I have a 2001 400 DB with 2 454’s.
Last weekend we cruised to an island and hang out for a couple hours and as I was backing out of a cove both engines stopped at the same time…. It took me several attempts to get one engine running again and we started our journey back on one engine. During our cruise back I tried about every 15 minutes to start the second engine and after a few attempts the second engine finally started, I was already mentally preparing to back her into my slip with one engine…. About an hour after successfully parking the boat I tried to start the engines and they both didn't start and I tried that over a couple hours…. The next day,everything worked as always, both started right away. The one thing what is really strange is that both engines do the same thing but they are completely independent from each other, right?
Could that be vapor lock? If yes would it help if I add a third blower what pushes fresh outside air into the engine compartment, close to the air intakes?
