Twin 140's on eBay

[Blue_Runner]

Have ya'll seen this one:

I guess that answers the question on performance for the twin 140's - 68 mph!?!? Sounds like suicide to me.

Still haven't checked the compression on my twin 140's yet. I did have one running but she didn't water only dribbled out of the tell tell. I only ran it for about 7 seconds for fear of burning the impeller. The motor cranked right up.

Soooo I took a wire and did some poking around. I got some junk out of the hose. Then I dropped the lower unit, replaced the impeller (impeller looked ok). While lower unit was off I tried to force water up through the intake to see if I could get water to come out of the tell tell - it did not. I still have the lower unit off.

Any suggestions?

Thanks,
Blue Runner

here we have my 21 foot welcraft v20


??????????????????????????????????????????
Which it it a 21 or a 20

68 mpg!! That boat was never ment to go that fast!! and unless it was a flat day and I mean a flat day I would not try it!!

$5,000 thats a great deal if the boat is sound. You could sell the motors and put a single 150 or 175 and make out pretty good.

I bet there is going to be a lot of cheap stuff coming out of Florida soon!!

:o Holy G Forces Batman!!!!!!!!!!!!!!
That's why the windshield is loose. ;D
I had trouble years ago with a motor I bought that the water tube was clogged with sand. The mechanic I took it to had a hose rigged with clamps to the lower pickup tube and applied water for a while until it cleared itself. I don't think he gave it a lot of pressure, but he said that once a litlle bit of water trickled through, it really started clearing itself.
I don't know what else to suggest.

I don't really know what to do either. Maybe I just didn't run it long enough?? Shouldn't it start pumping water out the tell tell within say 10 seconds or so?

Thermostats wouldn't cause this problem would it?

Only thing I know to do is just as you said - I'll take a zip tie and strap my garden hose to it.

Thanks,

I had a mercury that always pluged the hole!! I just disconected it from under the cowling and it pumed like crazy!! So i drilled a little bigger hole and left the hose sticking out all the time, Never had a problem again.

Ok, I saw something on OutboardRepairs.com that sounds interesting. The guy asks how the pump should work with his 1990 loop charged 120hp Evinrude. Here is what he says:

"When you first start your motor is it normal for the water pump to have to "prime up"? My tell tale doesnt flow until about 30-40 seconds after I crank it up."

Then some smart guy answers:

"It may take a short while for the tell tale to operate on a looper. The water cavity is very large and takes a few seconds to fill. Your water pressure gage should start working almost right after the motor starts since it is T'd into the supply. "

But here's the thing - the little "T" he mentions - well my motors aren't hooked up and I can see where the previous owner cut the hose off the bottom of the "T" which evidently is where the gauges are connected.

I'm thinking I should do this:

1) Plug the gauge part of the "T" off for now.
2) Put the lower unit back on.
3) Crank her up and let her run at least a minute on the muffs.

By George some water should come out, don't you think? I'll post back and let you know.

I purchased my V20 this spring with a Force 150 on it. *I had a similar problem with no water flow. *I ended up changing the water pump but I learned some things along the way. *1- Thermostats do not open immediately mine opens after about one minute. *Try removing the t stat and running it without one. *You should have immedate flow, after *determining if that is the problem replace the t stat. 2 Make sure the flow tube is in it's proper position. *3 Somewhere on our engine there should be a plug to the water jacket. Remove this plug. You should get flow and by the amount of flow you should be able to tell if your pee tube is blocked. *iboats.com is a good web site to ask questions about your motor. *Good Luck Bill Mc

Can you backflush it?

On my yamaha, when I disconnect the pee hose from the nipple on the lower cowling, the diameter of the pee hose is about 1/4 inch. On my garden hose, I have a multi-function nozzle. The pee hose fits over the sharp stream nipple on the garden hose nozzle. I can hold the peehose over the nipple and backflush the cooling passages.

The thermostat should have no effect on the telltale.

My motor does not pee on startup at the lowest idle speed. Raise the idle and it pees.

You won't damage the impeller in seven seconds if it is wet and otherwise sound. Running dry is what does them in.

Hope this helps.

I was able to force water through and a little bit of stuff came out. I have no doubt it will pee now. The new problem of the hour is not being able to get the lower unit back on! I've done this a couple of times before and never had this much of a problem.
