Mercury Tilt Trim Cylinders 1960's to Late 80's Working PAIR Please Read Listing

Description

Note: I just
raised
the price as even at 9, you can't touch a
pair
of these cylinders in working condition!
I have a PAIR of serviceable trim cylinders that were used on 2-cylinder 35 and 40 hp, 4 cylinder 45 and 50, three cylinder 50, 60, 65, and 70, and "big 4" 65, 75, 80, and 85 hp, plus inline-6 Tower of Power models from the 1960's right up to mid or late 1980's.
Part number cast into one is 78439
but that is probably just the housing - I don't have a part number for the entire assembly.
I was asked about collapsed length and as near as I can measure it mounting stud center-to-center would be 8.5" or 8.75" -
I don't think these came in alternate
sizes
but you Merc guys might know better than I.
These hold trim position fine and don't leak a drop externally. They've been on a friend's boat for two seasons without a major problem but he complained of slow [2-3 day] leak-down from the full tilt position so they've been removed and replaced with freshly rebuilt cylinders.  If yours are leaking fluid out or won't hold pressure under engine load, here are your affordable replacements.  I wouldn't hesitate to install these on any older Merc to get the trim in operable condition;
as long as you use the trailering support to hold motor tilted when not in use you should have no problem.
I'm disclosing the slow leak-down in the interest of complete honesty in the description; I've run the boat with these on it and there's no operational problem. The leak-down on my friend's boat could even be the trim pump's check valve but we won't know for at least a couple of days to see if the reman'd units have cured it. S
hipping is cheap and fast via tracked Priority Mail so How TF can you go wrong
?
