    2 hp Johnson: My 2 HP Johnson is a model 2R78R a 1978

    What they are designed to do and what you can or might get away with is not always the same. I have saw many motors run with bad cylinders, but that doesn' t mean they run correctly !!

    2 hp Johnson: My 2 HP Johnson is a model 2R78R a 1978

    Hard to say, all depends on what is causing the change in compression.. Thought you already went thru the carb ?? If not then a definete rebuild is in order, get a factory rebuild kit so you have all new gaskets and the settings needed to get it going. Have you checked the spark ! Jump a...

    2003 50 HP 2 stroke water pump question

    Looks like your on the right path, you might do a spark jump test to see how good the spark is. Buy a good quality rebuild kit for the carbs and do a complete rebuild on them. When you do get it running, a good seafoam treatment will clean out the cylinders. Keep us posted......

    2 hp Johnson: My 2 HP Johnson is a model 2R78R a 1978

    I have never found the little 2-3 hp motors to have anywhere near 100 # of compression. Up in the 10-15 hp range yes and up as the hp gets higher and the cylinders get bigger..

    I would find a "factory" service manual for that motor, then you will have all the information that you need as well as trouble shooting tips.

    Getting ready for the ice and cold in central Texas!

    We have caused most of our own problems like building homes at or below sea level right next to the ocean, or moving to a dry climate for health reasons then irrigating it and planting stuff to create an arid atmosphere !! Then we build giant dams and build a city at the base, then scratch our...

    Is this a salt water motor ? Seems like lots of corrosion or crud.

    2003 50 HP 2 stroke water pump question

    Running on muffs will not confirm the pump is pumping, as the pressure from the muffs will make water come out the telltale. Running in a barrel or on the lake will let you know for sure....however, being a new to you motor, a new water pump should have been done right away !!

    2 hp Johnson: My 2 HP Johnson is a model 2R78R a 1978

    These little motors don't gave much compression, I have the 2.2 hp Merc single and it pulls very easy. Wouldn't want a hard to pull start motor on the back of a canoe !!

    Getting ready for the ice and cold in central Texas!

    It won't be getting better in our lifetime either...people need to make preperations to live with it, rather than fight it by buying EV's thinking everything will change when we do. The climate has gone thru numerous changes over the past hundreds of thousands of years and it takes hundreds if...
