    1988 90hp no spark.

    Hi all. Im helping a friend fix up a boat with a 1988 Merc 90hp 3 cyl motor that has been in storage for 2 years. The motor was properly winterized by a marina in the fall of 2008 and was in good working order at that time but now there is no spark. We have checked for obvious things like...

    Why is my 110 Johnson misfiring?

    First of all, I apologize for the long winded post, but I want to provide as much detail as possible. Just got back from a week at the lake and Im looking for a little advice on diagnosing a stumble or misfire on my 1988 Johnson 110. The motor runs very smoothly at idle whether in neutral at 750...

    Need a 13x19 non cupped i think?

    Hi all. I am currently running an 13.25 x 17 pitch aluminum prop on my 16' aluminum bowrider, the motor is a 1988 Johnson 110 hp. The WOT RPM is 6100 and it gets there fast, which is just a little bit high from what I have read in this forum. I wanted to bring the RPM down to around 5800 so I...

    Ignition wires O.E. or generic aftermarket?

    Last summer I had a misfire only at low RPM on my 1988 110 Johnson (J110TLCCA) and I determined that the 2 port side cylinders were not firing consistantly. I made this determination by deliberatly running at low speed for several minutes and allowing the misfire to occur, I then killed the...

    What year? (FAQ checked)

    Trying to find the model year of a Canadian 50hp 4 cyl Mercury outboard. As stated in the subject title, I have checked the FAQ but the links only seem to provide info on US models with the exception of maxrules and unfortunately their listings are incomplete for Canadian models. The serial...

    1973 40 Hp Lower Unit Swap

    I have a 1973 Merc 40hp 2 cyl (7015410 Canadian) that needs a new lower unit. Found one for sale from a 3 cyl 65hp believed to be a 1976 but no serial number to confirm. Is there any chance that this lower unit will work on the 40hp?

    1988 Johnson 110 Misfire and cooling issue.

    My 1988 110 Johnson runs great at one quarter throttle and above but when cruising at very low speed or taking off after it has been run at slow speed it has an annoying mismire. I have checked the timing,, done a link and sync and cleaned the carbs but the problem persists. Today while...

    Engine height on transom. Did I go to far?

    In my quest for more speed I have raised my motor up one hole setting on the transom but now the boat porpoises unless it is trimmed all the way in and I put additional weight in the bow. Here are the details on the boat... 1987 16.5' aluminum bowrider with a 1988 110hp Johnson. Heres the deal...

    1985 60 hp cant find right impeller??

    Helping my buddy put a new impeller in his 1985 60 HP Johnson and the new impeller we bought is different, the one on the motor used a wedge style pin and the new impeller used a dowel style pin. We ordered the part as per the model number on the motor so I was surprised to see that it was...

    Hose clamp opinions needed.

    I am replacing some fuel and oil lines on my 1987 Evinrude 90 and the service manual tells you to use the special snapper type hose clamps, it even warns you not to use traditional metal screw type clamps or cable/zip tie clamps. Not to suggest that there isnt a valid reason for this but I have...

    Grinding noise from power trim.

    My 1987 Evinrude 90hp is making a grinding / rattling type noise when I trim up. The noise can only be heard when going up, down is normal. Also, once the motor is trimmed up/out to the point where the trailering motion takes over and the tilt moves faster, the noise goes away completely. It...

    VRO leak, I think I know the answer but...

    My new to me 1987 Evinrude 90hp has a bad fuel leak at the back of the VRO pump. I have determined that the leak is coming from the pulse pin o ring for the "No oil flow" alarm. I noticed the leak when I was pumping the primer bulb and it is a severe leak, not just a little bit of seepage. Is...

    What happened to my trim guage?

    I was hooking up my trim guage today for the first time since replacing the motor (88 Johnson 110 and OMC guage of the same vintage) and when I turned the key on the needle in the guage shot all the way to the top and stayed there even after turning the key off. I have 12 volts coming into the...

    Transom Repair Pvc Zodiac

    What is the best glue to bond the pvc floor fabric back onto the plywood transom? Seems to me that the pvc glue works by actually melting the material and when attaching pvc to pvc Im sure is quite effective, but I question how it would bond pvc to wood since the glue obviously wont melt the...

    1988 Merc 60 wont shut off

    I fired up my 1988 Merc 60hp today and I couldnt get it to turn back off. I turned the key off and removed it but it kept on running. I turned off the toggle switch below the key and it had no effect, the motor kept running. The motor is not on a boat, it's on a stand in my garage. The motor was...

    Lower unit gear ratio 1988 110 Johnson.

    I suspect my "new to me" 1988 Johnson 110 has had the lower unit replaced at some time as the colour is different than the rest of the motor and it looks older based upon it's general condition. I have this motor on a boat that is rated for max 90 hp only, so it's got power to spare and it runs...

Anyone know where I can find...

Also what would 60 prop rated hp = in the older crank rated models? I am selling this motor and a guy is mildly interested...
