    1987 8hp Johnson problems

    I went to change my impeller today and when I disconnected the lower section, it was loaded with a greenish goo all over everything. Definitely smells like gas. Drained lower unit and it was clear. Won't let me download pic off my phone. Last time out, the telltale plugged up and I shut the...

    1988 90 hp v4 plugs

    Motor hasn't been running good. I have replaced plugs, plug wires, coils, tried spraying carb cleaner through carbs, put seafoam in gas tank and I am only getting 2800 rpms at WOT. Just ran it for about 15 min in my driveway, then checked compression and got 120 on all 4 cylinders. Pulled the...

    1988 90 V4 question

    Finally got my boat out yesterday on Lake Erie. The lake was pretty flat and as I sped up, I moved the throttle handle all of the way forward. It was showing about 3600 rpm's and I was going about 28 mph. When I first bought the boat 3 yrs ago, I never came close to moving the handle that far...

    90 hp revving up on its own

    Finally got my boat out yesterday. 1988 Johnson 90 hp V4. Started up well and idled nice. Got started out onto the lake and got past the breakwall and gave it some gas. As soon as I got past 10mph, the motor revved up like crazy like up to 5000 rpms and it almost felt like we weren't even...

    1988 90 V4 propeller

    Just pulled my prop to check seals and when I put it back on, it just doesn't seem to go on far enough. Everything is in the correct order that it was when I took it off. What is the torque setting(if there is one) for the prop nut? When I first removed it, it didn't want to budge. I sprayed it...

    1988 90 hp V4 prop seals

    Just noticed a small puddle of oil in yard where boat is sitting. Oil is coming from propeller. Can you replace the prop seals without taking the whole lower unit apart?

    1987 8 hp Johnson throttle

    I am using a 1987 8hp Johnson as a kicker on my boat. Is there a way to lock down the throttle once I get up to the trolling speed that I want. Throttle seems to vibrate down.....I have been using electrical tape to hold it in position!

    1988 90 hp Johnson V4 leaking oil

    Finally got my boat out a couple days ago and it ran good. After I put it in the garage, a couple days later I noticed a little puddle of oil underneath the propeller. So I am guessing that there must be some kind of seal that is bad. Has anyone ever changed one of these? Can the average guy do...

    1988 16.5 ft. nordic crestliner

    I bought this Crestliner last fall with a 1988 90hp Johnson. When I run it, the faster I go, there is a lot of water on the port side that shoots straight up and starts filling that back well on the boat. My buddy said maybe it had something to do with the transducer being mounted on that side...

    transom saver or trailer bracket?

    I purchased a 16.5 ft Crestliner with a 1988 90hp v4 Johnson last fall. It has a bracket that you just flip down when trailering. I was thinking of adding a transom saver because the bracket doesn't seem like it is big enough to support the motor. I sort of worry about hitting a pothole and the...

    1988 90 hp johnson v4 service manual

    Anybody know where I can get a 1988 90 hp Johnson V4 service manual. I bought a manual from Seloc and don't really care for it. It reminds me of a Chilton's manual for automobiles. I haven't had any luck locating an actual manual for this model and year of motor.

    1987 8hp johnson fuel mix

    I have a 1987 8hp Johnson that has a sticker on it that says to mix 100:1. A couple people told me to mix it 50:1. What do you guys think? I am thinking that you would have better lubrication with the 50:1 mix but it would smoke a little more. The guy I bought it off of was mixing it 100:1. Thanks.

    1988 90hp electric fuel primer

    Looks like I have a small fuel leak on the manual lever and I was wondering if there are rebuild kits for these fuel primer assemblies or do you have to buy the whole thing. Thanks.

    1987 8 hp Johnson question

    Please forgive my ignorance in regards to the following questions. This is my first boat and motor so here we go. I started the motor in large container of water and water is coming out of the pee hole, but not as well as the stream that is on my 90 hp. After I ran it for about 3-4 minutes, I...

    question about rollers on trailer

    Re: question about rollers on trailer For some reason, my close up pics of the rollers won't download. Maybe somebody(my wife) changed some setting on my camera. Here is a picture of the boat...not sure if you can zoom in on the rollers or not.

    question about rollers on trailer

    I just bought an older 16 ft. Crestliner(1988). It sits on an EZ Loader roller trailer. When I got it home and really looked it over, I noticed a lot of little creases on the bottom of the boat. I was thinking that maybe the rollers don't move freely enough and that they might be causing this...
