I figured out how to post new message I think. I sent Live2fish a message reply. But any how, if someone can tell me about my clunk in lower unit upon take off onto pad let me know. It only does it when I first accellerate to get on pad. Sounds like prop is slipping and I am hitting multiple stumps. I checked everything and nothing is loose. I replaced water pump because it sounded like it was sucking air. But now has gotten worse and is really clunking multiple times. My prop was bent by DAH 2 years ago and is in good condition. I don't want to open up lower unit if I don't have to. Anyone have this problem before? Could the timing be off or fuel be getting cut off? Any suggestions would be much appreciated.
