Yes but you have only three options.
1) get more horsepower
2) variable pitch prop
3) reduce drag and or weight

900 rpm is quite a lot. The larger the diameter of the prop combined with the right pitch is the ticket laddy for bottom end pulling power. Start with the largest dia. available for your engine and go from there. If you need help, add to your question.......Need a slip calculation on current prop!

You didnt say if it was a 2 stroke or 4 stroke - If this is a 2 stroke - you need to be careful propping you engine off its peak horsepower curve - you risk blowing up the engine through detonation. Get the engines maintenance manual & look at the horsepower curves - they are listed in the first chapter under "engine break in ". If it is a 4 stroke - where you set you pulling RPM depends on your camshaft specs & intake & exhaust efficiency - if it has been modified.

nope. just watch the tach and don't over-rev.
