How to identify quicksilver repower engine size?

[ShoalSurvivor]

1999 Stingray 190LX, which came with a 190HP CARB A1 (as listed on MSRP sticker).
My engine was replaced in 2004, with a quicksilver repower engine. All numbers that I have are listed below.
He said it now has a 4bbl carb and is larger.

How can I determine if it's still a 190HP 2bbl, or if the new engine is larger, or is 4bbl, Gen+ or EFI?

thanks!


original engine SN: L332123 replaced with: 2004 Mercruiser 4.3L 225hp 4bbl Quicksilver repower SN: 90004747 (#807736R11 / 03252004)
Alpha 1 Gen II - Transom: 0L517680 Drive: 0L192679 1.62 R (1.81R scratched on top) original drive may have been SN: L40356

I verified, It's definitely a 4bbl carb.

AC Chris will confirm shortly but I think if it’s now a vortec engine you will have a little more power than 190 you used to have. Maybe like 205 or something.

Probably not relevant but but I was recently schooled that the new 4.3 reman carb engines are 225hp for some reason...but not in 2004.

 

[QBhoy]

Oh jeez. Who knows. Your 99 original was likely a vortec too.
These reman confuse the life out of me !

I don't get what you are asking. You list what engine you now have in the post.

the HP listed was based on a previous process of elimination from some web site. I wanted to know definitively what I have, and was hoping that someone would know.

Is your model number and actually in-turn it's the engine part number from Merc....Using that number brings up some pretty good details regarding this engine just by searching the model number online such as this for example, http://cmmarinedistributing.com/index.php?_a=viewProd&productId=1717

If I recall correctly a good Merc parts guy can find a parts listing using the reman serial number but it's not easy so with that here is your parts guide to help them out if ever needed...., https://www.mercruiserparts.com/4-3l-gen--4bbl-reman-1g400000-u

Though there's a bit more to read in the first link above, here's the gist of it for you/those interested,

Awesome info - thanks!

the drive is L430356, not L40356

Guys as far as I know the info given above for a reman 4.3 at 225hp....is only a recent thing. When yours was purchase away back then...it likely wouldn’t be at 225hp.

The differences with the remans are they tend to rate the H.P at the crank vs the prop-shaft like new engines do so bare that in mind too....Being these remans came with a 4 barrel carburetor for a long time now ought to of kept the H.P rating around the 225 crank shaft mark. And again the model/engine part number from years past helps tell a history of what it is/was.

The first link below also helps show a year range in question that looks bumped up a bit from the rest but that could be tide in with the MPI too.

Oh jeez I’m even more confused than I was, haha. Is that now suggesting that there is a 230 hp 4.3 ?
i know the mpi is 220hp and until recently thought that was the most powerful until l learned of the reman 4.3 carb at 225hp.
I also thought the Volvo Penta version of the same 4 barrel carb quotes HP at crank instead of prop and they claim 205/210 I think. Oh god knows.

 

[QBhoy]

What I was maybe trying to say was that a 4.3 carb reman in the early 2000’s maybe wouldn’t be 225hp. It would question the worth of the mpi 4.3 and it’s 220hp at the time. I think this 4.3 reman with 225 available now is only since the mpi version was ditched for the new in house merc 4.5

 

[Fun Times]

Believe the 230 meant to say either 220 or 225 for the V6 line.....Volvo went as high as 225 until 2015 then up to 240.

Volvo’s two feature multipoint fuel injection and are rated at 200 hp (V6-200) and 225 hp (V6-225)....,https://www.boatingmag.com/boats/43-...ndrive-options

A lot of any confusion ought to be tided up in the crank vs prop shaft rating specifications which is worth roughly around the 20ish H.P mark...Again new engines are prop rated and remans are crank rated.

reman is listed as flywheel HP, not prop HP (because it was not paired with a drive). so his 225 is accurate, assume about 190-205 ish at prop (drive dependent)
