i have a 2003 Crownline with a 5.7 Volvo Penta GXI. ive had this problem for 3 years. it will chug between 2k and 4k RPM's, the first 2 years i could put seafoam in and the problem would go away. it ran fine at low RPM's up to 2k and if it was ran over 4k. now we put 4 cans of seafoam in, ran it for about an hour at 4k RPM's then idled for about 30 min. when i went to take off it would stall out. ive put in new plugs and plug wires, new roter cap, cleaned fuel pumps, still dies when i give it gas.
