ok i just posted the same thing on where it says 40 merc but im not sure if you guys will see that post so I will write it once again,Today I took the boat out ,I changed the bulb and the boat stalled every ten minutes at 1,500 rpms again while idling through no wake zones,i guess im in process of elimination now,next i was going to bypass the fuel seperator then go to the anti syphon valve if it really has one...this is frustrating trying to have a romantic night on the water and you gotta pump a bulb-lol,joke but not really it did happen i took my fiance out,anyways please help with any feedback in the mean time i will be eliminating possibilities
