My 1993 175 60deg V6 tends to misfire a couple of times and then cut out at higher revs, usually fine at lower revs (under 2000). Seems to be gradually getting worse (ie more frequent) Will usually re-start straight away, occasionally have to crank a few times. At other times will run fine. Have cleaned out tank, float bowls and engine fuel screen and replaced cartridge filter and line from tank to filter. Had thought it was fuel, but now wondering about ignition. Any advice gratefully received here in sunny Oz
