tell me more tell me more!!!!!!! funny you say that,,, cuz about 10 mins after i caught the biggest air i ever have in my boat i pulled into a cove to jump in the water and cool off.. Started her back up and took off, i was cruzing at about 25 mph and i heard a weird backfire puff / caugh sound.. i imideatley looked back and saw a big puff of smoke coming up from under the motor. The smoke shot out both sides, left and right. I shut it down right away.. the breathers were smoking pretty good too. pulled a valve cover off to check out the rockers to see if i loosened any up and they seemed ok.. Started it back up and it idled normaly. Went to take off and with in 2 seconds of giving it gas it went bam,crack shabang. powwwww... Shut it down once again right way. and got towed in. pulled the cover off yesterday and there were broken springs all over.
