We have had a strange experience with our starboard 454 Crusader regarding fuel supply. 2 mechanics have worked on this issue. The first finally figured out that all of our times stalling at sea was due to a fuel supply issue. Taking off the pump, they realized that the mechanical rod was not functioning correctly off the cam shaft. Frustrated with trying to repair it, they capped the old pump and installed a new electric fuel pump. Our new mechanic came to try and get the motor to idle better, replaced the carberator and realized the electric pump is feeding too much fuel to the motor, thus making idle very difficult to achieve. He took off the plate and said, I can get that bent rod out of there and replace it. He did...said you're back to mechanical...much safer.
Well, we took her out this weekend and just like before, she lost power, and the starboard motor died.
Could there be something wrong with the lobe on the cam shaft, thus causing the rod to not operate fast enough under load? If so, can that be repaired? Should we just go back again to electric? At least with electric, she was fed properly and though idle was a little fast, we were able to go somewhere
Thanks for your help.
