    I'm looking to replace the ignition coils on my 1977 85hp motor. What were the original OMC part numbers of these coils, and/or the aftermarket part numbers I should be looking for?<br /><br /><br />Thanks,<br /><br />Joe

    Gauge Recommendation

    I don't trust the Tachometer on my boat, and am thinking of replacing it. I have a 1977 85HP Evinrude.<br /><br />My question to those who know more than me is: What is the best Tachometer to use? Should I pony up for a NOS OMC unit on Ebay, or should I go with something in Overtons?<br /><br...

    Tune-up Procedures

    I finally got an OMC Manual for my '77 Evinrude 85hp. It's amazing how much more that book covers as opposed to the Seloc manual.<br /><br />That being said, I want to perform a full tune-up on my motor. I think I understand OMC's procedure for synchronizing the carbs and linkage, but I'm a...

    Differences between 1976 and 1977 Evinrude Motors?

    I'm in need of an OMC service manual and can't justify (to my wife) spending the $50 that it will cost me for the 1977 manual.<br /><br />There's a 1976 manual on ebay that covers the same 85hp motor that I have. Can I use this as a reference when servicing my 1977 motor?<br /><br />Thanks,<br...

    WOT RPMs 77 Evinrude 85 hp (revisited)

    Thanks to everyone on helping me find out why my Evinrude is turning only 4500 WOT RPMS.<br /><br />As per Dhadley's advice, I checked the throttle linkage. It seems that the arm is not completely touching the rubber stop. How should I adjust that?<br /><br />I tested the compression this...

    Tachometer for '77 Evinrude 85hp

    I'm looking to install a new (preferrably OMC) tachometer to replace the older unit currently in the boat. What should I look for in finding this tachometer? I have heard things like "6p" and "12 pole alternator" and "pul/rev".<br /><br />I'm clueless as to what all this means. Can anyone...

    WOT RPMs 77 Evinrude 85 hp

    Last weekend was the first time I took my boat/motor out for a weekend's cruising with a working tachometer. Prior to the weekend, I performed a de-carb just to make sure everything was running well.<br /><br />My boat is a 1978 Glastron 17' with a "semi-v" hull. I just bought this boat and...

    De-Carbing advice

    I just finished spraying the Bombardier Engine tuner into my 1977 Evinrude 85hp. Smoked up a storm....and It was quite an experience using those "muffs". Water was flowing all around my lower unit when I turned the water on....I'm scared that I blew out some kinds of seals or something in the...

    De-carbing at home

    I want to de-carb my 1977 Evinrude 85hp but I don't have a set of muffs. Judging by what I read on this site, it makes a real mess when you restart after spraying this stuff through the motor. I shouldn't think it would be good to run the motor in a "bucket" recycling this dirty water. <br...

    Changing Lower Unit Oil

    I'm going to change the lower unit oil in my 1977 85hp Evinrude (the Previous owner says he changed it, but I want to make certain). My question is: What position should the motor be in to do this? I have it sitting in the "running" position right now, but it has the "tilt" and "Towing"...

    Spark Plug Appearance

    I inspected the spark plugs in my 1977 85hp Evinrude yesterday. According to my Seloc manual, the plugs should be dry and a greyish/tan color. What I discovered was that the plugs were damp (with gas/oil mix) electrodes and all. I also noted that the gaps on the plugs that came with the motor...

    Grease Fitting Replacement

    Last night, in my infinite wisdom, as I was lubricating the various places on my '77 Evinrude 85hp, I broke off one of the grease fittings that go along the tilt shaft near the steering "shaft" (for lack of a better word). <br /><br />Are these fittings hard to find and/or replace?<br /><br...

    '77 Evinrude Lower unit Paint

    Does anyone out there know where I could procure some paint for the lower unit of my 1977 85hp Evinrude (model # 85793s). The color looks to be a greenish grey....but I'm not sure.<br /><br />Thanks,<br /><br />Joe

    Evinrude Hood Renovation

    I just bought a boat with an 85hp Evinrude. The motor is in great shape with the exception of the weatherstrip (for lack of a better word) around the bottom that seals it to the base. Does anyone out there know where I can find this strip so that I can remove the old and replace it.<br /><br...
