I have two 6bta’s that have about 4k hours on them. One is running, starts right up, little to no smoke, has newer aftercooler and turbo about 3 or 4 years old. The other is non running, have complete engine but separated bolt ons (was going to swap long blocks). Everything for engines is included but not the gears/trans. Both engines ran great and made full power and rpm. The stbd engine was showing signs of severe blow by and lost oil pressure. Both are still in the boat so the running one can be shown/tested. Hoping to get them out in next week or two. Looking for 12,500 for the pair or 8500 for the runner and 5000 for the non-running one including all bolt ons (aftercooler, turbo, heat exchanger, gear cooler).
