502EFI stalls at idle/ HELP

[Nick Verburg]

My boat stalls when at idle, but only once the engine is hot. I have a merc 502efi. The dealer said that this problem is common with the 502. It may be common but there must be a way to fix it. Has anyone had this problem before? What was done to fix it?

well for proper feul atomization you need it warm.a few years ago they used to put a burner if you will in the center of the intake manifold on the heavy duty trucks which was located inside the intake of course
