Engine problem

I have an envirude 40 hp on a bass tracker I think it is an 88-89 model. This weekend I was running at full throttle at about 5000 rpm and then it started to spike to 8000+ rpm. From then on I could only run about half to three quarter throttle without it spiking. Any thoughts.

Sounds like your hub on the prop might be slipping............
