I had a problem with a previous boat, engine dying at higher rpm's. Turned out that there was a filter on the fuel take-up, in the tank, that was partially clogged. Once I cleaned it, the problem went away. With my present boat with a 3GMf engine, I had a problem with the transmission not fully

Good points Francois, I have meant to take a good look at the prop and probably do need to send it off for reconditioning. I know the bottom is a little dirty and so is the prop. But even when everything was freshly painted I still had this issue. It starts up very easily which makes me think
