Paul i know why you dont like the injection is because of the electronics and the water but my engine compartment / bilge doesnt see any more water than my truck does and it has way more electronics than my boat does with none of the issues that i am having now with my boat

i really think that both of us are having the same problem and it is a fuel pump issue since i have already changed all of the electronics from my old engine to the replacement and nothing has made a difference and it just keeps getting slower which could be from the fuel pump getting worse

You might have some other issues as well. I would start with a compression check on the motor. But, if you want to see if it will turn anymore RPM...put a 19 inch prop on it and go run it to see what happens. If it is the same as with the 23 inch...then you DO have issues.
