Works just like advertised
Works great, slows down my old Lund 16' Tiller model fishing boat down where I need it to troll slow for Walleys. Using on a 2007 Merc 4-Stroke tiller model mounted under the Anti-Cavitation plate, and was an easy installation.

Not happy. Now have holes.
I read review after review all over the net, very carefully before purchasing and installing the large happy troller. I wanted to make sure this was right for my boat BEFORE drilling holes in my outdrive. Upon inspection, the unit is well built and snapped closed the way it was designed. I went ahead and drilled holes and mounted.
Without realizing first, I found that the plate was about 1/4" not wide enough to install below the cavitation plate, so I installed above. Instructions says this is ok to do. However, if you have the slightest curvature to your cavitation plate, like mine (Volovo Penta SX drive), the happy troller mount will bend once you tighten the screws. Once this happens, the plate will not go up and down with the spring. It must be forced up and down by hand. For us this was terrible. You just can't reach the happy troller without almost falling out of the boat. You have to do this to put it down and bring it up. Became a total pain. Did it work for us? Yes. Boat did 4.2 mph without it. Slowed it down to about 2.2mph. It also helps the boat get on plane much quicker. If the frame of the happy troller was thicker and it would not have bent I'd give 4 stars.

Fairly easy to install, missing nuts and bolts cost $8.00 more.

Does what I needed it to.
It took me longer to install it as I did it with my boat in the water.
The release cable was too short for my boat (deckboat) and the cable actuall snapped so ir no longet fuctional. I have to use a pole with a hook on it to release the plate.
