So not a good weekend we left port with all tuna gear at the ready. Just getting on plain heard a bad knocking from the motor and oil pressure dropped. From the nature of the noise I would say it spun a bearing. This has 730 hours and has been faithfully serviced. Oil level is clean and full only used yamaha oil and filter. 500 hour service was done at the dealer. I am sure this will need a long block. Have any of you experienced this and what was the final cost?? 2006 f250 txr 730 hours 2007 2310.
