Continuity mistake: While Scott and Tom are working on the boat's engine, and then while Dianne is with Scott, there's a boat near them with registration number "F 0258 ML" at its side. When Scott is alone after Dianne leaves, the boat's registration number is now "CF 0258 ML" at its side. (00:52:35 - 00:57:10)
Continuity mistake: Near the end of the race, Scott is wearing gloves as he gets Rawhide's speed up to match JJ's Scarlet Lady. When the announcer says, "Remember, that's the hull that split apart last year under even less strain," in the shots of Rawhide's hull as it's porpoising, we can see the driver is not wearing gloves, and the windshield differs as well. (01:30:55)
Other mistake: At Marine Stadium, in the shots facing Sam and Duster together, particularly before the race begins when they mention Goop, note the blonde-haired boy seated two rows behind them. This boy repeatedly lifts his hotdog to his face and amusingly pretends to take bites and chew, all the while his hotdog remains whole the entire time. (01:23:25)
Continuity mistake: During the Orange Bowl race, "Tom Wilson," aka Scott, is the driver of Rawhide, number 99, and he's wearing a long-sleeved red jacket. However, when the announcer says, "There goes the Rawhide, Tom Wilson is really standing on it," in the long shot of Rawhide, number 99, the driver is wearing a short-sleeved red shirt (it's not JJ, who is driving Scarlet Lady, number D3). This occurs a few more times in long shots during the race. (01:28:10 - 01:32:05)
Continuity mistake: At the end, when Dianne's "taxi" shows up, Scott and Dianne go for a drive in Scott's car. The rearview mirror is gone in their close-ups, but it's back in its proper place mounted between the windshields in wide shots. (01:35:35)
Continuity mistake: When Scott tells Dianne the truth about everything, Dianne's wearing white opaque nail polish, but when Scott gives Dianne his driver license, in the close-up the fingernails have clear nail polish. (01:36:20 - 01:38:05)
Continuity mistake: When Dianne and Scott (as Tom, the water-ski instructor) head out on the second water skiing session, in the long shots of the boat, its windshield's center walk-through is open, but in the close-ups of Scott, the windshield's center walk-through is closed, then it continues to go back and forth. (00:29:30)
Revealing mistake: After Scott and Tom switch places, during the drive down to the hotel, in some close-ups there's black tape covering the motorcycle's chrome trim. (00:06:35 - 00:07:10)
