Tweetanybody have a boat, any kind fishing runabout or jet? I love my toys and there is nothing like cruising at 70 MPH across the water. I have a 19' champion hull with a 2.5 merc on the back. the fastest I have ever been is 75mph with 3 deep cell batteries and 30 gallons of fuel. not bad for a bass boat. I have 300 usable rpm left but it just won't go any faster I have a 27" tempest prop I am going to have tricked out by mcgill prop hopefully I can get 78mph with a good holeshot. I want a donzai too but cant afford it with all my other stuff.
