OK guys, see if this sounds familiar: Not always, but ocationally about 1 hour into the ride when I have my Mercruiser 190 4cyll opened up, when I trim she tries to cut out but only when I am hitting the trim switch. When I let off on the switch the motor is fine. Works almost like a cut-off switch. :confused: Any thoughts?

WOW !! that's going to be one of those "shake,pull,wiggle" jobs..somewhere there's wires shorting together...it could be anywhere from the keyswitch/trim button, to the trim pump/engine areas...GOOD LUCK.....

Check the alt output when you trim up.
