Looks like a nice Ultra. No complaints with their product.
The trailer under a boat is often overlooked. Mine came with a disc braked 02 or 04 Extreme trailer with a chrome swing tongue... That was a strong selling point to me.
Edit: I just looked up the ad, I'd make an offer on that if I didn't have mine. I paid 10 for mine, somehow I racked up 4k in re doing the interior and stereo, 1300 to have jet rebuillt with a new shaft, 400 on droop and ride plate... and I don't have a fresh 502 with headers... I have to keep a future motor in my budget (hopefully not for a long time, its a good runnin marine power 454)
That's probably close to a 65 mph 21'
