Alot of the early reports (1996 thru 99) of hot foot throttles on the newer digital injected outboards (opti, Ficht, HPDI) were that they were not approved by the manufacturer because of lack of test time by them. There were even reprots that you would void your warranty if used. This is untrue, at least from my sources. There were problems with the speed of travel on them in reagards to throttle position sensors (TPI or TPS) and that has since been worked out by the motor manufacturers. Some adjusted the TPI units others added or subtracted additional units or replaced them with newer technology. You should not have to worry about "blowing" your motor with a foot throttle. Unless you have changed out your ECM (electronic control module) you should have a rev limiter and that will help protect the motor in the case that your prop has left the water momentarily. I must warn you though the more you do that and the worse it looks on your ECM to the manufacturer. I do not suggest hammering your foot to the floor at all times even while airborn because the more time you have hitting the rev limiter and over recommended max RPM, the less likely the manufacturer will cover motor failure.
