[iron man]

Here are the new bearings pressed in ready to go!

I then started boring for the cap it will have a mating left hand thread on it with three seals just to be safe.

# I am just about done cutting the taper on the front of the snout. i will also drill a couple holes for a spanner wrench to tighten it up.

 

[iron man]

Seals installed threads fit nice this part is ready to go as well.

I then roughed out a shape for the rear fin.

Here I roughed out a shape for the cavitaion plate mount I changed the shape later to make it look better and to lighten it up.

I have a good friend who has a cnc router that cut me out some nice blocks to hold the parts straight so I can weld them up.

 

[iron man]

All welded up bearing housing installed ready for more.

Again ignore the mess in the back ground here is another shot as to how nice the blocks to align the fin up. The motor will bolt up to the far end with a shaft coupler the mount that hangs down has a hole drilled in it and fastens to the motor mount I made for the boat.

Here I cut threads in a 3/4 X 6' stressproof shaft the left hand grooves are cut to keep crap out of the seals it is suppose to push it out instead of pulling it in.
