Start to Finish: Building Our 50' Skater

Why reinvent the wheel? Seatek have had a 950-1200hp diesel engine around since the mid 90s specifically built as a performance marine engine not a truck engine with boltons!
1900lbs in weight electric switchable turbos proven in class 1 for years in Skaters with Arnesons and speeds in excess of 140+.

A guy I know is working on bmw a while now pretty close to get one in a boat even thought about put a pair in my 30 cat

Couple people at Indy mentioned to me someone is looking for a pr of 1200hp diesels for a boat. Couldn't imagine who? lol. I said try one on a engine dyno at that power level for a hour, and please invite me to watch. Only problem now is finding someone to drop a 100k on that experiment. :-)
Gale Banks has done a lot of things, he has spent most of his life doing custom engine stuff, but he would be too conservative to be associated with this engine project for the high profile but risk that it might not work. And he is really busy on a few military contracts. We contacted him several times about this project right when we started it.
Tyson that's so sad to hear after all that work what speed did you see? from the video it looked like mid 70s
I really don't understand why you couldn't get 100+ I rode out in this 46 Skater with twin 750hp single turbo Seateks and it ran 100 all day with Arnesons, drives tracked straight and boat accelerated like a scalded cat.

The seateks were originally a low hp engine that are already turned up as high as they can get them and they actually advised us not to use them for the endurance,/mileage/weight/ect that we needed
When we first started this project the engines we wanted were the Audi diesels they used in the lemans race car. They were 750 hp and only weight 500 lbs. we planned on using 4 of them and would have a little better hp and mileage then in the race car by not having to meet racing rules. They would have had the high rpm and would have been set up to run on 2 if we needed so there would be less chance of getting stranded. There is a warehouse overseas that has 20 of them sitting in it and they will not sell them. I tried for a long time to get one and never got to the right person. If anyone has a high enough contact at Audi racing I would still like to get two for my cigarette gladiator and use it to do v-bottom records.

I have a very good contact within Seatek and I know the engines very well having done a number of rebuilds and modifications to these over the years. The 1200hp I thnk you are referring to is the new V12 engine basically two of the six cylinder engines put together hence the reason its twice the weight but the length should be the same.
I managed to squeeze two 6.4V10Ds into my 43 Supercat with room to spare I would have thought the Skater would have a bigger engine bay.
The lowest HP option when they started production back in the late 80s was 660hp and that was from the old 9L motors over the years they have been refined and cubic capacity on the newer engines are 10.3L
They now start at 750hp up to 950hp out of the 10.3L and if you want to sacrifice some reliability you can go 1200+
I know many Class1 teams that were well in excess of 1200hp out of the 10.3L before they were outlawed because of there dominance in Class 1 when couple to multi-speed transmissions.
Great platform for a diesel four valves per cylinder OHV single or twin turbo option, and very robust bottom end pity they weren't suitable for your application.
Good luck with your new platform I am intrigued as to the route you are taking gas or diesel?

Bit of a daft one here! I wanted to try two of these in a boat.
Transmash V12 Russian multipurpose tank / plane engine, a lot of the European tractor pullers use them.
Used to come out of Russia dirt cheap.
All aluminum 1800+ lbs 40L yes 40L twin turbo or supercharged diesel four valves per cylinder can make in excess 2000hp @ 2800rpm.
Certainly sounds a beast.

Seriously, there is no substitute for cubic inches. Right now achieving 2 HP per cubic inch reliably out of a marine diesel setup is totally doable. Even 4 or 5 HP per CI is reachable for short bursts. But there is so little data on that sweet spot in between. These 2000hp truck guys don' t care about long term reliability. Unless you count 10 sled pulls as long term. And any big marine engine manufacture is all about cubic inches for long term reliability, and low rpm pushing torque. So maybe a 3 or 4 speed transmission is the key better top speed.
As the OEM truck engine designs keep getting better, so won't the aftermarket power side. Guess who has all ready marinized and dyno tested a new L5P for marine use?? And isn't afraid to run one WTF open all day long on a dyno either. This is how you test a diesel marine engine..

Oh yeah, now I want a pair of those.. Long as they come with that same guy who feeds half a can of ether into the SC on start up... lol
