Will not idle

[Cuerbo]

I have a 2002 Stratos 19XL with a 200 Mercury engine. I can leave the ramp in the mornings and have no problem with getting the boat on plane or getting it to idle after a little warm up of course. when I get back to the ramp and drop my partner off to get the truck I will sometomes cut the boat off. I then have a hard time getting it to idle. Once I get it to idle I start to get it on the trailer and it just bogs down and cuts off. I have to try it 3 or 4 times before I can get it up there or sometimes I just wrench it. This doesn't happen all the time but like 1 out of 5 times on the water. Any ideas!!!!!!! Please Help!

Post this down in the Mercury board and you will probably get some good info.

Mine does the same thing from time to time I change the water separator and fuel filter and its fine. Never had this problem until the E-10 Gas came out.

Im not sure if your motor has this but it could be the Throttle Positioning Sensor (TPS). I have a 225 Mercury optimax and I had to replace mine.

There should be an idle adjustment screw. It sounds like it may be idling too low. I had that problem on a Merc. then adjusted the screw and it was perfect.
