    carb or ignition problem?

    1988 Evinrude 25hp motor. Starts easy on 1st pull, but seems to idle a little rough. It will stay idling and idle low, but the motor seems to shake more than its supposed to. I might be wrong there, but the main problem is at WOT. When I open it up it just flat out runs rough. Itll almost...

    prop for my jon boat - 25hp evinrude

    I have a big deep and wide flat bottom boat. Its 14' and 48" wide at the floor. I was wondering if the prop that is on my motor is right for what I do. I took it out today and it seems like when I put that last little throttle, it tops out really quick and isnt responsive as much as it should...

    Homemade transom elevator question

    First, sorry no pictures yet. I forgot to take some this morning before I came here to work. I built a transom elevator for my longshaft with 4 pieces of equal size cut angle aluminum. At the top I bolted a 2x6 (most of you know its actually 1 1/2 x 5 1/2). My transom is 1 1/2 thick so this...

    25hp - 1988 vs 1983

    I currently have a 1988 Evinrude 25hp motor, but its long shaft. I have a guy that is willing to trade a 1983 25hp motor, short shaft (which is what I need). I was just going to check and make sure there wouldnt be a big power loss. Was it 1983 when Johnson / Evinrude started rating their...

    1988 25hp - spark issue

    Not getting any spark on the lower plug. Put new coils in it and even switched and the problem stayed on the side. It didnt follow the coil, so its not the coils, not the wire, and not the plug. I have confirmed all that. What is next to check? Does this model have sensors under the...

    my 9.9 vs 15

    Well I own a 76 15hp motor and now recently I just got a 87 9.9. Today was the first run I have had with the 87 9.9 since I just completed overhauling the carb and replacing the impeller and the water pump seal. The 87 9.9 seemed real comparable to my 76 15. I was surprised. How close are...

    I have a 87 Johnson 9.9 It was given to me...the motor runs perfectly, but looks like total crap. I was wanting to repaint it and I was wondering if there is a certain type of paint you are supposed to use as far as oil / water based, or enamel, etc... I am not going to get the OEM from...

    87 Johnson 9.9 manual recoil

    mine binds up when i tighten the bolt to where it wont retract. I am about to pull it off and see if the washer on the bottom of the casing is lined up and I know this can be caused because of that, but is there anything else that can cause this?

    electronic ignition

    I just started working on an 87 9.9 Johnson motor. This will be the newest motor I have ever owned, and the only difference is the ignition components. This one is electronic ignition. Could someone just briefly explain to me how electronic ignition works and when you are maintaining it, do...

    which spark plugs

    1974 Chrysler 15hp getting new ones, and dont have the manual to see what it calls for. The ones that were in it were J6c's...I know thats usually a bit hotter plug for these motors but the guy that had the motor before me did alot of trolling on a sail boat I believe. thanks Matt
