Knowing that there has been a problem with the lower unit pump flanges breaking, I approached a machinist friend of mine and had him make up some better flanges out of billet 6061-t6 instead of using the stock cast units. I already had a 4 bolt unit on mine but I replaced it anyway. He also made a 2 bolt version for Ernie. And Ernie even had him add some additional thickness to the bases of those units. If you are coming to Bensen Days, you can see a 2 bolt version installed on Mike Boyette's Dominator and a 4 bolt version on my Dominator tandem. You can get them from my friend Brad for $50. His number is 2 BOLT FLANGE.JPG

Nice! I switched from the two bolt to 4 bolt and got better life out of the flange. Machined would be much stronger

Brad is makin these for 50 bucks. Not these particular ones. He wouldn't make just two, so I had to make my own.
He does a nice job for a good price.
I would have to charge 200 bucks for the same thing, gotta love a CNC :)
Can't blame him, setin up for two ain't worth it.
Now to decide four hole or two hole flange

I've asked Brad to make a run of six or so two-bolt flanges as soon as he has time. Please post here if you will want one. That way if we need more than six, you can all get them on this run and not have to wait.

Update on the flanges!
Brad Kapper finally called me and said that he finished making a run of hydraulic pump flanges that fit Ernie's lower unit pumps. He has sixteen of the 2 bolt flanges and four of the 4 bolt flanges on the shelf. His number is 941 720-0782.
