Dave, I destroyed 3 (maybe 4, I can't remember now???) IMCO Extreme XR units (I try and block all the tows back to the marinas out). I was not overly impressed with the service I was given through IMCO. They did replace the units at a reduced price, but that was still expensive. I do not want something for nothing, but the total hours on the 3 units was about 15 hours (one had less than 2 hours on it). I talked to Bob Teague and he offered a 90 day warranty on his Platinum XR drive and I went with that. I boated all summer and the unit still is working well(approx. 40hrs.). If the unit blows up now, I am at least ahead of the game I was playing before. I don't know wether I just received units from IMCO that had flaws due to gear hardening(this was a problem I heard). I know others who have had good luck with the IMCO units, I was just rather tired of being pulled back to the marinas, and decided to try something else. The warranty sold me on the Teague unit, and Bob was very sincere in his willingness to help.
