To spray water down on the top bearing cap is one way of cooling, but remember this. That top bearing cap is 1" thick. It's going to take MASSIVE amounts of water to cool it off enough to provide even the slightest amount of oil temperature drop.
We target the area of the outdrive where most of the heat is generated. By spraying water on that area, we can reduce the oil temperature 65 degrees (if using a Halo Max) and 50-55 degrees (if using a Summit Max Drive Shower. The walls of the outdrive are 1/8" thick. Much easier to cool when walls are thinner. In reference to cost, we have to pay to have these made, we have to buy stainless steel bolts and spacers, boxes, postage etc.
They only fit Mercruiser Alpha and Bravo outdrives.

I've tried a few different types of showers over the years on both performance boats and Formula SS series. Not one of them scrubbed any speed that I could notice, meaning if they did it was less than 1mph. I highly doubt any of them would scrub 2-3 mph.

I tested one on a small light weight boat that responds to everythng +or-. Seriously. Like everything.
No speed decrease.
Now,as I have mentioned before,I ran in to one once with an adjustable pick up height that was mounted with pick up too low,and caused the prop to blow out. That obviously decreased speed. But once it was adjusted so that pick up barely stuck out of cavitation plate, cavitation was gone.
Some other's have run into this with non adjustable pick up, and have had to trim them back.
