My opinion for what it's worth is use your own powers of deduction from what I tell you.
If you had 1 350 hp outboard engine on the same boat, what dia prop would you use? Also that prop would be a thru-hub style prop that doesn't have full blades like an Arenson prop would so it's small in area. How many rpm's of prop speed would that outboard have?
You answer those and you tell me why you need a BIG 17" dia prop on your boat?

Unless you were in the inner circles of Cummins Marine back in the late 80's you would not even know this existed!!!
Yep, 400 hp Cummins B's made by me through Cummins in the 80's. This is how my whole involvement with Kitami, Buzzi & Bonomi started. I've said in the past we had a product that could be the smaller Seatek and give Seatek a fuller range of product.
Kitami and I made a deal for AMT which is how I got equity in Super Hero and ran the racing/diesel divisons. After that deal became know Cummins had a sh*t fit and were tolerant of it for about a year and then that is how I was the only person in the modern history of Cummins Engine Co to ever be out on a black list.
Meaning every distributor in the US recieved a personal letter form the Chairman do not sell Joe Gere engines and to please advise him personally if anyone starts buying large qty's of Cummins Marine engines who had not been a piror customer. Needless to say they were ways around that too!!!
The Maelstrom pic is her with a 400hp B in the transom, notice how low it sat. A couple hundred pounds more than a 7.3L makes a difference, that was 1990. This is when, like I point out to Jassman we found out it truely is not prop but prop speed. I could turn an 18x33 4 blade with that boat and not go more than 80???? Change gears, trun a 15.5 x 24 fast and I went 90's. I took what buzzi taught me from the race boats and applied it American style and good damm it works even with an outdrive. It wasn't the Tri-Max drives that made his boats fast, it was prop speed.

29Firefox,
Nipendenso's, I have to try and find what they flowed at, may have that somewhere???
Injectors - no shims, here is what we found with shims, the higher the pressure you cut the time (chronogical) that the injector has to deliver fuel. By doing that you retard the timing a little as well so if you advance the timing to compensate they you end injection too early.
The higher pressures put load on the pump cam as well. The inline pumps didn't bother them much but the rotatry would push the head to side and score the barrel. Those couldn't run anything above stock and we lower some injectors to make less head pressure on the Standadyne's
I understand fully the thought behind higher pressure better atomization but every impedance will cut flow and you deleiver less fuel reagrdlesss of pump settings. The stock injectors worked well and never burned one up?
