Re: Props
Just to add, 3500 rpm may be just on plane for that boat.
FWIW.....The above is just my opinion.

Re: Props
You should be able to find the specs for your engine if you know the model and the year. A bit searching on the Internet should find plenty of reliable OEM sources. The operator's manual or service manual should have that info too.
There's not a huge difference in the 3 blade vs 4 blade, so long as each are sized appropriate for the powertrain and hull.
My boat was spec'd for 4 blade props, but I found a set of 3 blade props that were very close and I used them as spares a couple times when I dinged my original props. Each time ran them for about a half season before I switched back the the originals when the boat was pulled at the end of the season. I could hardly detect the difference in how the boat ran or handled, except the RPMs were about 200 higher at cruise.
