Like a kid waiting for Christmas, I've been checking the backorder status of the 24v 45" Ultrex Link I have on order at Tackle Warehouse since January. I just checked a little while ago and the backorder on my TM was moved back again from 3/11 to 4/9. I called TW to see about getting a refund on the gift card I bought it with. He said they would give me the refund, no problem. Then I asked if they had a 52" in stock and sure enough they do....$54 more on the cc and the Ultrex will ship out tomorrow should receive the end of next week.
Not sure what complications are involved with getting the longer shaft as far as mounting goes. Also I'm sure the cover will be a problem but it would be a problem with the 45" shaft as well.
