2007 350 EC low power ? 350 MAG

Mbmike

Boat seems to have half the power it normally did have,  very low hrs on motors maybe 150hrs,  thought it was a fuel filter issue so just replaced fuel filters and small screen in fuel cooler.  Took the boat our just seems like its missing under loan on one motor and the tach is very erratic.   Anyone have similar issues ? Boat in the passed would easily plane out , run top speed of 31mph now only can get 15?   Bottom was just scrubbed have it done 4 times a year so don’t think its from the bottom growth.   Was thinking maybe replace wires, plugs next but it idle’s so smooth along with at dock I can rev up each motor with no noticeable miss or hesitation 

anyone ?

Spark plug(s), wires, cap, rotor.

Do you have DTS (Digital Throttle & Shift)? If yes, check to make sure you are not in "Dock" mode. Been there, done that. And cheapest fix you can get. Push the button. :-)
