I have twin 6.2L with Bravo 3 sterndrives 2.2 ratio. Hill Marine 4x4 props new. 200 hours on motors. Replaced plugs, cap and rotor plus fuel filters in spring 2022 and the boat ran great.
Mid-summer 2022, I clipped a rock with the starboard drive which caused minor damage to the props and a chip out of the skeg. There was a drastic change in fuel burn on starboard side (+3gph vs port) which I attributed to the damaged props.
At haul out, I noticed that the gimbal ring was cracked so I replaced both transom assemblies. I also replaced the props and had the skeg repaired. When I mounted the drives, I swapped them so now the repaired drive is on the port side.
After all that, the port motor is now burning +3gph vs starboard. Also, the port motor won’t get above 3700 RPM when accelerating where starboard will do 4000. Once on plane both motors perform fine. I can only assume the drive is the cause but I can’t figure out what/why.
Thank you for any insights.
