Be a little careful with the 94 Nautiques. Most of the 94s came with an Edelbrock derivative TBI one year only injection system that proved to be quite problematic. There are a few cases where they run extremely well but I know of several cases where they never ran well. 1,000RPM is definately too high, should be between around 600RPM as Derek suggested definately not over 800rpm.
Before I bought my 1995 my buddy on the promo team told me to avoid 1994 altogether for this reason. You have already identified a question in this motor so it might be best to move on to other boats. Just my opinion.
