Yes I have to agree when I had the smaller prop on it ( 280 ) the boat didn't prop walk as much . But because this boat is still at it's testing stages I want to see what it can handle . The M-6 can handle the big prop no problem and at full throttle the boat is off the water and as soon as I straighten the rudder the boat is like a rocket and very stable . That's what I've been waiting for . Now I just need to control the prop walk which I think I'm almost there . My idea of a drag boat is to stay in your own lane from 0-100 or from start to finish without giving it any rudder . I'll have to get me a 6717-3 from Dasboata and see what happens . Thanks for all your input guys .
Not to change the subject BUT my DaVette SS has the strut mounted right in the center and with a stock 260 Zenoah & a 275 prop it doesn't have prop walk ( at least not that I noticed ) That boat will take anything you throw at it . Very kid proof .
Believe it or not, your runner boat is fine of the current strut position and the rudder blade, I asumed the tracking problem is from your bigger prop, a big prop doesn't mean that will give you a big speed, opposite, it would slow down your boat and bring you lots of trouble, you might also consider a Chris mod round ear cup 2716 15* prop, this prop would run 75 mph on my sprint cat and it'd also run fast for a mono and rigger, once you use a correct prop, the trouble will go away. here's an another method, kick in your tapered blade about 15 degree to the transom side, your runner will track more straight.
