Please explain this Flying Scott to me!

[flyingscott1962]

I am not getting good flow from my tell tale...sometimes it works well and sometimes nothing comes out. The question I have is what is the stream of water coming out from behind it? It comes from the hole in this pic that is just to the left of center. You can also see the tell tale on the tube to the left.
They seem to be proportional to the output, and the water that is coming out is hot. But the power head seems too hot to me.

 

[flyingscott1962]

Here is the stream coming out

 

[flyingscott]

You should not have water coming out of there it should be coming out of the exhaust relief. You could have a bad base gasket which you can still get new. Did you have the powerhead off for any reason, you will also want to take a look at the head make sure it's in good condition they like to warp. Have you checked the thermostat yet. Look up 1959 scott mcculloch 40 hp on you tube and watch where the water comes out.

 

[flyingscott1962]

I haven't taken the PH apart at all, honestly the one Bolt on thr thermostat cover broke when I took the handle off and I am afraid the rest will break off. Could that be caused by a stuck thermostat? Honestly I don't know what that stream comes from, it must be the water loop somewhere, a bypass or something?

 

[flyingscott]

You are going to break bolts off on that motor kind of the nature of the beast with that. I don't know why you have water coming out there probably the base gasket like I said. When it runs see where the water is coming from those are just drain holes.

If you think about selling it PM let me know your location I might be interested if you decide to go that way

I have an evinrude 30hp , 1956 vintage with a busted fillister head bolt that will result in a leak exactly like you have there - at some point in the future.
I'm just waiting for it to fail. Not worried about it in the least.

I have to think that the only thing getting damaged is losing a bit of curb appeal.
It may be that it is fine to run as is if your repair schedule does not have am opening anytime soon.
Best of luck.

 

[flyingscott]

It is not fine to run as is because you have no water coming out the exhaust relief. So you have no idea if the water is going through the block those heads warp rather easily when overheated. That is a 75 hp Mcculloch not a 30 hp evinrude. Take care of the cooling issues and enjoy a really good motor that turns heads.

I posted this video. Please let me know if you can make sense of it.

Was it you that painted the powerhead if so did you replace the base gasket. That is not right at all like I said https://www.youtube.com/watch?v=o1SS9sWOwXU watch this link. Don't mind it's only a 40 hp the principle is the same for the water flow. You either have a bad base gasket or water tube seal your motor uses compression fittings on the water tubes make sure they are all good
. Here are 2 places to get gaskets laings has a complete engine set. Vintage outboard has the head and base gasket for it you will have to make the water jacket gasket. Your powerhead is newer than your motor 64 or newer probably newer. All I can tell you is you have a leak somewhere you are not supposed to have. You have 2 videos up there the other one looks like correct waterflow then it looks like you lose it. I have never seen a peehole on them but stuff gets painted over all the time

I painted it a long time ago but I left the head and thermostat cover on it and took everything else off.
If the gaskets are bad there is no way I can devote the energy to fix them myself, and sadly it seems no (professional) mechanic will touch my motor.
It is probably a 62, since the flying scott boat and original trailer are all 62 and they are a matching set.
I wish I could get it all redone, I would pay to have the whole engine overhauled if I could but it seems unless the engine and their parts can be pulled up on a computer, boat shops won't touch them.

 

[flyingscott1962]

I see the video and the water was definatley coming out of that relief once upon a time but now it's just streaming out of that mysterious hole, it's not a drain from the base plate as there is no water in the motor enclosure.

 

[flyingscott]

Why can't you fix it yourself it is very easy to do. I would also do a compression test. When you took the distributor did you time it right. There is a sears manual on ebay covers those motors a very good manual. Go to the AOMCI website and look for someone in your area to work on it. If the guys at the antique outboard site can't help you no one can.

 

[flyingscott1962]

I did a compression test today and got 130, 121, 125 from the top down...those seem like decent numbers. I think I will try to remove the power head today but not sure where to begin, by removing the handle and all those Allen bolts on the bottom I suppose

 

[flyingscott]

Yes good compression it's fairly easy to do.

 

[flyingscott1962]

First I want to say thanks for the help and the encouragement. I dove into it and I must say, although I am no mechanic I can tell that it's not supposed to look like this. I suppose all that stream of water was just coming from a missing Allen screw. I imagine if I just replaced that my tell tale would have spit out fine. But I needed to get into here anyways. Please see pics.

Not a problem looks like you need a thermostat and a new crank seal. Also what seal is on the top of the driveshaft ,what screw was missing? I think the link for laings will be your best bet as the seals and gaskets are in the gasket set he sells. He will also have the thermostat for it.

 

[flyingscott1962]

The rear center Allen was missing. Funny how it taps into a water passage...
Would there be any value added if I removed the head? Are those bolts as fragile as the head cover plate? Should I replace the head gasket or just leave it as is?

 

[flyingscott]

If it was mine I would but that is up to you. The bolts on those motor always break so more will probably happen. When you put the bolts back into the motor use a sealer on them.

 

[flyingscott1962]

I ordered the gasket set and thermostat today. Does the set include the crankshaft seal also? It's hard to tell in the pics.
