I got this motor last year, replaced thermostat, lower unit oil. impeller rebuilt carbs and did all the little tune up stuff I could think of. Most of the time it ran decent however some times when it got over 4000 rpm's it would surge like it was starving for fuel. Some times it helped to pump...
1991-70hp rude 70tleie
After a night of fishing while pulling up at the dock this morning after about a 15 mile run up the mississippi river, I noticed steam coming out of the upper exhaust holes. It was still peeing. I took off the hood and it did not seem to be over heating. Before I order a...
My 1991-70hp rude surges when cold. It will run fine to about 4000 rpm and then starts surging. After 5 or 10 minutes it runs fine. I think 5 or 10 minutes is too long to warm up. It has a brand new thermostat.
I have a 1991-70hp rude, tach not working battery not charging. I have the omc manual. It says the reading on the stator wires should be 1.4 ohms. I am getting 2.1. I have two other stators that I tested with same meter, I get same results. 1985 and 1987 both 70_hp. I'm not much good at...

1991-70 hp rude
I had my boat out and felt the head to see if it was getting hot. It was cool, too cool, so I took off the Thermostat housing and no Thermostat. I just got this thing running and wanted to know what damage could be done to a motor which never reaches operating temperature. I...
My 1991-70hp rude omc manual says to never soak carbs in carb cleaner. It says to clean the carbs with a mild aerosol solvent. It even shows a picture of gumout being used. I have been soaking carbs as I read in here that it is the thing to do. It also says to use no more than 25 psi to blow...

I need a factory service manual for a 1991-70hp evinrude so I went to ebay and typed it in. I found several "real service" manuals for that hp and year. However, they all covered 60-65-70-hp. My question is will this cover what I need to know or is there a manual specific to that hp and year?
I got rid of my 1985 70hp evinrude and picked me up a 1991 70 hp evinrude. The guy said it had been sitting for a year. I got it home and it started right up. It seemed to have a miss so I checked the compression,120 times 3. Got out the spark tester and it has a weak spark on all 3. The power...
I have 1983-70hp carbs never could get it to run right "bogs down" Anyway, I have discovered the needle valves are missing as they are shown in the blow up pic below. Was this because of some kind of service bulletin?
I have a 1985-70hp rude I tried to put carbs on it off a 1987-70 rude but it still bogs out. If I use the 87 intake manifold and reeds do you think it would work then?
Anyone know where I can buy used carbs for a 1985-70 hp evinrude? I put the carbs on a 1983-70 hp that I sold. I have tried carbs off a 1983 and a 1987 and no matter what I do it still falls flat on it's face. I guess i need the right carbs.
