hmmmm marine motor

[88beast]

i saw this on tds
"new here, would appreciate any input. back in the early to mid 90's, the 7.3 direct injection navistar international T444E (truck form) motor was marinized for marine use by marine corporation of america (mca) and marketed as the (inboard) M444E stardec series / star powr (correct spelling on stardec/powr). there were three hp versions: 300/315/330 (all turboed)"

so how do they make such high power is it the mystery cam weve been looking for ?
anyone have one of these?

The E in T444E is electronic, it's a powerstroke. I've heard part of the reason marine engines can make so much power is that they typically have no cooling issues due to unlimited cooling water.

That is the answer rite there. there is no problem loosing heat + water cooled manifolds and water to air aftercoolers (if aplicable).

ya that is psd aint it i didnt even notice that i just saw 444 and assumed he was right (i know what assume means oops)

I think there may have been a marine version of the IDI? I cant say I have ever seen one.. I have never seen a marine powerstroke either though.

There have been a few posts on it here. I believe the engine spins the opposite direction, which means the IP and cam is different.

Mercruiser made a marine 7.3 IDI.

HERE IS A LINK to the parts used and they are illustrated as well. Don't see any power rating though.

Its 1994-1996. So i don't think is an idi

do powerstrokes have precups in the heads and the same kind of injector pumps as us? just because it is a 94-96 marine motor doesn't meen it will correspond with the same year truck motor.

No, no precups on a PSD. Looking at Mercruisers parts listings their 94-96 7.3 diesel engine is definitely a 7.3 idi with a turbo. From poking around, it's looking like their top power rating was 270hp, which is definitely interesting. This is the turbo they used:

Looking at the prices on that website makes me glad I dont have an IDI boat!


Gheesh!

$3 grand for an IP???

 

[88beast]

that looks similar to an hx35 maybe ill see similar numbers on my turbo
this is interesting we gotta find out if the cams different and if it is maybe type4 can get one made
