cann't find spec's on gamefisher man ?

[sam111]

I have an old engine that runs and has been over heating.
It is a sears gamefisherman 7.5 model number 217 566754 serial number 780 10949

Question
Does anybody have a clue if this engine is air cooled or water cooled. I believe now that I have been taking it a part I don't see an impellor/water pump or thermostat but I do see radiator fins so I am assuming it is overheating because of being dirty or because the cover is cracked and letting air escape before the fins are cooled...
Can anybody with more experiences tell me definitely if it is air cooled or water . And if its air cooled correct me if I am wrong but the only thing it could be is cleaning and making sure the cover circulates the air properly. That should fix any cooling issues correct... or is there more issues to fix an air coolant system that I am over looking?

Question 2
I called sears and they said they didn't have parts for my model or it didn't come up as existing on there site.
The model/serial is given in the sticker in the inside of the engine after you take off the cover. Does anybody know the year of this model or weather I can get an old manual for it. Something in pdf... This engine is pretty light weight and simple to take apart for 95% of the components I would imagine any general manua similar to this model number/year gamefisher would do.

Thanks for any help I will post a picture soon

Re: cann't find spec's on gamefisher man ?

its air cooled with the exhaust housing being water cooled. water is pushed up the exhaust hosing to a water pump which pumps it to the base of the power head and then it comes out the exhaust. never seen one over heat. I have the manual for it if you would like a copy in PDF. email me and I will send it to you.

Can anybody tell me where I can get the tools for the above.
I need to know the exact tools for each of these ,one for putting on those clamps on gas lines or rubber pipes in the picture posted.... the other for pulling of the magneto/flywheel.

Thanks for any help with this.
I would imagine an auto parts store might have these but would like to know where I can get the most bang for my buck...
i.e the most widely used/works on most of all small engines , as well as fairly cheap and good quality to last long.

Other then those 2 need tools and maybe a carburetor adjustment tool/something with the carb... It seems that I will have all the tools needed to totally disassembly/reassembly this engine. I don't have to touch the pistons,piston rings , crankshaft , valves because compression is not a problem. All the rest of the systems I am cleaning and repairing i.e fuel /exhaust , ignition , starting/charging , steering ,cooling and lubrication systems. (which in my case these systems are pretty primitive which is good since I am first starting out with small engines repairing )

Just use any three hole puller, maybe a cheap harmonic balancer puller to pull the flywheel.
I just use a regular pair of plyers for the hose clamps.

So does all three hole pullers work on all the types of 3 hole flywheels .. or will I need a certain kind.

As for the hose clamps they are easy to slide down the rubber pipe with pliers but will plyers work to install new clamps on pipes easy or is it going to be a ***** to get on... I know I am going to have to be working on tight spaces of tubeing so is plyers enough or do they have a special tool for this

Re: cann't find spec's on gamefisher man ?

Sears is telling you they can't find parts for you because the number you gave them is bogus. Look more closely at the number, and enter it here;

Do a model search. You need a new pump impeller, and that will require you to remove the lower unit. You will need a fuel pump element, float bowl o-ring, needle and seat for the carburetor. After you have been to the Sears site and got your part numbers, call these people to order parts;

Re: cann't find spec's on gamefisher man ?

Your not making sinces this engine is air cooled so there is no water impellor that I see why would there be there is no water needed to pump. You maybe getting confused with oil pump but for this 2 cycle small old engine I don't even think it need one... since the crankshaft spinning provides the oil/gas mixture to cycle around for lubricating. So I don't believe there is any real pumps need to be replaced or actual in this engine.

As for the model the sticker says 217 566754 the only thing I can say is maybe this is a model number for something else for this engine that I am missing where to read the actual model number. Don't know I will look closer tomorrow.

I think my overheating problem is contributing to one of the following (that I am going to trouble shoot out)
1)fuel mixture to lean
2) incorrect oil-mixture ratio
3) cracked cover or dirty/bent air cooling fins not allowing the air to cool properly (i.e dissipate the heat properly at the correct rate)

most likely a combination of all three.

for water cooled I would also have to trouble shoot these but they are not applicable
1) faulty thermostat
2) restricted water inlet
3) water pump/impellor not working
4) sand or silt build up
5) leaking or cracks in water systems tubes or cases
6) boat sits to high on transom so the water inlet is not in water

whats sad is nobody reads their replies from people who are trying to help.

Re: cann't find spec's on gamefisher man ?

sam I need your email address to send you the manual. I also dont understand how thats a bogus model number. I think its a 1986 the last year eska built sears boat motors.

Re: cann't find spec's on gamefisher man ?

Also I am wondering if I wanted to replace the carburetor how much would this approximately cost for this engine.
I would imagine the sears gamefisher engine is more just a Tecumseh like engine so it should cost equivalent to one of those models. Though I am new at this and don't know even what a fair or average prices is if I have to replace it. And it still seems the model number is not existent though maybe when I take more parts off I will see the number on the side of the engine block.

I already check the ignition system wires , and spark plugs I see the blue so spark plug is good , I see the test light orange so current is getting all the way to the spark plugs the only problem I see with the iginition system is it doesn't always have a strong current or blue spark have to spin it a lot to duplicate. So I am thinking when I get ignition/contact cleaner and clean the ignition it should resolve the issue I am hopeing. If not then I may have to buy a CD unit or other pieces of the iginition system.

