motor is on a 1990 19' panteraII basscat. Just bought the rig. Fixed iat sensor, had injectors cleaned, deleted the 2 little bowes on port side. Forgot what they were called. Set timing at 23 wot and deleted vst tank. Have a stainless steel avenger 24p. Seems i am only getting 3200rpm out of motor. Thats trimmed out wot. Running bout 58-62mph. Don't seem right, should buy knew tach or different prop?
