    1977 70 hp johnson thermostat housing gasket

    Same here salt. I have some of my most intelligent conversations when I am by myself. And the answers are almost always what I want to hear. I am planning on a compression test today which will determine stopping or continuing this old complete classic boat resurrection process. I have been...

    1977 70 hp johnson thermostat housing gasket

    Water pump is a fresh one. Don't see any of the used temp parts online anywhere, just new ones for gold prices. Compression test may happen tomorrow, before I start throwing $$$ at it. There are quite a few new parts that were already previously installed. Starter, all 3 coils, plugs...

    Apparently somebody needed all those parts worse than the motor did.

    1977 70 hp johnson thermostat housing gasket

    Ok, did some diagram research. So naturally all of the missing parts require 2 each. Springs, pressure relief valves, and grommets. Ain't it just great. Cha-ching, again.

    1977 70 hp johnson thermostat housing gasket

    So I need help. It is obvious where the two grommets go because they were in there And I removed them. But I have no idea whether the pressure relief valve goes in the upper hole or the lower hole as well as the spring. The outer housing has locations where a spring could go in either hole.

    Okay?So here is an update on my thermostat, housing questions.I've been posting. I took the thermostat housing off And there is no thermostat, no spring, no pressure relief valve. The only thing in there is the two little rubber grommets. This motor has been sitting up for a period of time so...

    1977 70 hp johnson thermostat housing gasket

    In My particular application, every (kit) listed only comes with the tstat, tstat ring seal , and the cover gasket. Any other internals would have to be ordered separately, piece by piece.

    1977 70 hp johnson thermostat housing gasket

    1977 70 hp johnson thermostat housing gasket

    Yep, saw it now. What about the spring and that pressure control valve. Replace ?

    1977 70 hp johnson thermostat housing gasket

    I only see 1 grommet in the parts breakdown page aside from the ring for the thermostat itself. Should I do the spring and the pressure control valve too? Or should the spring and valve be OK unless grossly gunked up.

    1977 70 hp johnson thermostat housing gasket

    They appear to be. I will probably apply a very thin film on the Gasket, not even enough to ooze out.

    1977 70 hp johnson thermostat housing gasket

    Yep I think I have the grommets too. I would probably just put a very thin film of sealer on both sides of Gasket, hardly enough to ooze out.

    1977 70 hp johnson thermostat housing gasket

    I am soon replacing the thermostat and gasket on my 70 hp 1977 Johnson. Should I put RTV silicone on the gasket material or install it dry. And if the silicone is recommended, is the black the best , or is the blue or red just as good.

    1977 Johnson shift/throttle control box

    So, at this point, I am on the hunt for a Johnson control box with NO tilt/trim and preferably with the red plug but if it is the newer unit, up to a 95 year. I can order the needed harness to adapt it. I have noticed that on the newer ones, the shift/throttle cables appear to be quite easy to...

    1977 Johnson shift/throttle control box

    And I would guess that the newer style may be more plentiful at a salvage yard.

    1977 Johnson shift/throttle control box

    So if I get a newer style controller box, get the correct adaptable red plug wire harness, and new cables, if necessary, it should work like a charm.

    1977 Johnson shift/throttle control box

    Hey racerone, when you say you are too far away to help with one, does that say you may have access to one ? Like what I am looking for ? What is your location as well. I may end up having to go newer style, but I am trying to keep everything all original if possible. Thank you.
