Re: Update

That "Scratching" sound is the antisiphon valve working, and exactly why you can't blow back into the tank. It's there to prevent a siphon starting if the hose fall off the pump and drops below the tank.

couple ounces of fuel down the carb throat will start it, but will only run for 2-3 seconds tops.

May be you have water in your tank and pumping water and not gas.
I would strongly suggest you get a water seperating fuel filter and install it between the tank and fuel pump, and determine if you are getting gas or water out of the tank.

Re: AQ125A 270 flushing question

You could take the hose off the fuel tank and put it in your portable fuel can. Try running it that way. If the carb is full of water, you may have to keep pouring and running. Be carefull! If the boat finally runs you will know your fuel pump is working and know you 've got water in gas.

if using the portable can doesn't work than it's probably the pump or clogged pickup in the tank.

Add that to your list. Not expensive.

Re: Update

Yeah probably will get a fuel water filter seperator deal.

Im leaning towards a plugged intake right now, it took a lot of suction to get the gas up that tube, but i am not gonna say for sure until i do the gas can test. It could very well be water, the carb doesnt smell gassy but than again i can still taste it as i write this.

Will this one work? http://cgi.ebay.com/ebaymotors/Mari...oriesQ5fGear] Marien Fuel Water Seperator kit

Or if i can get it cheap enough http://cgi.ebay.com/ebaymotors/Merc...oriesQ5fGear]Mercury I/O Fuel Water Seperator
Would be something id do in the spring time.

Re: AQ125A 270 flushing question

Ok, ran it off the portable gas tank.

Pumped throttle a few times and bang, she fired right up and was a bit cold blooded but she ran and finally leveled out she's always been tempermental at idle, even the original owner said it was untill it reaches 180 then will idle fine all trip long. I took a video of it running. It does need a tune but this gas is a couple months old. It does sound a little rough and bad in the video but i will say it has a more healthy deep rumble than the video.

Either of those fuel filter work, if i could save money id try to get the mercury one to save some $$

Also with the drive down the exhaust bellows still leaks warm water out it. Time for a new exhaust bellows i assume. And a tank flush and a new antisiphon valve, and a new hose this one was kinda cruddy.

Re: AQ125A 270 flushing question

Nice to hear its running.:)

I hope you have the water muffs on at all times.

I wouldn't worry about the exhaust bellows leaking a little. Its the ujoint bellows that is much more important. Some day we'll get to that....

Your engine shouldn't rumble at all. Its a four cylinder motor!!!

I'll bet, assuming the motor is solid, you could get it purring with a good tune up, including all the usual parts, proper timing and dwell adjustment and perhaps a valve adjustment.

Did you hook the fuel tank back up and try to run it on that again?

Don S:

I would take this to mean your antisiphon valve is ok. Listen and read what Don says carefully. He can say a lot in short responses and is normally dead on with his analysis.

You can get those fuel/water filters anywhere. I'd get one that you can easily get the replacement filters for.

All the leak does is drain the tank out. No biggie i guess. Of course i got it on the muffs, the side of my shed got a free shower from the drive.

Its an exhaust rumble i guess, another fellow at a dock had the same motor i did, his did the same said it was something to do with the exhaust on the drive or something. Cousin has a n AQ200 with a 280 drive and it is as quiet as a mouse.

Yeah gonna do a tune on it come spring time, the boat is quick gets up to 35mph easy according to my gps. Gonna do a tank flush as well, probably got some water in there. I'll come up with a fuel water seperator by then as well. As i told my dad there lots of maintence.

Did you hook the fuel tank back up and try to run it on that again?

Nope stopped after a few min of running in the gas can and had to get some stuff made up for thanksgiving. What oil evacuator do use to get the oil out? The one i had didnt cut it, its not a pressure one. I was looking at the liquivac topside.

Yeah, gonna look around some.

Not sure if you have many options. The older motors don't have the fancy user friendly dipstick tubes like the newer ones. Search Oil Change threads. There was one going recently with all kinds of techniques. I double up a couple of good garbage bags and drain the oil the old fashioned way.

Well okay...What am I supposed to do til then?;)

Yours will quiet down as well once you get it dialed in.

You too!

Re: AQ125A 270 flushing question

The boat is quiet when i run it in the lakes. The water muffles the exhaust obviously. Engine is pretty quiet except for an ocasional belt squel (on my list to replace)


Wish i could do my oil the old fashion way. My catch pan will fit under the pan between the transom and the bilge pump. I felt for a drain plug all i could feel was a huge nut i guess, not sure if its a nut or a cap i can twist off, felt pretty coroded or rusted (couldnt see) For all i know its something else afraid to take it off cause it doesnt leak oil, or burn it. Looks like northern tool carries the one im looking at, probably will get it and if it dont work, they have a good return policy.

I hate that dipstick tube on mine and whats said if they were to say put a strait one in, it would have plenty of room to check it, instead of routing it to the front of the engine.


Have a great day, and dont eat too much

That brought me back to high school!! I worked at Rapid oil change and I remember the Volvo's had huge drain plugs. I think its metric but I seem to remember using a 1 inch socket or wrench.

I'll take a peek at the plug on it using a mirror and see what shape its in. If it looks good then i will just drop the nut sounds easier than a vac pump. My luck typically goes: Work on something, have to replace something else, that costs more than what i replaced.

The gas tank kinda threw me off though wasnt expecting it to mess up, i think i have the owners manual for the tank. havent been out in the boat yet since wednesday. (Dont think i could get in with how much i ate lol) One thing i noticed is that the gas does slowly drain back down the hose into the tank. From what i read its not supposed to do that. Thats why it started squirting gas out the carb when i sucked it up. Not sure how powerful the pump is on the engine.

