I have not been near a real race boat in years, but a friend told me about Jet Sprint Boat Racing.
It started in New Zealand.
He attended an event in Richland Washington.
Looks pretty cool and might even get me out of retirement!
The courses are dug canals and only cover a few acres of land. The water is only a couple of feet deep and a track can be put in away from a large body of water.
X it out and let me know what you think!
It uses small block chevies and reminds me of a water based Super Modified stock car race.
