Hi all, new to the forum but really hoping someone might be able to help me out. I have just bought a boat with a Mercury 850 Blue Band that seems to run smoothly on idle and fine when you engage reverse gear, but as soon as you engage forward it sounds as though the gear is jumping in (rather than a smooth change) and 9 times out of 10 it causes the engine to stall. I've stripped down the carbs and they seem to be fine and clean, adjusted the idle to the correct speed, and adjusted the gear and throttle cables as per the Seloc manual that I have, but still no luck. I've read various threads about carb, electrical and reed valve problems that cause a stall, but I'm wondering if this might be a gearbox problem as everything seems to be fine when you go into reverse? Really hoping someone might have an idea as I could do with avoiding a costly diagnosis from the dealer.
Thanks,
Stu
