Installing power trim

[Kissdude]

I have a 1982 50 hp Mercury on my boat, and have just purchased a 1989 70 hp engine that didn't come with a cylinder block but it has a complete PTT installed on it. My question is, can I use this PTT on my 1982 Mercury 50 hp that is on my boat and doesn't have a PTT at all, and how would I go about doing this?
I am very new to this site and any help would be greatly appreciated!

Does the 1989 70hp have the power trim pump that is external to the motor with 4 hoses?
If so, it should work on the 1982.
You'll have to look at both motors and see if the mounting points for the rams are in the same place.

yes it has an external pump that mounts on motor bracket, just has a power wire that controls an electric motor that pushes the rams.

idk, maybe im calling it the wrong thing but it has no hoses

wish I had a way to show pictures of what I have, would explain things a little better.

I believe your 50hp needs the pump that mounts in the boat and connects to the rams with 4 hoses.
What's the serial numbers of the 2 motors?

50 hp is 7174868 and 70hp is 0A743766

Looking at the Part Diagrams, there is NO Compatibility between them

I should be able to make it work somehow, make some holes in my bracket. That top pin should fit top of mine hey?

Sorry wont fit as swivel bracket and clamp bracket ifferent

Two totally different Designs when it comes to the Transom Brackets. the Midsection-Exhaust Housing. As I said, Not Compatible.
But it is Your Motor and Your Money, so you can do whatever you want...

As Jimmbo said, they aren't compatible.
