This is a newer 4-stroke owned by a friend. Says it starts and runs fine at idle to low speeds, but stumble and stalls trying to get on plane. I have only owned one 4-stroke (big azz Suzuki) and it was flawless ... but I know that Yam 4-strokes are extremely sensitive :shock: to VST or other fuel delivery filters clogging.
Anyone know offhand what filters are in-line on these smaller Merc 4-stroke puppies so that I can guide him? He did confirm that the primer bulb doesn't go flat and ran it with the fuel cap (built-in tank) removed and got same results.
