I have an '89 Evinrude 40hp on my Tracker. While running, I can top out around 27mph with myself in the boat and only lightly loaded. I'm not terribly disappointed in the performance, but the tach only shows 4500rpm at WOT. I'm not sure that I trust the reading on it, as the gauges on my boat were all in relatively poor condition when I redid the interior.
Additionally, I replaced the lower unit and prop with one from another boat as the original was damaged pretty badly. I think the current prop is a 12 x 11 3/4.
Any easy tricks to gauge the speed of the motor while it's running? I know that props are very dependant on conditions, but what are other people with similar setups running for props?
