Re: Mercury 225 Optimax

A bunch of the V-6 Mercurys had this problem. Check your primer bulb. Use only the "Mercury" primer bulb that has a yellow washer at the outlet side of the fuel connection. Do not use an aftermarket primer bulb on this engine. I know it's sounds ridiculous, but it's true... Send me an email & I'll be happy to send a copy of the service bulletin.
