    Johnson 90 hp a weird one

    I am thinking the same thing , even though the boat was bought way inland doesnt mean a thing. I know the water flooding out of the mid section is pretty common but it never did it before and now i am sure my motor is over heating. I planned to pull lower unit and thermostats this morning , but...

    Johnson 90 hp a weird one

    I know the tale tell does not mean the engine is actually cooling the engine. But if the block gets hot enough the water will get warm. I have seen it and stopped a few boats in my time that were blowing steam out. What problems they had i dont know? Maybe an air pocket since some of them are...

    Johnson 90 hp a weird one

    This boat was rewired and temp gauge never got over 100* This is the only place the water was slighly warm. I am assuming thermostats clogged and water only circulating through the poppet valves. But the water is leaking bad between the lower unit Only place water slightly warm

    UPDATE Check temp sensors all showed OL So none are bad, grounded them all to block and did not hear an over hear alarm. Checked plugs two lower cyclinders plugs are a little wet. I probably have the float setting off. Checked compression , all 4 at 120 psi.

    What type of gas tank for '79 Johnson 35hp?

    The new EPA plastic boat tank i bought was a 12 gallon tank, they dont vent to the atmosphere. They only let air in when you open cap valve. Just read the tanks description before buying a plastic tank. Mine would swell up about an inch in all directions with the cap tight in the sun. The cap...

    Johnson 90 hp a weird one

    I removed them at the lake when it was acting up. All plugs a little damp and using my remote starter And a copper wire for ground on all the plugs they were all firing. They are new and i bought the same type that was in it. I am assuming the old ones were correct. I carry every tool i can...

    Checked that on the lake with carb cover off , trigger moved to full advanced and but carb butter flys were open dead center, and ran it back to ramp with cowling off and watched it while i accelarted and decellerated. Just to make sure something was not acting up. Thanks

    1981 70 Johnson. How to manually raise motor...

    On the opposite side of the motor the motor thier should be a stainless slotted screw for a flathead screw driver that you can turn left that will allow the cyclinder to bypass the oil then you can lift the motor by hand and tighten the screw, or it will leak back down rather slowly or fast...

    Johnson 90 hp a weird one

    I am going to work on it tomorrow hopefully! Going to start by ohming out temp sensors to see if one is bad. Check compression . Check spark at cranking speed and at full throttle. Check trim sensor in case it thinks motor is out of the water since i was trimming it up and down on the way back...
