As I'm old, and "mess around" with old outboards, different ones, I ended up springing for a CMC 130hp rated tilt/ trim unit. I am NOT IMPRESSED for a number of reasons
1..."Let's say" that you have any bolt on outboard pretty much properly installed on your boat. When you install the CMC, you have to jack the outboard up a ways to get things to sit as they were without the tilt/ trim
2...If you want to use a clamp on engine, and I USE BOTH occasionally, you either must build, or buy from them for nearly 100 more dollars, an adapter. This jacks the clamp on outboard up ?? about 2" or so, so that in my case I had to re-drill the tilt unit and drop it down to "come out" the same. Part of the reason for this, is that the actuator mounting is in the road of clamps unless raised!!!
3...Also the actuator seems to me to be reversed. Instead of pushing against the bottom of the tilting part, and the upper end against the transom, which would seem to be better leverage, it is angled opposite. I 'played' with this and evidently the oil pickup in the reservoir is such that it will not pull oil when mounted at the other angle. That is, as the thing tilts, the angle changes, leaving it sucking air.
In my opinion, this thing is fairly poorly designed. I actually picked up a couple of tilt units off junk outboards and an seriously thinking of "trying it myself."
This item by the way, is about a grand U.S. dollars
