I replaced the thermostat in my 1970 Evinrude Fisherman 6 hp. The first video I put out I did not install the gasket right so this is #2.

[@skyfly51]

The gasket is exactly what I needed to see

[@OmFishing]

Great happy the video helped.

[@benscratchin8014]

Thanks for the video. I just purchased a 1965 Johnson 6hp, that is very similar to the Evinrude model. I will be replacing several maintenance its on it, before I put it on my boat. Thanks for the info !

[@OmFishing]

Glad I could help. Keep me informed on your progress. Stay Safe.

[@benscratchin8014]

@@OmFishing - I got the engine to start and fast idle, but it was not putting out water through the exhaust, so I shut it off and ordered a new impeller, gasket, and driveshaft seal. The thermostat was okay but. I put a new one it anyway. I changed the gearcase oil (no water in the oil) I'm waiting on gaskets so I can put the new impeller and lower unit back together. If it doesn't run well, then I'll rebuild the carburetor.

[@williamgwiazdowski7370]

You make excellent videos. I'm a marine technician certified in Evinrude and Mercury and I also collect old outboards

[@OmFishing]

My only certification is the love of bringing these old outboards back to life. So please feel free to point me in the the right direction. Sometimes you read the manual and think you understand, But nothing beats year of experience.

[@OmFishing]

Thank you and stay safe.

[@christopherkarper1047]

william gwiazdowski question for you. I have a evinrude and I am wondering why it’s overheating. If I have it in a barrel it doesn’t over heat. But if I have it on the boat in the water it over heats in 5 to 10 minutes. What could be the problem? If it can be more then one thing please give me the list so I can fix it right. Thank you.

[@GringoSF]

very good spectacular boss video

[@OmFishing]

Happy to help keep watching and stay safe.

[@markboyd-graham2697]

Maybe the ground the advance plate to advance the spark more before the throttle came on. Yes it’s hard to imagine it would wear that much

[@OmFishing]

I think you are right. Somebody ground the plate. Thanks for watching and commenting.

[@wesw281]

What part of the country are you in. Looks beautiful around you

[@williamboydfoto]

I ran through some really dirty water (Louisiana bayou) and my 1965 Fisherman 6HP stopped spitting water from the rear exhaust. I replaced the thermostat and the impeller, but still no exhaust water. Do you recommend adding a telltale?

[@OmFishing]

Sorry to hear that, when I get sand in mine I take the thermostat out and try to flush the engine. Some of these engines have small water passages in side. It don't take much to stop it up. Did you try to flush water from a hose up the water tub when you had it a part?

[@yumagawlers]

Should you see water immediately upon starting the motor or only after the thermostat opens?

[@OmFishing]

You want to see the water come out with in a few seconds. If I don't see water in 15 to 20 seconds I shut it off.

[@thecrooner4jc]

Thanks for your help. I have this same Evinrude 6 motor and your videos helped a lot. I've replaced the thermostat and installed a new water pump kit, but the water is still not pumping out the tell-tale. I'm stumped .. any ideas now?

[@OmFishing]

My first question to you would be are you sure the water pump is pumping. I will sometimes force water up the lower unit with ear muffs or drop the lower unit and run water up the tube below the engine. Are the rubber grommet where the water tube connects under the engine in good condition. Did you take the hose off the tell tale and make sure it is clean. Does the water come out the tell tale if the thermostat let out. Let me know. Thanks for watching.

[@thecrooner4jc]

@@OmFishing thanks so much for the advice. I'll let you know how it turns out.

[@thecrooner4jc]

@@OmFishing .. it turns out the original impeller housing was shot (the driveshaft hole was worn) .. and the thermostat was froze up. I installed new thermostat and an impeller kit, forced water up the lower unit tube, and I'm back in business. Thanks my friend :)

[@antoniosidoni5310]

Hi OM FISHING, would you please explain what problem /damage could occurs to the engine if you use having removed the termosthat? Being it a bit cooler should not be a huge disaster. Am i wrong? Tks in advance for your replay.

[@OmFishing]

Proper engine temperature is critical for good operation. When your engine is running to cool the following conditions will occur, fouled spark plugs, poor idle operation, loss of wide open power, excessive fuel consumption, excessive carbon deposits in the combustion chamber. your engine will just keep building up with carbon until it stops. This will take soon time, but this is why it should be at operating temp.

[@antoniosidoni5310]

Mr. OM FISHING, tks a lot for your prompt and professional answer. Antonio from Rome (Italy)

[@arielcampanioni4162]

Good info I have a 1974 evinrude replace my empeller and I dont see water coming out but I never change the thermostat dont know if the thermostat is the problem any suggestions thank you for the help

[@OmFishing]

If you don't see any water coming out I would make sure the hose from the engine is clear and the exit is open. If that is not it I would take the lower unit back off and check that the water tube grommet for proper placement. I would make sure the impeller and pin are correct. Hope this helped!

