Hey guys!
This is a freshly rebuilt lower gearcase on my Formula.
If you know anything about gear cases and lower units you know that they are not cheap.
So I want to do everything that I can to prolong the life of this one.
Along those same lines I'm going to install a Simrek Halo drive cooler.
You know there are lots of drive showers out there and I settled on this one for different
reasons that I'm not going to get into.
I'm just going to do a quick install and then we will do some on the water testing.
I couldn't find a whole lot of pictures on the internet of what they look like so I just
wanted to show you.
All of the cooling holes are up on the sides here and the back.
The welds look good.
Dual intake tubes.
This Halo fits the Bravo one, two, and three so it's the same for all of those.
We'll get into an install here....
So the installation is very easy.
What you do first is remove these caps on the end of the trim cylinder rams.
You may or may not have caps.
Those come off and then you need a 5/8 and just undo the nuts and then take off the washers.
Then we need to take this upper bolt out.
It requires a 12 point socket.
It's a 3/8 inch.
Most sockets are not 12 point, they're six but you really need a twelve.
Then just take the drive cooler and it comes with a longer bolt, and a sleeve.
Take the bolt, stick it through the bracket on the cooler, through the sleeve, and just
mount the bolt in here.
Just get it started a little bit and no need to crank it down yet.
then you can just gently spread the cooler and stick the brackets over the studs.
This bolt is a 9/16.
Just tighten it down.....
And the instructions say not to put the washers back on.
I believe these tabs will act as a washer.
Just put the nuts back on...
And then, you can put the caps back on.
They may or may not fit.
If they don't fit on there, if they don't thread on fully, you may have to grind the
surface down.
Grind this lip down so they will fit.
But they kind of finish the look off a little bit.
Makes it look a little bit better.
But that's basically it.
I have been told that these come on some of the larger Formulas from the factory and I've
also been told that the Bravo 3 run the hottest.
So hopefully this will keep it cool an keep it living a long time but let me show you
some on the water footage of it cooling.
