Currently still sixes although i have been chasing some Arnesons locally.

I have a total of 314 gallons (257 main and 57 forward) so I can go about 600 miles. But I usually start with 150 gallons run it down to 40 or so and put another 100 in unless I am going to the Bahamas for a week then I fill both tanks. I get better MPG running 50/50 water/Meth but what I save in diesel I spend x4 in Meth so its not worth the $$$ and hassle for MPG alone, I thought about using the forward 57 gallon tank for a dedicated water/meth tank but for the limited amount of time I could really use the extra 30hp (at WOT) its not worth it, I mean if I am going 55 or 57 does it really matter? I may reinstall the water injection system and just set it up to run when I get over 1100 EGT and it will last about 7 hrs off of the 40 gallon freshwater tank. (175ml/min x2)

But in your case couldn't you add more fuel which normally would cause an EGT problem but offset it with the water injection, apples and oranges I know, my engines only make 325hp each

thats some great fuel consumption
Some day i would love to build a diesel boat.

Ok on with the count down.
We need to go vertical a f350 rim provided a stable base


H

we go after the forward cone which is threaded internally not like the
aft cone which is external.
Here is the slide hammer with adapter

here it is

the pinch plate is now exposed along with the bearing housing

it is now easily removed

here is the flip side the pinch plate and bearing housing is shown here together

as we move forward we are ultimately removing the diffuser housing so we can machine it with the scallops similar to the bearing housing shown above
here is the bearing which we need to remove next

look closely you can actually see the marks where the scallops are going
i am pointing to the crush seals which need to be replaced at reassembly
