    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    No readings are taken from the trigger-wires to ground only between the sets (#1/#2/#3/#4) With all the wires still disconnected; take a volt-reading(with a DVA-adapter attached to your meter & meter set to DC volts) (1) from each set of trigger-wires = should around 4.5 volts (2) from each set...

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    I'm struggling with these issues myself & for myself to simplify this; I disconnected ALL the trigger-wires from the terminal-bar to eliminate any false readings & clarity (1) verify you're taking a reading from the correct trigger-wires (per set) Then disconnect all the Stator-wires (except...

    As the gear-case where not "labeled" with stamps, the only way to know what you got would be either look for a date stamping in the cast or by counting the revolutions of the drive-shaft v.s. prop-shaft

    The white plastic adapter is just pressed on the copper-tube (unless someone glued it) DON'T pull the copper P/U-tube out!! Hold the P/U-tube in place & try then by making a twisting motion while pulling on the adapter. IF all fails.........you could break the adapter off the tube so you can...

    Force went to a 2-piece shaft (on the 85HP & some other) in '88 so they could use the same as the one used on the L-drive units The later version you have came in '91/'9 B model & many other version followed. Believe me when I say; it comes off, I do it every time when I have a motor just...

    The are both Force/US-marine lower-units (there is A later Merc. version(s) that are not compatible)the two you have still are. The white plastic-adapter on the copper P/U-tube will come off & you can slide on the preferred one However the water-pump housing & plate can not be swapped-out

    Can I swap factory tilt/trim from Mercury version 85hp to US Marine version 85?

    I'm not sure if I'm getting this right? Does the "earlier LU" have a two piece OR one piece drive-shaft? The one piece came in two lengths 20" & 25" IF the length is correct; it should fit??? Hopefully jerry jerry and/or Nordin will tune in and verify the year(s)

    The "upper pivot bolt" as you refer to, that the the two clamps together rarely come out/apart In the top picture is still a US marine with (maybe) a Merc trim motor & apparently with typical Merc. clamp-down bolts. As for the motor on the boat.....looks to me like the old Chrysler cowl Jerry...
