The starboard motor had a malfunctioning water psi sensor yesterday. We unplugged it and made the day.
Boat was sluggish and that motor wouldnt get over 3500rpm while the other motor ran hot. Boat was doing about 19mph.
Today, replaced sensor, fuel filter and separator and plugs in starboard motor. Bay tested. Still kinda sluggish but better. Ran it up to 4k rpm but the boat was only doing 22mph. Usually at 30mph with that rpm. The port motor was running a little hott again.
Any thoughts ?
