I’m working on a 79 checkmate predictor
I put a 1998 mercury 150 efi 2 stroke and I’m not sure how long it hasn’t been running but I rebuilt all the fuel pumps and I was getting about 35 psi on the fuel pressure gauge as well as replacing fuel filters and separators and new gas and lines. all spark plugs are new as well
it starts up first time and idles and revs up great out of water but when I put it in the water for the first time the other day I felt a slight shaking under load at idle and when I tried to give it throttle it bogged down and and shook more and wouldn’t plane
