"Hi guys Brent from Aus again, my 40hp merc revs up well out of the water with muffs on, sounds like it has plenty of power, in gear also, it sounds good and revs hard and responsive. When I get it into the water it starts easy enough but when I put it into gear to take off I cant get any more than about 3 knots out of it?? no power what so ever! If I try and throw the lever forward it just stalls! If I do it slowly it just putters along like a paddle steamer, I dont have the same problem in reverse though!! It revs up in reverse in the water no probs but nothing in forwards gear. NB: this is my first time out in this boat (new for me) I have looked at all the linkages and cables but I cant work them out, when I put the controls forward it has about 30% free play before anything happens which has only gotten worse since I tried to adjust the idle. Please HELPPP!!! P.S compression good, spark good and carby checked out ok for blocked slow idle jet. I need help on adjusting/ setting these throttle, idle, power, cables I have stuffed around with them a bit to much i think now i fixed the idel but the rest is kaput!! I can see they all work together in unison but i have no idea how to set them up."
