Google Ai tells me the 1978 Mercury 70hp didn't have a Power Trim option. But I'm reading that it came on later models.
.
Does anyone know if there are newer models that have Power Tilt Trim that can be modified to work with a 1978? I know I can buy a CMC, but I was wondering if there are power tilt trim from newer models that can work.

Once again AI may be wrong.----Pretty sure power trim was an option in 78

Okay, so Ai is an idiot!
Are there later models that I can harvest power trim tilt?

I'm reading that finding a balanced fixed setting is good enough.

I think you need a PTT unit from the 3 cylinder Mercs starting in the early 70s. I think you can also use one from the 4 cylinder 50HP Merc of the same vintage. I do not think the PTT unit from the 4cyl 800 or 850 or any IL6 will fit. The PTT system consists of 2 PTT brackets, PTT pump/reservoir, 2 PTT cylinders and 4 hydraulic.

One or more of the members on this forum have such a system on their motors and have provided pictures in the past. Hopefully that will do so again.

There are also aftermarket systems like CMC.

Check out the 3-cylinder 50 and 60Hp from mid 80.es.
I think from 1985 (red-black-brown decals on the hood) and up, PTT from those might fit.

The 3 cylinder 65 HP beginning in 1972 had the trim / tilt unit that will fit the 70 HP models.

i have an 82 50hp and the two rams are on the sides so i would think it would fit but not sure.

I am sure that the cost of finding an operable used one is about the same as a new CMC off amazon....
