Help ID Volvo Penta Engine and Outdrive

[rjbergen]

I have a 1997 Four WInns Horizon 240 with a Volvo Penta 5.7L Gi engine and a Volvo Penta Duo Prop outdrive which I believe are original to the boat. The prior owner bought the boat in 2000 and owned it until Aug. 2014. I am trying to determine what service manuals I need so that I can work on them and order parts correctly.

My background research has led me to believe that the engine and outdrive were actually produced by OMC with the Volvo Penta label during their joint venture based on the T in the serial numbers.

My engine has a serial number of T01303033 I believe (hard to read the tag) and I haven't quite gotten to read the product number accurately yet.

My outdrive has a serial number of T0813439 and a product number of 3868441. I've attached pictures of the data plate on the outdive. Is this a Cobra SX Duo Prop? Is it equivalent to a Volvo Penta DP-S?

Can anyone help me find more details as to what I actually have here? I'd like to buy service manuals for both engine and outdrive, but I'm not sure which ones to buy. I think it may be this manual (?): http://www.iboats.com/Volvo-Penta-St...-view_id.55655 Does that manual cover full service for both the 5.7L Gi engine and the outdrive (whatever model it turns out I have)? Or do I need this manual because they were manufactured by OMC: http://www.selocmarine.com/product_detail.php?item=26

Thanks. I've seen that before. That doesn't help me much right now as I can't get to the engine tag until the shrinkwrap comes off in the spring. I'm more interested in the outdrive for the moment. I need new anodes to start and would like to know what to order.

I pulled out the sheets that the employees signed for each step in the build process and for the engine, transom plate, and outdrive they noted the serial numbers, but the manufacturer and product number slots were left blank :facepalm:

My boat has a 1998 Volvo Penta Duo Prop DP-SM Ratio 1.95 and a 5.0L GL engine. My outdrive tag looks pretty close to yours, sans the difference in the serial numbers. The drive and ratio were interchangeable with the 5.7L GL and GI blocks. I have pics posted under the thread " DP-SM Seized to Gimbal". Take a look and see if they look the same. If so, you will need the anodes for the DP-SM.

Thanks! Do you know if the engine and outdrive use the Volvo or OMC repair manual? Since everything is labeled Vovlo Penta, I want to say it would use the Volvo. However, the serials have me wondering since they're prefixed by the T which is OMC's signature.

I bought the Seloc Volvo Penta Stern Drives 1992-02 Repair Manual. I also downloaded the Owner's Manual from Volvo Penta's site. It says not for use in North America, probably due to the OEM status with OMC, but everything matches to a "T".

Here is a chart that may help as well. The insert hyperlink feature doesn't seem to work very well. You may have to copy and paste into your browser.

That's what I was hoping for. Thanks!

I've looked at this chart a lot. I knew from the looks that it was a DP-S_ drive. I just couldn't tell the difference between DP-S, DP-S1, and DP-SM. The DP-SM just looks to have a more detailed drawing. But my drive looks exactly like a DP-SM.

You likely have the "LK" or "NC" model drive. Both are DP-SM. There should be a sticker up on the engine that has the part number on it.

Just because the boat is a 97 does it mean the drive/engine is 97.

For example, I have a 98 boat with an LK drive.

For example, I have a 98 boat with an LK drive.

Don't the LK/NC/etc. letter designations determine the manufacture time frame for the engine? I know they're found in the engine model number.

When searching for my engine in Volvo's database, the only 5.7Gi engines that comes up in the proper time frame are the 5.7GiPLKDCE and 5.7GiPLKECE. That leads me to believe I have an LK version which fits because it was produced from 1996 - 1997. The boat was a 1997, but manufactured early in 1997 so it's likely that the engine was actually a 1996 production. It's also unlikely that it would be a BY since that was 1997 - 1998 production and likely started after my boat was built. It is possible that it's an NC which was 1995 - 1996 production, but LK seems more likely due to production dates and the fact that no NC model is listed in Volvo's database.

So far, my conclusion is that I have a 5.7GiPLKDCE or 5.7GiPLKECE engine with a DP-SM outdrive. However, the serial numbers are clearly not Volvo Penta numbers, so it appears that my combo was produced by OMC under Volvo's name? Are my engine and outdive identical to those produced directly by Volvo Penta?

Those years were the Volvo OMC joint venture years. They are identical.

I tried to look up my serial numbers for my engine and came up with a big goose egg as it is an OMC number. However, the model designation, mine is PBYC, definitely converted over on the Volvo site. Mine is a '98 on a '99 model year boat.

The important letter you need to use are "BY"
