...Good reason to buy your Hobie from OEX!

REMEMBER guys TONY is Hobies stress tester, he is HARD on drives and other equiptment. Great job on the repair Tony. NOW go molest some moore BUTT.

Great job. One thing I have started doing is when I have to remove broken bolts is use a left hand drill bit. Most of the time it will remove the broken bolt or at least not tighten it up more.

Now go catch some more fish!!!

Unless they are less grade of SS.

Regardless, good job on repairs.

Def not a lesser grade stainless
The mast are made with Ph 17-4 SS which is heat treatable and is magnetic
The mast are much stiffer than 303, 304 or 316 SS of the same size.
As others have already said. Slow RPM with lots of pressure and cutting oil

Hobie probably thought that jumping up to .312 instead of .281 would eliminate the chance of breaking a fin mast

Good job on keeping the drill centered
I used a vice and a vertical mill to remove a broken one on a V2 drive last year

In our shop, we have better luck using square drive extractors instead of the spiral type


Tools used

After I broke a mast fin, ful-rac pointed out that it probably broke due to corrosion.
After close examination, shureasshit he was right
This drive was 3 yrs. old at the time. If you notice, the corrosion extends deep into the fracture. And yes, I do rinse everything off after every trip


This was the other mast that hasn't broken yet




Keep an eye on your masts on the drives that have been used in the salt for a few years

Anybody else not seeing my pictures?
Using photobucket as the host

Photobucket is now a paid service and if you don't pay you can't use your photos on 3rd party websites. So upload your pictures to BWE instead.
