    Compression

    Ok, went and got a higher end compression tester to see if my obviously cheep one was junk. The original readings were all 3 between 70-80. The better guage shows top-115, mid-110, and bottom 120. I assume these numbers are acceptable for a 1977 year motor ?

    Compression

    Will a mid 70s 70hp Johnson still run decent with the compression on all 3 cylinders averaging 70 to 80 psi ?

    Old humminbird dial flasher inline fuse specs

    Yea I have seen some very inexpensive modern day units out there. Just not my thing, yet. I grew up with the old lowrance eagle and the humminbird 60/super60 units. Never had an issue , not one. After every trip out, even if every day , I always remove/removed the unit and stored it...

    Old humminbird dial flasher inline fuse specs

    Old humminbird dial flasher inline fuse specs

    I can't seem to find any info anywhere about what inline fuse size should be for an old school dial flasher. YES, I HAVE LOOKED IN THE MANUAL and it mentions nothing about that. I seem to possibly remember many years ago on my other units it was maybe a 1 amp, not sure tho. No info anywhere...

    Lubricate new water impeller rubber ?

    Since our yays and nays pretty much were even, we agreed upon "to each his own" . I take the thin film route, but I am an over doer with just about everything.

    Lubricate new water impeller rubber ?

    I have seen various methods people use when replacing the water impeller in an older Johnson 60-70hp. Some say they like to apply a tiny film of some kind of slick um to the metal cup and I have heard some say to put er in the cup dry and that the water will.lube it enough. Not so sure...

    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...

    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.

    1977 70 hp johnson thermostat housing gasket

    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

    Plenty confident. I just dont like to have to go back and do something twice or half way. I was looking for a kit but couldn't find one as of yet but ain't giving up on the Search yet.
