"Hi all, we have a 4.3l OMC with Cobra drive. First off, thanks for your previous help. We went out on Saturday and after leaving the Marina, about 10 minutes at 6 knots, we accelerated up to 22 knots @ approx 3,400RPM. 5 minutes later there was a clunk / bang as if we had hit a small log. All Ok for another 3 or 4 minutes then the same noise again. Still wasn't sure then the noise again. Slowed down to idle and the drive seemed noisier than usual. Kept it at around 1200RPM and motored slowly back to marina. This took about 30 minutes. If I tried to go any faster the noise would be back. At the marina the boat would still go in and out of forward and reverse. Any ideas what could be wrong? With limited mechanical ability is there something simple I should look at or should I just call in the mechanic?"
