    Port/Starboard Jets for Carbs or Pistons?

    1986 140hp has different intermediate jets for the port and starboard banks. I rebuilt the carbs but didn't make a note of which went where so i went to the Evinrude site to see the configuration. When they say the port-side, do they refer to the port-side carbs or the port-side pistons? The...

    1986 140 Small Bore to Big Bore

    Ok, so I bought the motor a few years ago and it kept getting jammed when trying to turn it over. It turned out that one piston was completely coked up and kept jamming in the cylinder. So, to go cheap, I just replaced the rings on that piston and cleaned all the pistons of any carbon. I'm not a...

    1986 Evinrude Rough Idle

    The engine is a 1986 140hp Looper and it constantly has trouble idling without it sneezing and killing itself. After a good long run it will idle longer but still will sneeze after about 3 min. of idling. If i raise the RPMs it has no problems but it won't idle at 900 RPM. I did a link and sync...

    Intermitent Clicking Noise

    I've got a 1986 140hp Evinrude with VRO being used. Last time out, idling out of the no-wake zone, the no oil horn kept going off after every 5 min. of running it until I decided to pump the oil primer bulb once, then it went away. It ran flawlessly until we were putsing back in to the ramp and...

    1986 140 hp Looper High Idle

    I just got finished redoing my lower unit with new seals and new pump and i also realized over the winter that I had two intermediate jets wrong. I put it all back together today and i can't seem to get the idle down. Its at 1000 RPM on the muffs but i got a cloth over the prop to simulate back...

    1986 140hp Looper Top Performance

    Well, I got a 140 looper with a v4 style lower unit and I got it paired with a 1989 Checkmate Predictor which is 16' and weighs in around 900 lbs. I'm looking to get the best possible speed from the engine. I don’t want to go with a v6 because I can’t afford to buy one and they’re a pain to...

    1972 Cobia Holiday

    I got a 72' Cobia Holiday 16' and its never had any paint on the hull but it has pitting on it. I was wondering if anyone knows how to get rid of the pitting? Do i fill them in with something or, because they are shallow, sand it down smooth? And if i paint it with a teflon paint, will that...

    Fuel Economy

    I rebuilt a 1986 140hp with VRO just at the end of spring this year. My boat had a 1979 115hp and I rebuilt that one a year earlier. With the 115, my boat got great gas mileage and ran great. The 140 with the VRO connected gets worse gas mileage and it doesn't like to idle. My question is: I...

    1981 Evinrude 150hp to 200hp?

    Is the carbs the only difference between a 150hp and a 200hp? I have the 150 and according to previous posts, it seems like all I have to do is change the carbs to ones from a 200 and have a 200hp. Is this true? My boat will hold up to a 175 and i'm looking for that extra push. I know that the...

    1986 140hp Swivel Bracket

    I took the steering assembly off and after hours of beating I finally got it apart. It had very tight steering and I found out that the upper seal of the swivel bracket was destroyed. So water entered and made the steering tight. Everything else is fine but I can't locate a new seal. Does anyone...

    1986 Evinrude 140hp Won't Turn

    Its a loop charged and it won't turn over comptetely. The Lower unit is off and the engine only rotates half-way.It rotates freely for about a 1/4 turn and the other 1/4 it gets a little stiff but it frees up as you turn it more to the end of the turn. I took the heads off and the cylinders are...

    1981 150hp Evinrude Connecting rods

    I bought the engine on eBay for a good deal. It came apart because it had scored walls but was already repaired and ready to go back together. However, I noticed that 3 of the connecting rods had been grinded down on the sides to remove the lip. I just wanted to know maybe why they were grounded...

    1979 Evinrude 115hp not above 2000RPM

    OK. I've just rebuilt a 1979 115hp Evinrude and it won't go above 2000 RPM. I move the throttle to a certiain position and if i push it any further the engine has no response. I have the carbs and ignition synced and the throttles set up correctly, but i can't check the timing. It idles great...

    1986 140hp Johnson

    The engine still runs but it makes a knocking sound. Any ideas on what would be causing it and how much to repair? :confused:

    1981 Evinrude 115hp piston top ring?

    I am aware that the mid to late 70's model engines had a high top ring grove that would fail because of carbon build up. My question is did that extend to the 1981 115hp engines as well? Or when did they change the design of their pistons before then? Thanks

    1988 88hp Evinrude P T/T

    I have a 1988 Evinrude 88hp with manual tilt. I found a power trim/tilt on eBay and I'd like to know if I have to change my brackets or anything to accommodate the unit. The seller says it is the correct model power trim/tilt for my year and size motor. Thanks.

    1977 Evinrude 115hp

    Will a newer power trim/tilt unit, with the double trim rods and single tilt rod, fit my engine? The engine originally came with the single trim and single tilt rod with the externally mounted motor. Would the newer models work?

    1979 115hp Evinrude piston design?...

    This is more of a question that'll help prevent trouble. My father owned a 1977 115hp Evinrude and the piston went because the top ring land was too close to the top of the piston, so it had no strength. He claims that they corrected this in 1979. Is this true? Did they increase the space...
