!!
