Hello!

I am under contract to purchase a 1995 Tiara 4000 Express with twin Cummins 6CTA8.3 engines. The engines passed survey, however, I am wondering if there is any knowledge about how to rebuild these engines in-frame if needed. Is is possible to do an in-frame rebuild on this boat, without cutting out the deck?

Best regards,
Richard

I have a 98 3500 express with the same engines and I think it can be done... I have seen some posts of people that have done it on other models,, the express has a large engine room (larger than the open) and since the 6CTA is a wet sleeve engine, it could be done for some repairs (hoping that your block is in good condition).... I would ask in boatdiesel, seaboard marine or the cummins powered boats group in facebook to be 100% sure. If you would have had 6BTA's then it would be a no..
