Hey folks looking for a little help, got my boat in the water yesterday, it starts great idles perfect i let it warm up, idle out of the channel then put the throttle down it took off real good for a few seconds then bogged out... I started it back up and idles fine but when i engage it, it bogs out. If i use my warm up lever and get ideling good and fast when i engage it it will move slowly, and feels like it wants to go but then bogs out again. New tanks, new plugs, new fuel. So my car buddies who don't own boats are all saying its dirty carbs, I know my basics and am learning as I go so I thought I'd ask here for more advice from people who have had this issue before. Thanks for any help...
