**Update**Advice needed Re: Volvo AQ145a & 280 leg

[neilmw]

I have just aquired a new project, very tatty boat that came free with lots of water inside..... what I need to know is where to start with the engine, both the engine & drive are a unknown quantity at the moment and I wouldnt be suprised if they are a throw away job, however, the boat was aquired legaly by the marina 2 years ago as the owner done a bunk owing £4500 mooring fees, I know the engine has not been started for 5 yrs but was known to be running fine beforehand. the sump has been submersed, and also the starter (partially) in rainwater. Would be obliged if someone could give me some idea of where to start with regard to initial checks, pouring slimey stuff down the potts etc etc.<br />Regards<br />Neil

Neil,<br />Find a Seloc manual soon.<br />Check for oil contamination in the oil pan, see if you can turn the motor over by hand through a couple of turns. Use the front crank bolt to turn it with. <br />Pull the spark plugs and squirt some engine oil down the holes. Not much required 4 or 5 pumps of an oil can may be enough.<br />If it turns over ok then drain the oil and refill with fresh oil. Lift the valve cover off the engine and refill the oil by pouring it over all the valve gear.<br />Remove the starter and have it checked out if you suspect it has water inside it.<br />After this point you can check out the rest of the electrical and fuel systems (drain and clean out carby)and if all looks well see if you can possibly try to start it.<br />Make sure that the outdrive is in some water at this point as you will need to have some coolant flow. Dont panic too much about the raw water pump until you can get the engine runing.<br />The raw water pump will need to be overhauled anyway as the impellor and seals will probably be US by now but you can still try to start up your engine at this point. <br /><br />Good luck,<br /><br />Peter

Cheers Peter, thats a great help. I have only recently got to grips with the workings of the mercs, now i have to start all over again..........is it possible to run these out of the water with flushing muffs like i do with the mercruiser?

Yep, no problem. Leave the leg in the down position, connect the muffs - you're good to go. Don't raise the RPM's much past idle though, keep it under 1000. I usually remove the prop - it's safer and you can check for fishing line at the same time.<br /><br />Aldo

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

Thanks Thats very usefull, I assume the engine is a aq145 as there is a parts sheet with the documents, but is there any way of identifing the engine by way of an engine number and where i might find it?<br />Regards

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

Hi there <br />If it hasnt been tampered with there could be a plate on the side of the engine with the engine model and s/no as well as the stern leg model # stamped on it.<br /><br />You also need to plug the bottom water inlet hole on the leg or you will suck air when using the muffs. <br /><br />Good luck<br /><br />Peter

Gosh Neil, you seem to be a magnet for troublesome engines. First a 470 style Merc, now a Volvo rubber band (Timing Belt) engine. <br /><br />Here is some info on your engine. AQ-145A

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

Neil, you havent mentioned whether the motor will turn over by hand?

Cheers don, yea glutton for punishment....think i'll start sailing!<br />the link you posted says "You are not authorized to view this page".<br />I have yet to try and crank the engine yet, put a few squirts of oil in the pots today, thought i would leave it overnight and try tomorrow.<br />Will let you know, unless of courese i break my arm trying to turn it over, in which case see you in six weeks.......

Not sure why the link says that, it's just a .pdf file showing the product bulletin for the engine.<br /><br /> http://www.volvo.com/NR/rdonlyres/F073D4BC-E1F9-4A4F-9A88-59591FD9CC9E/0/AQ145A_280D_1979_en.pdf

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

Curiousity got me looking at the PDF, I noticed the gas recomendation says 90 octane. I don't know about Europe, but not too many fuel docks in the US carry it. Just a comment...

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

It's also a 1979 product bulletin. Lots changed since then.

Neil<br />If you can't open it from the links given, emailing isn't going to help. You have the security settings on your computer setup to prevent that type file from opening. Even with an email it would either prevent it from being opened or not allow it to download.<br />Check your security settings or any blocking/firewall/or ad type software settings.

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

Right again don, disabled firewall and got it.<br /><br />Ok, had anaother look at this engine yesterday, put a spanner on the front crank and could not budge it.... the plugs have been left out and i pumped approx a pint of water from the sump prior to the sludge coming out, Think the boat could do with a slightly bigger engine as well, so will be looking round for something else to fit, however does any body know what engines will mate with the 280 leg and bell housing? I was thinking of a aq171.....what do you think?

 

[neilmw]

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

Any idea?

 

[Don S]

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

With that engine, you will need another Volvo engine to fit the bellhousing.<br />Changing to possibly a V8 or V6 is going to require a different gear ratio, and trying to find an exhaust Y to fit the bellhousing.<br />Best to start looking for another engine if that one is locked up.

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

Cheers, any idea which engines will fit the 280 and bell housing? I was thinking of a aq171?

 

[Don S]

Re: **Update**Advice needed Re: Volvo AQ145a & 280 leg

The 171 has the same gear ratio in the drive, but it's a 6 cylinder engine, do you have room for it?<br />I also have no idea if the exhaust will line up or not or if the bellhousing will fit.
