New Drive from Volvo, has prop infront of drive
 

Check this out I wonder if it could be used in a high performance application?? Click on the more info to see a picture.

I meant in a newer designed boat :D

Its supposed to be really efficient, there is no way to trim it however.

Re: New Drive from Volvo, has prop infront of drive
 

Boating Magazine recently did a test (March 2005 issue) of two Four Winns 378 Vista Cruisers, one with conventional V-drives, and one with the new Volvo IPS drives (backward pointed drives mentioned above). Both boats had identical power (375 hp Volvo D6 diesels), layouts, and displacements. The IPS boat ran a top speed of 42 mph, the V-drive 37 mph. At a cruising rpm of 3000 the IPS boat ran 33.5 mph, got 1.2 statute mpg giving it a range of 335 miles, and shoed 80 db at the helm. The v-drive boat ran 31.5 mph and got 1.2 mpg giving it a range of 317 miles and showed 83 db at the helm.

So, the new drives were a bit faster, a touch more efficient, and offered a quieter cruise.

I saw this at the London boat show.

Theres a pick of us looking at it close up it here...

The most worrying part of it is when the "giant hook" catches the "giant under water obstruction", it parts your boat at its cleverly made weak point.Then sinks to the bottom, and theres another ooportunity to make another online pruchase from VOLVO.

Surely a coiled up teather betwen the the two parts would be a good idea? (for owners)

May be Mercruiser will produce lower unit reversal adapters, so as not to be out done?

Re: New Drive from Volvo, has prop infront of drive
 

My $0.02: IPS is a small step forward but still has all the disadvantages of a stern drive so nothing revolutionary. Too many moving parts, too many cogs to turn which means power loss and inevitable reliability problems when you get into high HP and torque stuff. Like with a stern drive, I can see drag being a problem and vulnerability of those drives strikes me as a major problem. So thanks, but no thanks. Not for me, I'll stick to surface drives. It'll probably work for express cruisers but it's definitely not for HP stuff. Having said that, I do believe that ZF Marine's Ring Drive is a better solution for express cruisers as it combines the performance advantages of a surface drive and saves just as much space as IPS does vs. conventional V-drive.

Re: New Drive from Volvo, has prop infront of drive
 

yeah, and that idea to make the drive-hull connection a weak point so that the drive falls off without ripping a massive hole in the hull if you hit something at speed is a bit naive. Thanks very much guys, how thoughtful! Unless you're gonna sell me replacement drives for $100, I'd like my hard-earned drives to stay with me. And somehow, those pods don't look cheap at all. One very expensive fuse...

Arneson Drop your prices.

Mercury try to be just a little bit, more adventurous.

GOD give me just a little more money. :-)

Check the SEAKEY anti theft system fron VOLVO,it is discussed in the theft recovery article on the VOLVO site.

Re: New Drive from Volvo, has prop infront of drive
 

Then you are in agreement with Volvo, who designed it for cruisers. Not for high HP, high speed boats.

No probable about it. It has proven itself as a reasonable alternative to V-drives and rudders.

As far as choosing between having the entire boat sink, or the lower of the drive sink. I pick the drive. My buddy has a donzi with twin Volvo 270 drives. His Dad hit a log in the river on a dark night, hard. The drive absorbed the shock and separated. He marked the location of the mishap and he returned to the dock on the remaining drive.
Called the insurance company and they paid for a diver. Brought the drive up and it was inspected and re-installed on the boat. It is still on the boat to this day.
That was like 1987. Those are the smoothest shifting drives I have ever seen.

Can't hate Volvo. I would consider the SX drives on a "slow-fast."

Re: New Drive from Volvo, has prop infront of drive
 

Trailering could be interesting

Re: New Drive from Volvo, has prop infront of drive
 

don't they also make a fully composite drive?

the forward facing prop was not designed so much for the us market, but for overseas where there aren't so many "shallow" spots

the prop hits first in any collision, the skeg gives no protection.

These new drives are suposed to be much easier to manover a crusier at the docks and around the marinas!

I spoke to one of the salesmen in Miami, and walked me through it.

The steering is electric powered. So if you have a power failure to both sides (one will still steer if one side fails) there is a manual over ride on the top of the unit to steer. But all one has to do is make sure both are pointed streight, and then just used the shifters.

Here are some pictures I took in Miami.

Re: New Drive from Volvo, has prop infront of drive
 

I also asked the salesman if Vovlo had plans to use this design in a stern drive high performance modle? He replied "No, the high performance market is far to small for Vovlo to get involved with"

I can only asume he doesn't have a clue about other Volvo products, dork.

Re: New Drive from Volvo, has prop infront of drive
 

Just take a bravo 3 lower and spin it around 180 degrees!

Re: New Drive from Volvo, has prop infront of drive
 

I think that most of it is composite. Especially the things that have contact with the water. Some internals are still conventional, I think. Could be wrong.

Re: New Drive from Volvo, has prop infront of drive
 

The IPS drive is bronze, and w-a-y strong. The new D6-350 deisels make a lot of torque. Primary applications are 40-foot express boats - the advangates don't really show up until 35-40 mph and up. Very much for the US market. And they've been impact tested. Severely. Let's just say that any impact that would tear the bottom unit off of the boat would punch the shafts, struts and rudders right through the bottom of a shaft-drive boat (and sink it).

Super - do you have any pictures/links to the ZF ring drive? Sounds neat.

The Volvo composite outdrive is called the "OX" series and is available with gas engines up to 502 cubic inches. Pretty much a conventional layout.

C spray, go to http://fbdesign.it/ringdrive.php

That will give you a bit more info.

BTW, what Ernie said. Where I boat, if IPS falls off, that's it. If you're more than a mile offshore, depth is already 500+

Re: New Drive from Volvo, has prop infront of drive
 

Ohh... where I boat it's like 3 feet deep.

When we have problems we get out and walk.

Re: New Drive from Volvo, has prop infront of drive
 

As stated in the articles and in some of the above posts, these drives are designed for express cruisers, not trailerable boats, not GFBL boats (if you don't know what that is, check out the Lake Winnie speed woosies thread!), not fishing boats, and not snailboats.

Re: New Drive from Volvo, has prop infront of drive
 

And go backwards!! Props sping the wrong way if you simply did that!! have to run around in reverse to go forward... since there are no left hand or right hand bravo3 drives or props.

Re: 3 wishes
 

To what? We are already less expensive than Mercury, what more do you want?

Re: 3 wishes
 

i bet most people have the misconception that your drives are more expensive due to the boats they end up on... i rather have asd's than pay merc for sixes and my next cat will reflect that.... :cool:

Re: New Drive from Volvo, has prop infront of drive
 

Ship Shape TV did an episode on it, its running all week on Fox Sports Net http://www.shipshapetv.com/

definitely not for performance boats but big gains in speed with small yachts.

I think the engineer's were drinking that day :D :D :D I wonder if mercury is gonna buy the patent,then discontinue it?? :eek: :eek: :eek: tripps
