volvo penta OMC cobra

[txbandit44]

Looking at I/O's and have a few questions.

I have read here and there that volvo penta parts and OMC cobra are the same for a stretch of years. Is this true? If it is does this mean I can still get parts for a OMC cobra?

Are VP parts expensive compared to MC? What about availability?

Aside from the GM v8 and v6 did VP use a volvo block? Like the ones in the cars?

What is the advantage to the DP series drives?

A few are the same, don't expect a 93 or older Cobra drive to have any parts that are the same. The SX style drive by both Volvo and OMC during the joint venture of the two, were the same.

Are VP parts expensive compared to MC? What about availability?

Drive parts are more expensive than Alpha I parts, but also completely different. Not sure how you compare the two. Compared to a Bravo III, I would say the prices are about equal and in many cases less for parts for a DP Volvo, the SX would be about equal to or less than a Bravo II also.
Also understand that the Volvo drives are Cone Clutch drives like the Mercruiser Bravo drives. The Volvo drives do not use the dog clutch like the Alpha drives, or pre SX OMC Cobra drives.

Aside from the GM v8 and v6 did VP use a volvo block? Like the ones in the cars?

Not any more. They used to use the 4 Cyl. Volvos years ago, but not since about 91.

What is the advantage to the DP series drives?

If you ever own one, you will NEVER go back to a single prop. I'm talking Volvo here, not Bravo. The difference is night and day for anyone that has run both.

And a set of props how much for that double prop on the volvo. 1200 dollars or more for props VS 600 for bravo 3 props.

Re: volvo penta OMC cobra

Is the cone clutch a better set up I assume. I will have to look into this. For the beginner and some one that will most likely do all the work myself. What would you recommend I look for Don? I am on a budget looking at mid 90's and older boats.

Re: volvo penta OMC cobra

Most Cobra parts can still be found.
MC are obviously much more common and readily available.

Re: volvo penta OMC cobra

Budget minded, Bayliner cuddy cabin 18' 3.0 mc motor you will do close to 45 and sip gas while doing it. Cruise at about 30-35 if conditions permit ride nice and a mid 90 boat and trailer under 3000. Probably now under 2500, with trailer.

I know i'm not don.

The prices are probably similar for new parts.

As far as "new" parts availability, that would depend on how close you are to your Favorite Volvo or Mercruiser dealer.

Most all parts dealers stock or can easily and quickly get "normal" maintenance parts for both (including out of business OMC) (even NAPA)

There's probably FAR MORE Mercruiser dealers in the US than Volvo but I don't know the number.

Ebay is a good indication of used (and some new/old stock) parts/unit availability.

A few minutes ago, a "Mercruiser" search in "Boat parts, Accessories and Gear" produced a little more than 2100 hits.

A "Volvo" search produced 653 hits.

There's usually about 3 times more Mercruiser "stuff" than Volvo "stuff" in the Ebay boats parts area on any given day....

What is the advantage to the DP series drives?

Essentially more efficient coupling from prop to water because of more blade area in contact with the water..... results in about 50% less "slip"

A "twin prop" drive will give you far better holeshot and acceleration.

(I went from a single prop OMC King Cobra to a Bravo III with little or no HP change [Actually 10 crankshaft hp less!] and the results were something short of spectacular)


Cheers,

Rick

Re: volvo penta OMC cobra

Thanks everyine this is great info. Cheifalen funny you should bring up your bayliner sugestion. There are 3 here locally that I am interested in. I dont know where it came from but I thought bayliner was crap? But it has been sugested I look at them? Maybe its just the outboard boats that get a bad wrap for transom rot.

Re: volvo penta OMC cobra

some years of the bayliners were prone to deck and transom rot.
seems they tried a different glue specification on their wood laminates and it took a few years of production to find it did not work.
however still to this day bayliner is known as a cheaper entry level boat and is typically rigged with cheaper components and cheapere wiring harness's.
couple that with the fact that most bayliner buyers could not really afford a boat and did no maint they tended to get ugly in a few years.
so yes I have my share of bilgeliner jokes and for a few years they kinda were.
but with care they can actually be a decent hull for the money.
somewhere around late 93 early 94 Volvo and OMC strendrive went into a joint venture, somewhere around late 95 early 96 volvo bought out OMC completly.
so some cobras were badged cobra SX and all parts and tooling were a JV number.
the old dog clutch omc cobras were not bad just had quirks that a lot of techs could not handle.
the JV and later SX stuff worked very well.
as far as the engines volvo sold the automotive side to ford about 96 or so and Volvo penta,later volvo, simply used either Ford blocks or GM and about 95 Ford withdrew completly from the marine market which is why all we get today is marinized GM stuff.

Re: volvo penta OMC cobra

Lots of wrong info going around about Prop prices for DP props in this thread. Earlier chief again jumped into unfamiliar territory with wrong information.
On ebay you can find all sorts of deals with anything, but his statements said that Volvo DP's were $1200, which is way wrong, since OEM props from here at iboats are about $750, which is about what dealers sell them for. and iboats don't even sell Bravo III props. You can find them at the Merc site http://www.mercurypartsexpress.com/us/bravo-three-c192.html for $650 for the front prop and $750 for the aft prop. You will also notice that the Bravo props are SS only, no choice for aluminum. If you want Volvo SS props, then they are about equal to the Bravo III.
Again, you can go to ebay and craigslist and find used in both types for a lot less.

Not by me

 

[chiefalen]

Re: volvo penta OMC cobra

Was wrong it's 1499 for a set of duo props.

Went to the top of the page and looked it up maybe you should have.

 

[Don S]

Re: volvo penta OMC cobra

Post a link, not just a price. You may be talking the wrong props for the wrong drive. Volvo's have many different kinds of DuoProps, because there are many different types of DuoProp drives. Mercruiser has only one.

Did i get it right?

 

[Don S]

Re: volvo penta OMC cobra

So, you searched the web and found where you can get ONE prop of a DP set for a B3 at a low price. But, you didn't do the same for Volvo.
Sounds fair coming from someone that knows nothing about DP drives.

 

[HT32BSX115]

Re: volvo penta OMC cobra

Well,
Never-the-less, this is interesting, since this appears to be the first (non-Mercury) company providing new SS BIII props for far less than what Merc sells them for....

competition is great!

 

[chiefalen]

Re: volvo penta OMC cobra

Ok have it your way sign of a small man. Gave you the chance to admit your wrong.

Show me a set thats new for less and prove me wrong.

You were the one that posted i.boats had a certain price.

I know how to count.

"but his statements said that Volvo DP's were $1200, which is way wrong, since OEM props from here at iboats are about $750 "

Were you wrong in the above statement also??