Ya, mine does too. I'm pretty sure it's a fuel pump problem. I'm changing mine next spring. My local Napa store can get me one pretty reasonable. You may want to look there. Its got to be the marine type with the tube going to the carb.

I'm not sure what to do with your gas tank. Don S usually say to buy the cheapest electic fuel pump, wire to the battery, pump the fuel out that way. This may not be necessary however depending on the age of the fuel.
If there is water in the tank, it would sit at the bottom as gas floats on water. there could be a small amount of water in the tank, but since your pickup is at the bottom you may be pumping mostly water, especially in your driveway where the boat isn't rocking around.

I'd be tempted to pull the line off at the carb, stick the end in a quart size jar and turn over the engine. You can pull the coil wire off to keep it from starting. If the pump is pumping, you should be able to fill that jar half way in 15-20 sec. Allow that to sit and see what you find in the jar.

Again, be carefull!

One other thought on the oil change. If you can get the drain pan under the drain plug, will you be able to remove it when its full of oil?

Best of Luck!!

I'll check it out, still probably gonna do a tank flush anyway, theres only a 1/4 tank in there, or so the guage says. I wanna do a sensor change on it anyway because the fuel guage bounce around too much even at a flat idle in the drive way. Feul did alright pumping out of my gas can into the carb but then again the fuel pump doesnt have the restriction like it did with the antisiphon, on the gas tank. A gas tank cleaning and new siphon valve is cheaper than a new pump. Hard to say tho.


My oil pan has a scew on lid where the oil drains into.


Can't wait for the fishing season to start again, wanting to get out into the bay this year and do some salmon fishing and crabbing, i know i have to get the boat properly ready for the winter so there is no problems come spring. Then after we go into the bay we always take the boat to a lake and run around and fish for a few hours. This does three things, cleans the painted axle on my trailer of saltwater and effectivly flushes the engine out, and if i get some more trout i have more crab bait. :)


Update: Looks like i just won a fuel/water seperator on e-bay.

Re: AQ125A 270 flushing question

Dude the bag trick is awesome way to go, easy as pie. Helped my cousin do his. Mine was being stubborn again today and not wanting to start. Plugs werent too wet, but very dark, so i am gonna break down and do a tune up now so i can get it started and change the oil. I can drain the oil now but i wanna warm it up first.


Thanks

Were they wet with fuel or water? Did you smell them?

Oh well, you'll just be that much further along in the spring.:)

Do you have or have access to a dwell meter/tach and timing light?

We'll be here to help!!

They were damp but not really gassy smelling so i think i am dealing with some water. But with the plugs being black and the cables stiff as a board im gonna change em, They maybe original or older wires they have german writing on them. They dont have a year on them.

Im contemplating switcing to electronic ignition, a petronix system is not too awefully expensive, around 100 give or take if i replace the coil.

I dont own those tools but i probably can rent them from my autoparts place. I never done timing on a engine before.

And what does stiff cables have to do with what the spark plugs look like.?

You need to find a qualified mechanic if for nothing more that determining what is actually wrong with your engine/drive/boat. You don't seem to really be up on what is good and what is bad.
I'm not trying to be an azz here. I't just a feeling I get reading your posts.
Get the major problems (water) found and cured quickly. The you have all winter to learn and tinker with your engine and drive. But don't let them get destroyed by water before you learn.

Thats not a bad price, I thought they cost more! I'm pretty sure you would need the matching coil however. It would save you the the money for the points and condensor and you could skip the dwell adjustment. You'd still need to adjust the timing with a light. Timing is pretty simple.

Only thing I can say is that most of the guys on this site seem to prefer points. I guess they're used to them. I don't think you would get any performance increase with the electronic ignition but I can see the temptation, 30 years ago it would be a good thing to learn but nowdays everythings electronic. When I got my boat I hadn't worked on a points type Dist. in a long time. Took a while before it came back to me.

Re: AQ125A 270 flushing question

Not looking for performance gain from the electronics, just simplicity. Im used to points my old rototiller has the points/condencer setup on it and use a feeler guage to set the gap, timing is done by lining up mark, the boat is slightly retarded cause its set for 90octan, which i run 89 cause 90 is no longer available. Its fun watching people who never used my tiller before, they describe it as fighting a bull by the horns. Its got a 6hp Tecumseh engine on it. Most the new big ones come with a 4hp. Did a carb overhaul on it last season actually had to tone down the govenor becuase it was so strong.

Alas when it comes to vehicle/boat engines and carbs im clueless.

Get any good black friday deals?

Ha, I had an old snow blower like that, Who Driven' Who? It was so much work steering it around I went back to shoveling.

Ya know, when in doubt, do what Don says. He sees the bigger picture when it comes to boat mechanics. Figure out your water or problem if you've got one. The boat ran on the aux fuel can before, is that what you tried last time? Pump some gas into a container like I mentioned previously and see what you get. If you do it methodically it will be much easier and if you do it the way Don says, he'll be more willing to help along the way, In my opinion.

Have you used this boat much on the water. How has it performed for you?

Was glad to see your outdrive fluid was okay.

You're kidding, right?

Sorry about my writing i tend to combine a lot together in one sentance. The plug wires are stiff, i never felt plug wires as stiff as those, if i bend them they dont straigten out. Plus the spark plug ends on the wires are a bit corroded or moldy on the inside.

The plugs are dark, there are two different brands installed on the engine 1 volvo brand for sure, and the others are NGK. While i may not be a mechanic i know most the easy basics, and what i can do and what needs to be taken into the shop.

Again sorry about me running everything together, i usually have to read my post 2-3 times to fix grammer errors, and seperate stuff
