Keith,
We typically run our 1990 34 with the same engine and a 3 blade max prop at 2400 cruising speed. More importantly, you need to check to see if you can reach max rpm to determine if you are over/under pitched. Check the plate on front of engine to verify max rpm and see if you can hit that at the dock in neutral after engine is warmed up. Then take it out in flat water and check to see what you can do with throttle wide open. Assuming a clean bottom, you should be able to get close to max. If so, your prop pitch is good.
