Identify this Volvo motor! :)

[Modemagic]

All the Volvo guys out there.... Identify this motor and outdrive please.

The plate on the Outdrive says 'Volvo 280'.

Re: Identify this Volvo motor!

Well, the stern drive (outdrive) has the model number on the back. It looks a lot like my 280, but I can't read the numbers in the picture.

I also suspect that the engine model number (and stern drive) are located on the port side of the "bell housing" on the engine. Possibly starts with AQ.

Just saw that. That is the model of the stern drive.

Yep, like AQ145 for example...

Re: Identify this Volvo motor!

I know this is not part of your question, but I see an automotive fuel filter, this should be changed to a marine fuel filter/water seperator.

I also see that clear plastic hose not hooked up to anything. I believe that should go the bottom of the spark arrestor, you can check your manual to see the exact location. That hose is just incase your fuel pump diaphram develops a leak, the fuel will go to the carb, providing it is a marine fuel pump. The way it is set up now, it will just pump fuel into the bilge and possibly go KABOOM!!!!

By the way the drive model should be on the drive, and my guess is that engine is a AQ 151??

Have a great day,

Rob.

Single carb is an AQ 125 .Depends on the year of the boat.Jerry

It's got duals...

Re: Identify this Volvo motor!

AQ170 is a 6 cylinder, this one is a 4 cylinder.

Might be one of these, it has dual downdraft carbs...

AQ125B dual downdraft

AQ131A dual downdraft

AQ145B dual downdraft

Re: Identify this Volvo motor!

Instead of guessing, why don't you just locate the metal tag attached to the block around the distributor and fuel pump area. It's probably painted red along with the engine, but there is one there, and it tells you the model and serial number of the engine.
The drive is easy, read the blue tag on the back.

Re: Identify this Volvo motor!

Bubba, trust me, the AQ170 is a 6 cylinder OHV engine. The AQ171 is a 4 cyl DOHC engine.

Re: Identify this Volvo motor!

hi i'm gonna say aq 125 i have an aq 140 and thats not it go to volvo.com and to motor descriptions and look at the pic's you will be able to indentify your engine perfectly it will give you every thing you need to know about that engine and stern drive and yes its a 280 stern drive unit

Re: Identify this Volvo motor!

I cant be totally sure as you didnt include a pic taken from the engines starboard side and I cant see if theres an oil cooler or not but from the photos you posted it looks absolutely identical to the one I have in my boat...... and mine is the Volvo Penta AQ125A

I had not noticed the fuel filter. I'll pick one up and swap it out.

I also see that clear plastic hose not hooked up to anything. I believe that should go the bottom of the spark arrestor, you can check your manual to see the exact location.

Your referring to the hose in the last picture just to the right of the alternator by the oil dipstick?!?

From what I am told from the previous owner, this is a 125hp motor. Maybe this might help?

I'm a newbie to inboard motors. In the past, I've only owned outboards, so I have a few questions in relation to this motor/outdrive. On the top of the motor, that's where the coolant goes?!? I was under the impression that most motors used water sucked through the outdrive. Would this be a closed loop system that does not intake water from whatever the boat is in? I didn't really notice a place to put muffs on the outdrive, could this be why? Is there a way to flush that out? I'd like to as a precaution.

Thanks all for your help!

Re: Identify this Volvo motor!

I think Volvo has a wrong number there. If you go to your link and under engine type, just type in AQ170. It will list all the 170's. Don't you think it a bit odd that the A,B,C, and R models are all 6 cylinder and the D is a 4 cylinder? Also, there is no parts listing or manuals or anything for a 170D

Re: Identify this Volvo motor!

I'll check the panel tonight now that I know where it is and let everyone know. Anyone have a thought/idea on my coolant system?

 

[bomar76]

Re: Identify this Volvo motor!

Yep...it's a closed system and it says not to step on it....

Re: Identify this Volvo motor!

The engine coolant is a closed system, and circulates thru an inner chamber in the heat exchanger (the square box with the radiator type cap). Raw water from the lake/sea/ocean is circulated in the heat exchanger around that inner chamber and, well, exchanges heat from the inner chamber to the raw water in the outer chamber. The raw water then exits thru the exhaust.

The raw water intake is a series of slots on the front of the lower drive just above the skeg and "torpedo". It takes a different style of flusher attachment to mate up good with those slots. There is also a drain hole at the front of the torpedo that should be plugged when running on the muffs/flusher as that is a source of air that can break the suction.

Re: Identify this Volvo motor!

Check for engine number/type on or below the valve cover...mine is marked AQ125A right around there if I remember right. Yours is a 4 cyl. engine but with two carbs where mine is only one carb.

So then to start things off, I do NOT need to fill this up with water whereas it will fill automaticaly when put in the water and started, or is it a good idea to put some water in the heat exchanger to begin with?

Re: Identify this Volvo motor!

The engine side should be filled witha 50/50 antifreeze - water solution, the raw water side is taken care of by the impeller

Re: Identify this Volvo motor!

The inner chamber is up to you to fill as Bomar said. There is also a sea water strainer that needs to be maintained as well. You should get an operator's manual and read it all 2 or three times while familiarizing yourself with all the physical components rather than posting questions here then taking the answers too literally or the wrong way.
