I have recently got a fuel pump kit for my 1971 18hp Evinrude. Problem is, everytime i put it back together and on the engine, fuel squirts out of two little holes in the fuel pump. I dont think im putting all back together correctly and i cant seem to find an in depth diagram to show exactly...
I am replacing the exhaust gaskets and head gaskets on my 1971 18hp Evinrude. I need to know what the torque specs are for the head bolts and exhaust cover bolts. Also the specs for the lower unit-gear housing. Thanks.
I have a 1971 18hp Evinrude that is a little rough. It has problems with overheating and it has a new water pump and the t-stat is fine. That leads me to believe there is something restricting the water flow. The old impeller was real torn up and a lot of the rubber was missing. I was told i...
Re: 1971 18HP Evinrude HELP!!
The reason i said the t-stat was ok is because i took it off the engine and it still overheated, so i ruled that out. The water pump was rebuilt with new impeller and case and cover. The old impeller was very chewed up so i thought i may have a piece of it...
My 18hp Evinrude is not cooling correctly. It lets some water through and the water pump is new but it is still not cooling like it should. I really need a diagram of the cooling system as far as where the water goes through the engine so i can check for blockage. It does fine at low speeds but...
I have a 1971 18hp Evinrude. I disassembled my lower unit to see why it was popping out of gear and discovered there was some water mixed with the oil. I applied some gasket maker when i put it back together. I checked the clutch dog and forward gear and they both look fine althought there is...
I have a 1971 18 hp Evinrude that i just replaced the water pump on. It is getting water through it but it is not a solid stream. After running wide open for a couple minutes it slowed down and eventually died. I touched the head and it was hot to the touch. When i run it slower than wide open...
Re: Impeller replacement on a 1963 Johnson 18 horse?
I was recently in your situation. I have a 1971 18 hp Evinrude. Youll have to take the lower unit completely off there is one bolt on the top and four on the underside. After that youll have to take out two screws that hold a plate on the...
I have a 1971 18 hp Evinrude that was not spittin up any water. I took the lower unit off and the impeller housing and got down to the impeller. It looks pretty chewed up. My question is what do i need to fix it? Should i just get a new impeller or a rebuild kit? Also, once i put a new one in...
I have a 1971 18 hp evinrude that i have installed a stop switch on. I took the two wires coming from under the armature plate and hooked them up to a standard toggle switch. When the switch is on, i get fire from bothe plugs but the engine will not start. When i turn the switch off i get fire...
I have a 1971 18 hp evinrude that i need a tiller handle for. It did have a cable steering system and a dual lever control box. I broke the throttle lever and i also dont like the cables running down the boat sides. My question is will a different year model and hp model fit my motor? I can get...
I have a 1971 rude that i just got running and found out that it is not spitting any water out. I started it in a barrel and ran fine but no water coming out. It has the hole right under the motor but nothing comes out. There is another hole right above the prop and it is putting out something...
I have a 1971 18hp Evinrude. I took apart the carb last night and cleaned it and am now wondering how many turns the needle should be in the carb. I took the boat out a week ago and it would not start. Could the needle adjustment be why? It has fresh gas and good spark. Good compression. Thanks...
I broke the piece of plastic of my dual lever throttle control box from a 1971 18HP Evinrude. I was wondering if anyone knows of a rebuild kit or something of the sort for this. the controls and cables are good just a piece inside of the throttle is broken. Or if anyone has the whole control box...
This is probably a dumb question but i was wondering if my 1971 18HP Evinrude outboard will charge the battery while it is hooked to the motor. (it is electric start) In other words, do boat motors have alternators to keep the battery from dying?
