Hi The cable was rotted. I made a new one and things are much better. Now I need to know how to configure the tach. Please see the back of the tach. I bought this tach a while ago and I have misplaced the instructions n And this is for a 3 cylinder motor. Any suggestion on the right...

Hi It is a 1977 75hp Evinrude 3 cylinder. So I can see about 12v at the control box. When I hooked up the accessory cable and checked the voltage at the cable ends I got zero volts. So I checked connectivity between the accessory cable ends and the 12v and ground points in the control box...

Good day, Could appreciate a bit of advice. Setting up a tack on my Evinrude 70773S motor. I’m using the Evinrude tach cable that connects into the control box. I thought things would be simple but as usual they are not. Wires from the cable are connected correctly to the tack and plugged...

Hi Found a mechanic who works on these old motors. A good chunk of his property is covered with old motors. Dropped it off and it was all done in two days. Dozed a few others things I didn’t know about and indicated a few things that still needed to be done which he thought I could do saving...

Thanks I will get a manual I have seen people fiddling with the bottom screw. What are they setting? Thanks Alex Sent from my iPhone using Tapatalk

Hi Would anyone know how to set the idle speed on a 75hp 1977 Evinrude? I believe it is a screw on the attached picture. Thanks a lot. Sent from my iPhone using Tapatalk

Ok got it. What about the style? Front roller and rear bunks? Alex Sent from my iPhone using Tapatalk

Hi I have a 17’ Modified V fishing boat. The boat is about 30 years old and I bought it used with a trailer. The trailer is in need of repair and I have been wondering about a new trailer. I just want to confirm that the trailer I have is the correct trailer type for the boat. Just so...

Hi Any idea how to set the idle on an Evinrude 1977 70773S. The shop manual I have walks you through rebuilding the motor but surprisingly has nothing on setting idle speed. Thanks for the help. Sent from my iPhone using Tapatalk

So I popped on 3 carbs from a 1977 70773s and the motor took off like wild. The idle was way too fast. I compared the carb parts from a 70hp and a 75HP and only one part is different. Part #33 Orfice Plug. Any idea what it does and why it is different between a 1977 70Hp and a 75 HP...

My lesson if the day. Got a bit too enthusiastic. Luckily I have 3 others. Sent from my iPhone using Tapatalk

Hi I was rebuilding the carbs for an Evinrude 1977 75743s and while taking off a brass piece that goes straight through the carb body it snapped. It’s a brass piece with another brass piece within it. I can’t find the parts in this diagram...

I had to wait for a few exhaust gaskets to come in but it’s all put together and working nicely. The compression for all 3 cylinders was 105. I will take it for a test run this wknd. If someone could confirm if I have set up the idle speed correctly it would be appreciated. Sent from...

Hi Thanks. I installed the factory ground and it did not make a difference. I had sanded the connections and cleaned them up. I figure the ground solution sounded right so I created my own ground cable and attached it to the same post as the ground cable. Worked perfectly. Thanks for...

Forgot to add. With the key turned there is no continuity between one end of the solenoid and the other. I tried wiring the yellow wire from the main wiring loom to the ‘I’ lug on the solenoid no change. Question: how do you test to make sure the yellow signal wire is doing what it is...

Hi, I didn’t like how the cylinder head looked so I took it off and put it in the parts washer for a few days. Came out really good. I put it all back together and I cannot get it to rotate. In the disassembly and assembly I must have missed something. This is what I know: Battery is...

Good day folks. I took your advice and picked up a used powerhead. I replaced the thermostat, cylinder head gasket etc and popped it on and it works great. I did a compression test and I got 125, 125 and 150. I know they don’t publish compression specs but they are not within 10%...

Hi My son and I went looking for our next winter project.  We came across a Arrow gear Carisma 175.  It’s fiberglass, a deep V and looks to be from the 1980s. It’s pretty trashed but almost free. Trailer is in really good condition. New axle, new tires it just needs to be painted.  Motor...

I don’t get the issue of waiting until I could take a proper picture but if me waiting to do that is causing issues then I am sorry about that. Even if Pappy has told me what the issue was I would have wanted to take the piston out. I don’t learn by people telling me what the solution is, I...
