My 2000 Yamaha 225 OX66 is giving me problems starting after I initially run down the lake to my first spot. When I decide to make a move is when it gives me problems starting ! Then after 5 or 6 attempts, it'll kick off running good until I make another move ! All three low pressure fuel pumps are new and the O2 sensor was cleaned . Plugs seem a little oily but the linkage appears to be intact ! Getting too much oil ?? Any ideas ?????

Have you tried starting it with it tilted all the way up ? If it will start in that position it's likely fouled plugs.