[@arielcampanioni4162]

@@OmFishing thank you

[@benkanobe7500]

I have a question: My motor is an Evinrude "1966 5 HP "Angler" 5603C Long Shaft". I have the Factory Parts Manual, and Work Shop Manual. My parts manual shows the screw for the Thermostat Housing, the Cap for the Thermostat Housing, The Gasket for the Thermostat Housing, but no Thermostat. What the heck?? Was it not supposed to have one (seems very unlikely)?

[@OmFishing]

I looked in my stuff and I see the same thing as you. All the parts are there for a thermostat but does not show on for that engine.

[@josepabon1214]

Hopefully you respond back I could really use your help I have the same evinrude but my flywheel is locked up like when I try to pull the pull start the flywheel will not move

[@OmFishing]

I don't know if you noticed, On my motor the Starter lockout cable assembly is missing. What this does is stop the motor from starting in gear. It has to be in neutral. I never replaced that cable and brake assembly. If your motor will not turn check the lockout plunger to make sure it is releasing when in neutral. Hope this helps and stay safe!!

[@blueback21]

Awesome! Do you think a faulty thermostat would cause bogging down issues on a 68 6 hp Johnson. I rebuilt the carb so I’m kind of stuck now trying to figure out what the issue is. Thanks again

[@OmFishing]

I think the thermostat could make the motor go into safe mode and the motor would slow down. Just bogging could be a fuel issue or timing. First guess would be a fuel line sucking air at a connection. Be sure and let me know what you find.

[@blueback21]

@@OmFishing Thanks OM Ill try that fuel issue first

[@AlejandroBartomioli]

Hola amigo me podrías decir en qué tienda compras los repuestos del evirude 9.9 gracias 🙏

[@OmFishing]

Compro todas las piezas OEM. Compraré en Amazon cuando pueda encontrar las piezas allí. También compraré algunos en boat.net. Diré que la red para botes tarda mucho en entregarle las piezas. He pagado por una entrega rápida y no ayuda.

[@semajekrad6922]

I have one of these it hasn't seen much service I'm missing the proper and I have to do he thermostat but parts are hard to comeby here in the UK for such old motors Also the starter dog/ pinion gear has worn and dose not engage with the flywheel. Nevertheless it runs nicely when it's sparked up. If you got any 2nd hand parts for sale propeller, starter dog I would be interested.

[@OmFishing]

I will keep you in mind if I run across some. Send me a email. [e-mail]

[@Justin-tp3lr]

Not sure if they ship overseas but they have a lot of parts for these old evenrudes www.marineengine.com

[@peteryeung111]

$30+ for a thermostat asy is a lot of money, can i clean the old one if possible? Thanks

[@OmFishing]

Yes I have cleaned them and then put them in water and heated the water to see if the thermostat opens and close with water temp.

[@peteryeung111]

Thank you very much for the reply, I'll do that and test with boiling water. Cheers!

[@antoniosidoni5310]

Hi OM fishing, Would you please explain what happens to the engine if i use it without the thermostat? For sure it is much better to install a new one, but if, for any reason, i remove it is it very dangerous for the motor? Tks in advance.

[@shawnchannell984]

I would love to be able to ship you my motor to work on

[@OmFishing]

What problem are you having with it? I will be happy to help if I can.

[@shawnchannell984]

Om Fishing well it’s running now but still not pumping any water out. Had it running for about a minute or two, kept my hand on the side of the head to make sure it didn’t get to hot. I’m planning on retracing my steps when I rebuilt the water pump.

[@OmFishing]

@@shawnchannell984 if it were me I would pull the lower unit back off and find something to turn the shaft and put the lower unit in water and see it the impeller pumps. That way you know if the problem is with the pump or in the engine.

[@shawnchannell984]

Om Fishing it seems that the locking key had slipped out of place and the impeller wasn’t spinning. Rebuilt it again today and flushed out the cooling system by squirting the garden hose up the copper tube to make sure it had water flow all the way thru and out the “pee tube”. Success!!!! Thank you for making these videos. Huge thumbs up always!!

Wondering why my 1971 6 hp johnson.. Decided to only have a top speed of 6 mph.. Pushing a 1965 smoker craft aluminum v.. Any direction you could point me in.. I noticed the rich or lean does nada ... Ran in both directions of knob no difference in sound ... Please help

[@OmFishing]

First I would clean the carburetor. Rebuild would be better. but until we find the problem clean would be a good start. Then make sure the linkage is set in the proper place. Proper air fuel mix is very important.
