hey folks, I have twin 4jh4-hte's in a 38' catamaran. Port engine had water in fuel tank, replaced the deck fill, removed water in tank, replace filters and 4 injectors. first test run still couldn't get over 2300 rpm.. came back in and freed up Turbo, so now spinning freely. Checked Stbd Turbo and it was also stuck so freed it up and it's now spinning freely. drained both Raycore fuel/water separators. And went out for another test run.... NOW both engines will not get over 2000 rpm under load and black smoke out the exhaust. At the dock rpm's go up to 3300 rpm no problem and no smoke. I've ordered some fuel treatment K1000 and going to try that, hasn't had any since last summer. ???? any ideas. thank you in advance. Capt Mike
