Looking for any guidance on correcting a delayed throttle response on a 2001 Mercury 125HP. Motor is on a Ranger R71. Motor runs great aside from being a few seconds delayed when pressing down the throttle at the console. (Press down to full throttle...pause pause pause...motor comes to life and launches me into plane). Nothing noticeable in terms of sound from the motor.

 

Any suggestions would be appreciated!

Hello and Welcome to Bass Resource ~

Unfortunately I'm not mechanically inclined enough to a offer any useful advice.

Plenty here are.

I would advise that you address / correct that throttle issue. 

If that throttle pause also becomes one the "sticks" - it could be very dangerous.

I could be mistaken, but I believe that was still in the 2+2 era of 125's. (also included 90's and 115's) What that means is that when your motor rpm's drop below 2000, the motor drops 2 cylinders to save on gas while idling. The problem is on something like a bass boat, that RPM range is right when you're taking off so the problem you're experiencing is because as you hammer down, you're running under half power until the 2 other cylinders kick in somewhere between 2000 and 2500 RPMS. There's really nothing you can do about it other than live with it. As long as you're still planing out quickly enough it's just something to get used to. If not, you could try running a smaller prop, or increasing the size of the ventilation holes just to get your rpm's up over that threshold quicker. Honestly you're probably better off just living with the hesitation.
