    Decarb and WOT questions...

    I was reading the Decarb FAQ and I was wondering what the purpose of a separate gas tank was? Could I not just add the seafoam to my existing gas tank? The reason I wanted to do a decarb is the idle is a little rough on my 1990 90hp Johnson. She has a tendancy to stall...if the motor is...

    Torque Question...

    I was torquing down my flywheel today (first time using a torque wrench) with a borrowed torque wrench from my brother in law - he is away on vacation so I can not ask him any questions now - but it is the type where you twist it to the ft/lb setting on the handle and it gives one click when it...

    In the middle of installing Regulator/Rectifier...

    and part of the gasket was stuck on...I used a utility knife blade to clean as much off as I could - how clean does this need to be? I have some 3M Scotch-Grip Rubber & Gasket adhesive to apply to both sides of the new gasket... Also I had to loosen the black ring (I think it is the...

    Flywheel Torgue Setting

    I finally got my regulator/rectifier for my 1990 90 hp Johnson. I need to remove the Flywheel to remove and replace the regulator/rectifier, but I do not know what to torque the Flywheel to when I put it back on. Also, anything else I need to watch out for when I take the Flywheel off and put...

    Tach Question...

    Last year, I started having problems with my tach - it would rev up then slowly die. I checked connections at the control box and at the tach - pushed the 3 pin connector at the control box in to make sure it was seated properly. Same behavior occured with the tach. I read on here that I...

    Prop Damage?

    I was wondering how bad it is to run my motor (1990 90hp Johnson) with a prop that has a little chunk (1/8 - 1/4" x 1-1/2") out of it...? I did not notice a performance change after the prop hit something... This happened a few years ago and I was told at the time that if I did not notice a...

    Changing Lower Unit Oil

    I changed the lower unit oil in my 1990 90hp Johnson last fall when winterizing it. I did not replace the washers on the drain plug and vent(?) plug at the time because I did not have any. I think I read on here that it is a good idea to do so...what is the reasoning behind this? I picked...

    Octane for 1990 90hp Johnson?

    Hey guys, I did a search, but I can't seem to find the answer to my question. I bought my boat about 7/8 years ago from the original owner. He said he had always ran premium gas in the motor, so I continued with this. Now, after seeing a few others posts concerning this and stating that only...

    Stuck in Reverse

    Hey guys, I ran into a little problem on the weekend. I had my control in reverse and moved it to forward and the motor stayed in reverse. I can move the control freely but the motor stayed in reverse. When I moved it forward it throttled up and went in reverse faster. Is this most likely a...
