Looking for some thoughts and group wisdom regarding my engine's poor behavior.
I have a 25XP. Owned over 25 years.
It has always run the same. It's always been hard to start. Full throttle in gear has always been 2600RPM pushing boat at approx. 6.5 knots depending on condition of the bottom.
Full throttle in neutral has been 3200 RPM.
Took her out for a spin recently. Still hard to start, full throttle in neutral is 2800 and in gear 2100. boat speed 5.4 knots. Had this problem at end of last year but it might be a bit worse. Not sure.
Something is definitely wrong.
Hauled last year so shouldn't be the problem. Fuel pump ticks away as usual and I have been told (or read) that these old pumps either work or not...not in between.
No big smoke to indicate injectors.
Recently replaced both water pumps.
Suggestions??????
