Most moern props are very similar so probably is not that important.
The blade area, #of blades and pitch are important considerations. Usually a 4 blade prop is better IF there's not enough blade area w a 3 blade that has a good pitch for your variables. Ideally the pitch should be close to .75 of the diameter numerically. Like 24X18. Most trawlers have big enough props so 3 blade props are best. But if you must get more blade area the 4 blade is the answer .. but only then IMO.
