I had to replace the prop for my Vector SR80 pro after hitting some rocks when the boat left my sight. the prop was a perfect fit. And about the SR80 pro boat, it's one of my favorites. I have the vector 01 smaller model and I also have 3 different Horizon pro boats that two goes 55 mph plus and one 50 mph plus. I would put the Vector SR80 pro up against any of my 3 pro boats as far as reliability and actually surpasses one as far as durability and matches the other two in durability. my vector 80 pro took a direct hit at around 23-25 mph into an aluminum paddle boat and was pinned into the paddle bars and only sustained a split or open crack at the very top of the boat of about a quarter inch. JB plastic bonder fixed it right up and still leak proof. I sustained 5 spider fractures in a Horizon pro boat after only flipping the boat on water traveling at around 50 mph which needed a whole new boat hull but managed to JB plastic bond it requiring a whole tub to put it water proof again but it doesn't look very attractive now and that boat cost ***** and had inside done in fiberglass.So the Vector pro 80, I would put up against any boat in its class and bigger for value, performance and durability. I have put it through very choppy water and flipping it 3 complete 360 end over end flips before it even hit the water again with no damage except the lip on the nose of the covers snapping off which I fixed easily with a small piece of aluminum cut and tightened up under exis

Yes it is the same prop. but don't buy the boat it is a piece of crap. my hull split just breaking in 3s batteries 2 in parallel doing tight turns changing direction. a couple of weeks later the esc blew up on 4s this time then the servo quit out in the middle of the lake. all within the first 2 months of owning it. the company basically told me to pound salt its my problem now.
