1992, Wellcraft LXH, twin 7.4L mercuriser set up, thunderbolt IV ign. Both engines 4,500 RPM at WOT.
Last weekend STBD engine would only reach 4,000 RPM at WOT Port still making 4,500RPM. Changed cap, rotor, and cleaned all engine ground wires. New fuel filters. Carbs are clean in throat, flame arresters cleaned, starts well, idles well. Need ideas where to check next.
