Bill, I meant the Boca Ultra-Seal Ceramics! The Boca rep said they were better than the orange seal, so am curious if you have tried them.

Sorry bud, I haven't tried those yet, but I DO recommend rubber shielded bearings for marine apps even the fishing guys stay with rubber

I bet they fly though from what I've heard..

Since I run in salt water, I wanted to make sure I had a good sealed bearing. The ultra seal bearings are steel over rubber and supposed to have a much "better" seal if you can imagine. I've heard nothing but good about Boca Bearings! =)

Sounds about right!

Regardless, with this much power and high CG, the boat will handle like *!***!***!***!**. I've been running mine on 5S with 540's and flipped it numerous times, even with the CG as low as I could get it. This boat is basically only good for SAW runs after any amount of extra weight has been added..

Strut removal

Ok boys we're gonna' start this strut upgrade and first we will remove the strut from the transom..

figure 2 shows how the transom looks with the strut removed.

The strut is a nice CNC machined unit of high quality.

Bearing Removal

Ok fellas, now we've gotta' remove these bearings. When recessed in aluminum, I like to heat whatever the bearings are pressed in for easu removal.

I prefer to use a soldering iron for this procedure.

Press

Next we want to press the bearings out. using a large diameter diver, I press the bearings out from the inside starting with the rear output bearing then the front.

Using a large diameter driver assures you don't damage the bearings in the process..

Spacer

Now that I've got the bearings out, I noticed this teflon spacer.
A trip to Franciscan hobbies in the morning will yield us a piece of brass tubing for a pro setup.. See you cats manyana..

Clean work

Before installing anything, I first sprayed out any existing grease with electric motor spray

[BILL OXIDEAN]

Heavy metal!

Stemming from being an 80's heavy metaller I prefer metal spacers

I went ahead and picked up some K&S aluminum tubing stock#104 3/16x.014

With my tubing cutter I cut and de-burred 2 7/8 inch pieces after measuring the distance between the bearings front and rear.

Re-Install

Ok, now its time to press the bearings.
Starting with the front bearing, using a large diameter philips screwdriver, I pressed the bearing in.

Next I inserted the spacer, then pressed the rear bearing in and voilla! You've got an Oxidean style Boca Bearing upgraded strut!

viola

Did you cross drill any holes in the spacer tube? I've seen that before, not sure of the purpose other than to help with lubrication of the hard prop shaft.

Curious to hear a racer's take on it.

In the old days when guys made scratch built struts, they used a piece of brass tubing as part of a bushing. The grooves reduced friction, but My method is well lubed and the spacer is frictionless. It spins with the rotating assembly.

Good question!

[forescott]

Is the spacer really necessary? I took mine out when one of the bearings came loose. I didnt see how it really did anything.
