I have twin 07 250HP Four Strokes. Purchased new. From the begining I have had problems with fuel showing up on the oil dip stick. Seems to me that Yamaha continues to put band aids on for a fix. Would like to know if anyone else has experienced this problem. If so can you share with me what was done to fix the problem.

"T-Stats have been changed, has failed leak test twice (currently 15% port & 20% starboard), I do not baby this boat, but I do not run the dog Sh--out of it either. Ran boat for the FIRST 75 hrs with bad t-stats. Makes me believe that rings never seated properly during brake in. Now have almost 300 hrs. Trying to get info to use to get Yamaha to do something besides putting band aids on the engines."
