I helped my little brother pick up his first jet boat this past Saturday and took it out on it's maiden voyage (under it's new owner) on Sunday at Modesto Reservoir.
The boat is a nice little 79' Nordic Bubble Deck with what seems to be a stock 454, Air Gap intake and HEI, vacume secondary Holley (750?), stock Dominator pump, and over transom logs. With me driving (245 lbs or so) and 15 gallons of gas, it went the best of 62.9 MPH in choppy conditions, which we are pretty happy with considering the reasonable price we paid.
Without going into the motor, I am fairly positive that we could gain the 7.1-8 MPH (hopefully on the conservative side) we are looking for in search of 70 MPH with just the following...
Hopefully we can find all the parts we need used to stay in my little brother's budget
- 2 or 4 degree wedge
- Bassett or Rewarder Headers
- Place Diverter (or not)
What do you experienced folks think? Possible?
