    STUCK!

    About to change the water pump on a 70 HP 1987 Johnson. Managed to lossen the (4) bolts after heating and some pursuasion. This lower unit hasn't been looked at in some time! Looks like it was run in the salt. The driveshaft won't come apart and free itself so I can further drop the bottom...

    Tell tale weak?

    If a somewhat pee line seems weak, is it necessarily a problem? Isn't the tell tale a visual aid only and the spent warm water coming out the (2) holes below the cowling on a 87 70HP Johnson the actually discharge?........L

    gas gauge for Johnson 70HP!

    I recently bought a 1986 McKee Craft 16'. Everything is up to par now, thanks to all of the wonderful information shared at this forum. The only glitch is the gas gauge. Original built in boat, tank, 16 gallons. The gauge is original as well. The gauge is all over the place with different...

    Plugs look rich?

    1987 70HP Johnson, new plugs after going through about 10 gallons of gas. Shouldn't they be dull gray looking instead of this black sooty oily look? Any suggestions? WOT 5400, idles aroung 1000, any lower will die. Compression in bottom hole is 10 less than other top two.........L<br /><br...

    Rudder broken!

    On this 70 HP 1987 Johnson, I noticed that the rudder, skag (don't know the correct nomenclature) is broken enough from past owner that the prop would hit an object before the rudder would. Can these be helio arc welding (aluminum) to create a longer extenstion on the rudder. I would imagine...

    Tilt/Trim fluid???

    The fluid is low in the reservoir of my 1987 70 HP Johnson. Can I simply go to the auto parts store and buy automobile power steering fluid and use that to fill the tilt/trim? Thanks in advance..........L

    70 HP 1987 Johonson won't idle unless......?

    unless......I kick up the idle adjustment screw to 1500 RPM's + or -!<br /><br />Is that too fast? If I reduce the idle to around 1000 RPM's it dies!<br /><br />Trolling speed at 3.5 MPH at 1100 RPM's works fine.<br /><br />WOT is at 5100 RPM's at around 40 MPH. Should this be higher?<br /><br...

    Gas can confusion?

    To get my 70 HP Johnson 1987 on target with the boat I recently bought, I have been using auxillary Evinrude 6 gallon gas cans 50:1 mix instead of the old gas in the boat's gas tank! I noticed the 6 gallon containers have no vent in the cap. Is that normal? I am use to venting all of my smaller...

    You mechanics out there!

    Has anybody heard of the term "pick up timing"?<br /><br />I am having this trouble when shifting from a stable idle and then into gear where the motor will die. To prevent this so I can get on top of the water, I need to idle fast and then rapidly shift into gear and hopefully it will pick up...

    Scenario! 1987 Johnson 70

    What would you do?<br /><br />Had mechanic look at this motor today and the compression checked at 120psi, 120psi and 95 psi on the bottom hole. I don't have the money to think about a new 70 at this time. I have never run this boat motor before! How bad is it to run this with that low...

    Where is the choke located on the controls for a 70 HP Johnnson 1987? Thanks in advance. Is it the part that lifts up on the top portion of the controls? Also what is the black button located on the side? Thanks again.

    1987 Johnson 70 VRO froze!

    I am new to this forum and I am amazed on how knowledgable and generous the forum members are. I just purchase a 16" Waccamaw McKee 16 foot boat with this 70 VRO Johnson. Very little info other than it was last registered in 2000 when the motor froze. It has been sitting ever since with the...
