OK guys, give me some ideas what to have checked. I've noticed a little loss of power, and a drop in RPM's I'm getting just around 5000-5100 rpms, where I used to get about 5600. My top end has dropped a little, down to around 61mph.
This is a 1991, 150 Faststrike, on a 1988, Ranger 364V.
Have you checked the compression? Spark plugs? It sounds like it may need a power pack.
Burning the candle at both ends.
The things Robert posted would be a good start.
See if you have any fuel leaks at the carbs, these motors....over time will need to have the carb bowls replaced or sanded to make the gasket surface flat again.
