    Anyone recognize one of these?

    I might have saved this old motor from the scrap metal pile - just wondering if anyone knows the year, thrust, etc. It is a vintage MInnKota, Model number: CDR, Serial number: 32476. Looks to be in relatively good shape - havent tested it out yet, but I wanted to repair/restore it. Anyone...

    Uneven Cylinder Temps

    I have been fighting this cooling issue for a while now and now I have no other ideas. Engine is a 1990 Johnson GT200 (VJ200SLESE). At idle, Port cylinders read close to 160, if not a little over. STBD side cylinders stay around 108-110. Compression is around 90psi on all 6, good spark, and...

    Part 2 of 2: Water Leak from base of Power Head?

    Second Video. Whats up with this water leak? Never touched this part of the engine, only the STBD Cyl. Head. Should I be concerned about this? (1990 Johnson GT200 VJ200SLESE)

    Part 1 of 2: Verify Spark?

    Due to site restrictions, I can only upload one video per post, sorry. Spark: Overall, most cylinders jump a 7/16 gap. A couple are still suspect (2 and 6)- not sure if I needed to keep cranking the engine or not. Got a little anxious because I didnt have the hose hooked up (brand new...

    Surprise! When I took off cyl. head...

    Re: Surprise! When I took off cyl. head... Funny you should ask... While I was attempting this whole thermostat upgrade, one of the bolts for the thermostat cover broke off. And when I say "broke off", I mean this thing seized up so bad- twisted the head of the bolt right off with hardly any...

    Surprise! When I took off cyl. head...

    Got a nasty surprise today when I removed the STBD cylinder head. I used a can of OMC engine tuner when I first bought this boat (2yrs ago). Other than that, no decarbing- thought that was enough. Boat is rarely used anyway. What would be the best method to remove all of this carbon from...

    1990 Johnson V6 T-Stat Conversion

    Re: 1990 Johnson V6 T-Stat Conversion Thanks boobie. Now Im curious... Which thermostats do I keep? From reading this post, it sounds like I should keep the old housings, just switch out the vernatherms. If so, can I keep the existing seats? Heres what ezeke said:

    1990 Johnson V6 T-Stat Conversion

    There are several threads related to this topic here on iboats, but none are specific to my question. Most threads list the part numbers needed and the fact that doing this "upgrade" gets rid of some unnecessary hoses as well as eliminating the water control valve. I now have all of the...

    Need help understanding thermostat "upgrade"

    1990 Johnson GT200 (VJ200SLESE) So Ive been reading up on thermostats and discovered that there is a thermostat "upgrade" available for my engine to bring it up to standards of a 1993 model. Found some very helpful threads , but still have a few questions (keep in mind that I am ignorant on...

    Replace Water Pump now or next Spring?

    1990 Johnson GT200 (VJ200SLESE) I have noticed the past few times I have been out that it is taking the engine longer than 10 seconds to start "peeing". The water pump was changed out a little over a year ago (14 months), so it is about time for a new one anyway. It looks like it spits out...

    Wise to bypass vacuum switch? (1990 Johnson 200)

    Engine: 1990 Johnson 200 (VJ200SLESE) Last Friday I installed rebuilt carbs and changed out ALL fuel lines on the engine. In the process, I believe I might have pinched or damaged one of the wires on the vacuum switch (fat hands). I realized this yesterday when I had the boat out on the...

    1990 Johnson 200 Fixed Jets?

    Guys, Over the past few days, I have came across a multitude of problems with my engine (1990 Johnson 200GT, VJ200SLESE). I have discovered a stuck float in one of the carbs, and have been trying like hell to figure out the "coughing/sneezing" at idle speed issue. After some research on...

    Should I run this engine dry before leaving the ramp?

    So I am trying to troubleshoot a fuel leak and I have came across some posts that contradict what everyone has told me since I have owned my boat (little over 2 years). The engine is a 1990 Johnson GT200 V6 (with oil pump disabled- bought it that way). Is this an engine that needs to be ran...
