Scarab Racing Boats Knowledge Base
Scarab, Fountain, Racing, MPH, TOM TOM, boating, offshore speed? I took my boat out today and it said i was only doing 65. i own a 28 foot scarab. it has a big block, super chiller and a B&M 250 blower. All in all it is making at least 750hp. my friend brought out his tom tom to see how fast my boat would go. we were all guessing mid 80's. but then we were greatly let down by the 65 mark. I was wondering if the fact that this is meant for cars could be the problem. Does anyone have any info? Ive been into powerboating and dragboats for about 37 years. Im not one to over exagerate like most do at the local lake and rivers. My scarab is 28 ft and weights 4300 lbs. It has a 502 with a superchiller and blower making 750+ hp. the conditions were some what rough. i was airing it out. the big factor and i dont know how much it weights in but it was 110 degrees out and the water was really warm. My biggest disapointmen is that i read write ups in hot boat and powerboating magazine that show the exact same size boat with a even weaker motor that is running in the mid 80's. and believe me ive had flat bottoms and top alcohol hydros that ran 7's @ 156 mph in the quearter so i have a prety good grasp on speed. The only thing that i can think is either the TOM TOM is not very acurate when in rough water on a boat because its not ment for marine. or the conditions were killing my boat.
