I’m not pretending to be smarter than anybody. But On a boat this size I don’t think you are able to insure it w/out an auto fire suppression system. If you have the QSM11s the exhaust manifold/turbo housing operates at 900+ degrees under load, any of the fluid hoses get a leak under pressure and contact the exhaust And I think you are going to want a suppression system that does not require you to open the hatch, or at least gives you the option not to.I'd like someone smarter than me to explain how important they are on a diesel boat. ABYC doesn't require them and requires four B-1 extinguishers for your size boat.
