Hey
I have a 2000 model OX 66 (SX150TXRY) and have a problem with rpm loss. This occurs after about 10 minutes when the motor is good and warm. The rpm loss is sudden and occurs without warning. It does not completly shut down but instead seems to drop back to 3 cylinders. Just as suddenly as it drops off, it starts up again. The suddenness of the problem makes me think it is electrical. I got a switch and wiring harness from a local shop and bypassed mine but I still have the problem. One thing that I think may be significant is that whether I use my ignition switch or the replacement, I am not getting awarning buzzer at start-up. Once it starts this mess it will continue until after it cools off.
I have replaced the fuel/water separater and the inline filter because at first I thought it was a fuel issue. I took it to a local marina and they ran it on the water twice but it ran okay for them so $250 and 20 gal of fuel later they have no clue what is wrong. It is expensive to test it will not miss a beat at idle or low rpms so it has to be run on open water.
Any advice would be much apprecited.
