At Tuffboat.com I have seen Hondas and Yamaha 50 with jet drive. I guess there is some kind of conversion kit to replace the lower unit. <br />Is it?<br />Any idea how much $$$?<br />Do the dealers have them or is i an american manufacturer?<br /> <br />For the same performance (speed) you need about 30 percent more horsepower with jet drive, right? <br /><br />Is there anyone here who have done this conversion? And, if so, how did it effect performance, fuel consumption...?<br /><br />Any reply is appreciated. Thanks. <br /><br />/Bear
