I have a 1986 sea ray sundancer 270 with twin 4 cyclinder mercruisers 3.7 liters.. i just bought the boat 2 weeks ago the seller said both motors where rebuilt ( not sure no papers ) and boat sat for about a year an half.. On the port side engine when i go to throttle up at times it will bogg then stall out and a few times when doing 6mph at 1500 rpm it stalled out.. but runs great once up to high rpm.. i replaced the cap, rotor, points, condencer, plugs, wires, fuel filters, acc pump and rebuilt carb and and put new gas in but im still having the problem.( having the problem whilein the water) timing seem to be on point at 8, now im not having the problem with the other engine which both use the same fuel tank. can anyone please help me on this? also i am new to this site and not sure if im in the right place..
