I have a 2003 225 OX66 (VX225TLRB) (400 hours on motor). I have continually fouled plugs when I have to idle any distance or about every 50 hours. With the price of gas I now hardly ever open her up and the fouling seems to be worse. The last set of plugs I had were completely fouled after a fairly long 2-3000 rpm jog in heavy waves with a heavy load. Also did quite a bit of idling prior to this looking at the graph for some deep fish. I maybe got 10-15 hours out of this set. Changing the plugs solved the problem. Also replaced the thermostats, although when I checked them they were working fine. Checked all the low pressure fuel pumps and one was leaking a little. Re-built it. The others were fine. I checked the oil linkage and the lever was about 3/16 inch away from the stop pin with the butterfly completely closed, although checking my 20 hour check receipt the dealer said he re-set this. That was back in 2004, so I'm wondering if the dealer really did adjust it, or just said he did.
From what I've read on this board the oil linkage lever should be against the stop pin with the butterfly closed. Is this the correct adjustment? I checked my buddies this weekend and his was where mine was originally (3/16 away from the stop pin) although he fouls plugs every 40-50 hours also
