I have twin 7.4 Marine Power TBI. Both motors run off the same tank. Port motor will run up to 4,000 RPM Starbord won't maintain 2900 RPM. Have changed filters, fuel line and pick up tube. Any suggestions what to try next??? |

George, it sounds like a similiar problem that I had. You should have a low pressure & high pressure fuel pump. Check to make sure the relay's for those pumps arent bad. |
