1OK on MTU 8 V 396 TB 93 Is this rebuild time?

Sounds like they're ready for their second round of W-4 scheduled service. Go to MTU's web site and read the "W schedule" for the time frame and proportional depth of the service / rebuilding at the set forth intervals. These motors aren't for the weak of heart or pocketbook to own and operate.

Modern power would add $500,000 minimum plus the cost of new iron to repower due to girder modifications and drive line changes not to mention exhaust and plumbing mods that will be needed to accept new or different model motors. Its always better to either rebuild or have re-manned same model engines especially on a boat that will never be worth the investment going in.

Yes we did. I'm now a couple of months in on a medium sized repower that has the scenario listed above. Girder mods, drive line etc. etc. Rarely if ever will you be able to repower with a different manufactures engine package and keep your drive line angles from one to another and that's just the tip of the iceberg down the line for ancillary attachment's. $400,000 for the iron and another $500,000 for the modifications and putting the machinery space back together to pass classification survey.

J,
I like your "pluck" but I'm sorry to say that two Caterpillar Marine C-32 Acert or any new C-32 motors of any rated output in bobtail configuration will cost more than your stated amount for the "total" repower above. Add another $28,000 for Z.F. 550-A gears or slush boxes of your choice and everybody and their brother would repower in North Carolina especially if Ring Power was giving such deep discounts that would allow the labor costs for removal of existing DD's along with wiring and plumbing to off set costs and then install new power with labor to plumb & wire the new iron. I have a group of clients and naval architects that will beat Jarrett Bay's door down for a deal like you've described above.

So "all in" what would be your estimate for this Jim Smith repower?
