Old thread but I have a similar question about adding trim tabs to my 2017 Crestliner Fishhawk 1850 WT with a 150 Merc Pro XS and kicker. I fish big water a lot and have tried a half dozen props to get my boat to plane faster and at lower speeds. I find myself want to go below 15 mph a lot and am constantly on the throttle adjusting the speed to try to keep the boat slow, but on plane. Started with a 3 blade aluminum 21p, but just went from a 4 blade Revolution 15p to a 3 blade Enertia. Probably the best so far, but still struggling. Think these would help?

Any other suggestions?
I see they have them to the far outside edge so it must not be a problem at higher speed and trim. Probably a combination of livewell, kicker, and prop roll all to the same side at lower speeds and trim. usually just a small amount of upwards trim helps a lot as well.
