Congratulations John and team. That is an extraordinary amount of work you guys got done!

You all all deserve a few beers and a lay down I’m sure.

Anybody know detroit's well? The dang thing runs great, starts first turn, not too much smoke.... but... starboard side at 1200+ rpm blows nasty black cloud and won't go over 1500. From idle to 1200 they are remarkably clean for two strokes, and the power is super smooth. On the cummins I would think aftercooler and then turbo. Is it the same on these things?

Check and cycle the shutdown flap, sometimes they'll get accidentally tripped and may not close completely. Actually likely as much work as you've done! If they were running fine before, it's got to be something simple. Running smooth makes me think it's not an injector or rack issue (but it could still be). Fuel starvation could also be a possibility but sounds like an air problem.

Huh. I will google that That sounds like a winner, i hope it's that. Cummins don't have those.

Congrats on the launch!! Had a chance to view just before the big day, tremendous achievement under less than ideal conditions. Well done Capt. John and hats off to your entire team

I would check the shutdown dampers as well. Looks like you did alot of work on the flybridge. Typically there is a cable with a T handle running up on the port & starboard side of the helm. When pulled they shut the engine down to prevent the engine from running on its own oil in the event of catastrophic failure. They are connected to to flaps or dampers on the air intake side of the engine by the same cable mentioned above. If they get pulled they have to be manually re-set at the engine. FYI dont pull them when the engines are running above idle or you could mess something up big time. They are made for an emergency only but need to be used occasionally to prevent them from seizing up. I exercise mine with the engine off. I am trying to attach a file that has the manual for the air intake section of V71 series engines. If it doesn't go through I can email to you. I would assume you have 71 or 92 series engines.

I have the 6-71s. I think this is the problem. I'm having trouble finding where the shutdowns were at. I was cutting on the tower when the guys took the fly bridge apart. Isaw the cables but just assumed they were chokes or trolling valves, and I didn't realize what those cables did. Yep, messed that up. Anybody got a picture of where those cables connect? I guess I can figure it out tomorrow just by looking around, but if somebody has a picture or can give an explanation, It'll cut down my learning curve... I guess I have to find where those things went and put them back in.

John I emailed you some information that should be helpful. If it didnt come through I can text you pictures of the applicable pages of the shut down flaps
