[QUOTE="Incahiker, post: 182832, member: 4777"] Make a long story short, got a 4 hp merc. and had to replace the impeller and took the carb. apart and cleaned all jets and other metal parts real good because they were gunky as you could get.. It starts right up and idles as good as you can get. The problem is when it is in idle I can goose the throttle and it will rev up really good to it's full power without hesitation, but when I put it in forward gear it go's to about mid point picking up speed and power then after that it just kinds stays that way, its like I am not getting full power of the motor when I am in gear. If I keep playing with the throttle back and forth it will start to plane for a second but then lose that power, seems like it is only running on half of what it's potential is. It idles like a champ though and puts along great, but I am definitely not getting full power.? Any ideas on what it may be? The carb looks brand new after I cleaned it, from what I understand it may be an air intake, fuel intake problem? Any other inputs would really be appreciative. Oh ya, it is pushing a 1432 lowe jon boat if that helps at all. Thanks in advance. [/QUOTE]