The coolant system I am pretty sure I can resolve with not much money spent if at all.
Ignition system I am hopeng just cleaning.
fuel system I may have to replace the carburetor ( since it leaks some time when to much gas is squeezed out of the fuel tank hand pump.
exhaust system I think all it is is sending the exhaust gas into the water out the hole above the propeller (I am not sure if this was not submerged in the water if it would cause an overheating issue because I believe it sits to high on the transom of this boat to be submerged without boat modification.) But if it doesn't need to be submerged then cleaning/checking for clogs should be it for this engine.

Re: cann't find spec's on gamefisher man ?

As brim_buster said ::
The powerhead is air cooled.The leg is water cooled, there is an impeller to pump the water up to top and it produces
a mist out the relief holes on the leg.
Without cooling it will get very hot eventually damaging the motor.
The impeller is very often shot.
You do need to be sure the intake is clear.
The carb has a fuel pomp bladder in the intake flange.
It can be used with a remote tank or the on board tank.

Re: cann't find spec's on gamefisher man ?

ok so autozone near me didn't have a puller tool for this engine that works. I rented a harmonic and a steering wheel puller but that didn't do any good. To large didn't fit right to pull. I am wondering where I can get a puller to take off the magneto/flywheel on most small engines and outboard motors. Is there a general puller that gets most/all of small engine lawn mower , tillers , chainsaws ,..etc and most outboard engines that you guys would recommend. I am stuck until I can get this flywheel off the engine.

Also was kind of curious on where you guys get your tools from is it an autozone , napa , homedepot , sears , ACE or directly from the manufacture ?

How To Remove A Flywheel Safely Without A Flywheel Puller - YouTube

Re: cann't find spec's on gamefisher man ?

I bought a cheap universal puller at harbor freight.
It is indeed cheap and you may have to replace the bolts with a higher grade.
I've done about 1/2 a dozen small outboards with mine.
I've also popped small flywheels with 2 big screwdrivers and a hammer.

 

[MahtyMaht]

Re: cann't find spec's on gamefisher man ?

That fly wheel has a three hole circle of about a 2" diameter around the crank, but there are no threads in those holes. You'll have to tap threads in them with a 1/4 - 20 bottoming tap. The holes are a bout .200" diameter, so they don't need a tap drill. The aluminum is really soft like pot metal. Fill each hole with oil, then tap it - oil flowing out of the hole helps carry chips from tapping out. Again, you obviously have no problems under the flywheel, you need a pump impeller.

Re: cann't find spec's on gamefisher man ?

I got the flywheel off using a nut on the end a hammer and a large thick book.
My other question so far is totally unrelated to the flywheel disassembly it is this
... when removing the lower unit to check / clean the impellor I am wondering if there exist a thermostat for this engine or if it is just pumping water thru the lower cases and out the exhaust pipe above. If not then temperature regulations of how cool it is getting not an issue. Just can't find the thermostat does it exist in this gamefisher man engine that is air cooled with lower unit water cooled ?

 

[sam111]

Re: cann't find spec's on gamefisher man ?

Thanks I got the spec's that you sent me perfect I also noticed when I opened up the water pump cases on the lower unit the fins of the water pump are all broken when I move the shaft it rotates also check for clogs and am going to clean it /oil it as well.
But the problem looks as it is just replacing part 26251 impellor which the label is also on the impellor itself so I know the manual is pretty accurate for the exact parts. My only problem is since this engine is very old like in the 1976 ish era is it possible to still order an impellor equivalent to that part number that will work in my old boat engine?

Where do you typically order thru would it be sears , an online store , right from the engine manufacturer , or a marine ???
Because with this manual I am at the point where I can just right down the part numbers I need and fix this thing completely provided I the price is not ridiculous.

Also there is a few part I don't understand the point of on page 20 of Gamefisher75lowres it is part 4 in picture and it looks like a metal push button with a rubber wrinkled tubing around it ... it is in back of the impellor casing. I just was wondering what the purpose of that is.
Seems to me it is not a thermostat because when I hold it up or down the water that I pour still runs into the impellor cases. I also check the tubes and they are not clogged so it is just the impellor I need also maybe a good idea to replace the washers.

The only other question currently that I am coming towards is removing of the magneto from the crankshaft I know the flywheel I took off only had one way to be placed on the crankshaft because it was 2 cycle and the crankshaft on these engines usually have a maker that makes it impossible to install incorrectly. But as for the magneto part that has to give a spark to the spark plug when the piston is top dead center for max combustion efficiency can you put this back on incorrectly or do they make it so it can go on only one way?

Similar question is if I took out the piston/connecting rod assembly from the crankshaft is there a wrong way to install it on the crankshaft which would make the spark fire not when the piston is top dead center. Those questions are what I am worried about i.e connecting rod , crankshaft , and magneto reinstalling so that spark lines up with top dead center for piston. I already know I can't mess up flywheel on crankshaft but I am unsure about crankshaft/connecting rod , or crankshaft to magento spark fire.

Does anybody know if there a wrong way to install/put back on the connecting rod to the crankshaft?
Thanks for any help
I am also sure I am going to need a place to order these parts from that I need .

Re: cann't find spec's on gamefisher man ?

I would say if your going through all this trouble for a little air cooled motor, you could take that money and go buy something else. One that runs and needs little or no work and be happy and not spend all your time rebuilding and be fishing instead...LOL just saying.

Re: cann't find spec's on gamefisher man ?

Removing the flywheel that way can dislodge/damage the retaing ring below the lower crank bearing - your motor will not survive if that happens. If the engine runs at all, I cannot imagine why in the world you would want to take the crank out of it. There is no possible way to improve the motor by taking it down to the crank, none. Yes you can get an impeller. Take part numbers from the Sears site, and call these people;

They are the best place to get OEM stuff.

Water just flows thru the engine, no thermostsat.
