    Default Weight to Horsepower

    I'm sure this has been studied before, but is there any kind of measure on how much horsepower is robbed by each pound in a jetboat.

    this is something we have been testing for years and the variables are endless.what we have come up with on an average only is 40 to50 lbs = 1 mph that is a very short answer that could fill 10 pages on the forums.. we have tested a lot of different boats and that is the average we have come up with..

    40 TO 50 lbs seems to be about right for a 1 mph gain but more importantly the quickness is where you will see a big difference. In a drag boat race we are able to see what our 1/2 tracks times are and by putting the boat on a diet and say loose 70 to 80 lbs we will see approx. 2/10ths of a difference in our half track times. To pick up a 2/10ths advantage on your competiton is a ton.
