Dr Faz..thanks for the great input..I would like to hear Fortunate's response too..i was curious for several reasons..but one that really stands out would be the amount of space the 8's take up in a smaller engine room..I would have thought straight 6's would have been a more "servicable" choice from getting around the engine especially on the outboard sides.
we have the engines in our 53 hatteras and have a little over a 1000 hours on them and only have positive things to say. we did our research before the repower and are very pleased with the service and output we get from the engines.
they are fresh water cooled
These however are tweaked by Yanmar to peak at 900 HP with Torque that doesn't quit.
I looked at the Cat C18's, too heavy to much fuel burn, I looked at the Volvo D12 800 HP, and service is tough to come by. I looked at the Yanmar 900 HP V-8's and they were just right.
Rather than get into a discussion on Cat, Cummins, Volvo, Man, and the virtues of all of them, let's just leave it at;
We did studies on all 3 engines that I was considering and the best set up for a package of this size was the Yanmar.
Plus I'm a believer in the company. Teaming up with Scania was a great move.
Scania makes a great product.
Plus they fit so well and 16 liters of twin turbo charged V-8"S look so nice.
Canyongear, There's plenty of room to access the outboard sides of the engines by going around the front. Here's a picture of the front of the port engine. Of course a fat man will have a heck of a time getting by. But seriously there's plenty of room to get my 6' 215 lb body by. And there is a lot of room on the outboard sides.
If you look at the 2nd picture down from the top on this post you'll see the room available on the outboard side. The fact that the engine room height is so high, it's easy for a tall person to slide their legs by and bend over at the waist as you slide your legs by the front.
I don't know if you noticed, but the boat was designed to be able to take a lot of water in the cockpit. That's why the steps to the engine room were made so that we have 3 step risers high before water could begin to enter the engine room.
The scuppers we're using are in this picture. As you can see by the size of the cleats the scuppers are quite large. If I'm not mistaken they have a 3 1/2" diameter face with a flanged pipe that ends with 2" diameter hole.
Engine room steps:
In this picture you can see that they are recessed in each corner and once the teak deck is installed the scuppers will sit slightly below the top of the teak similar to a bathroom drain, this way there will be no puddles to dry and leave residue. The cockpit deck is cambered towards the back corners.
If we get too much water back there, then we'll just open the cockpit door.
Dr. Faizel emailed us and asked for some feedback on the V-8 Scania as we are are starting our second full season with the engine in the charter boat Karen Lynn. We built the boat ourselves and went with the Scania both as a result of their reputation as a bullet proof engine and because we wanted a 16 liter V-8 as it fit in our layout really well.
After 2500 hours we couldn't be happier with the engine, the support from Scania & Bell Power (the east coast dist.), and the ease of maintenance.
Things we really like about the engine:
1. Ease of Maintenance- The Raw water Pump is up High on the rear of the engine. Really easy to check or change the impeller. The Oil filter, Fuel filter, and Alternator are right on the front of the engine and couldn’t be easier to access. All the connections with the exception of the engine zinc’s are really easy to get at.
2. Alternator- Huge 24v 140 Amp alternator is high up on the engine (safe if we blew a water hose) and can handle a huge amount of load.
3. Oil Centrifuge- Because of the centrifuge we get extended oil changes of 400+ hours without compromising the life of the engine. We have taken regular oil samples and the reports keep telling us to go longer between changes!
4. EMS System- Really good system with all the information you would need in an easy to use display. It was easy to marry up the Scania control system with Twin Disc’s controls which we also think are unbelievable.
5. Fuel System- Very clean and accessible. Incredibly easy to bleed although after the initial startup we have never had to bleed the system when changing filters.
6. Fuel Consumption- Right there with the best in class of the electronically injected engines.
7. Great Documentation- All the installation, parts, and owner’s manuals are straight forward, clear and consistent.
8. Smooth and Quiet- What else can you say!
Below are some pictures of the boat and the engine. It is not at the same level of finish as the other boats in the post but it is an awesome fishing machine. Fortunate One and Dr Faizal you will be very happy with this engine.
Aw man that's a sweet downeaster. Quite the set up.
I'm suprised more people don't use Scania products. That engine is a real workhorse in europe.
What's that engine rated for? 800HP?
I know that Yanmar tweaked the injection system and if I'm getting a correct read on the pictures it looks like they've increased the turbos. But never the less it's still a Scania with some High performance parts.
