Help identifying my VP engine

[Pete1burn]

I have a 1994 Larson 194 LXi with a Volvo Penta sterndrive. It's at the dealer right now getting some general work done, but I asked for the serial number. What they gave me is 411506964. I tried searching for that on the VP website and didn't get anything. They said it's a 1994 V6 with 190HP. It also has a duoprop. I couldn't even find a 190HP engine made by VP in 1994.

Any help is appreciated. Thanks.

Don will Id it with that, I believe....

It's no doubt a 4.3l Chevy based motor...

I'll have to get it this weekend when I pick it up. I thought they gave me the whole number, but it doesn't sound like it now.

The 411506964 is part of the serial number, but either they or you left out 1 number, it's supposed to be 10 digits long.

Re: Help identifying my VP engine

Was at the boat this weekend. There are two stickers on the plastic cover but they are faded and really hard to read. What I could make out was 41115D6964. That D might be a zero. I also saw 3868003 or could be 38680D3.

Below that was what looked like TSK DP-S and "drive DP-C".

Any help is appreciated.

Those numbers are for the outdrive, not the engine. And not even for the DP-C outdrive.
IF you can't find some numbers, take some pictures.

Hi Guys,

The thread in the link below may help, the original poster there includes some good pics of the drive. They have a 1993 V6 with the 290 style DP-A duoprop drive, they call it a 431B, which kind of fits in those years.

My basis for my thoughts on this come from my own investigation (and confusion) as I researched my boat, a 1991 duoprop with 5.7 4bbl GM based engine. I found that mine can be called the AQ271C or the 570/DP. Both of these show up in the manuals and even the prop guide from Volvo. I was able to get an owner's manual for mine, there were 2 choices and are identical, one from AQ271C designation and one from 570/DP designation. When I order parts I use the AQ271C as all those parts and drawings fit. Mine has 570 on the flame arrestor cover. In the thread below I have AQ570 typed in but it is really only 570/DP as the designator in the prop guide and such

Seems like the 431B is the 4.3l "marketing" I.D. from those years, the AQ designator might be AQ205A as that is a GM V6 with 4bbl. The AQ175A is a GM based V6 with 2bbl.

"Those years" is what I call the crossover period when Volvo went with the SX drives and phased out the older AQ drives, like 1990-1995. It seems from 1995 and after you could go by the year somewhat.

94 was the first year for the SX and the joint venture between Volvo and OMC
He has a 94 and says the drive is a DP-C which is not the SX type drive. Which leads me to believe it's an earlier model engine than 94. which as we all know it's not uncommon for boats to have an engine package a year older than the boat, since they are manufacturered by year that goes Aug. to Aug or some such thing. But not Jan-Jan like boat hulls.

Without pictures or correct numbers it't just a bunch of guessing. there are several different engines in the 43X series, and it's pobably not an AQ model for the simple fact that the AQ in the designation was dropped after 1987.
