2006 130 SPORT with new Mecury 40-HP

[MODERATOR's NOTE: This topic moved to PERFORMANCE because it seeks to discuss the performance of a Boston Whaler boat.]
I have a 2006 130 Sport that I re-powered at the beginning of the 2020 season with a Mercury 40-HP FOURSTROKE manufactured in 2020. The engine is mounted [sounds like two-holes up--please use the "holes-up" method to describe engine mounting height. See the pinned article at the top of the PERFORMANCE forum to learn the basic description method for engine mounting height--moderator]
The propeller is a Mercury aluminum BLACK MAX three-bladed propeller with 10.5 x 13-pitch--it is the old propeller from my 2006 engine that is in good condition. I reused it.
With a light load [the 130 SPORT boat] jumps up on plan. [The new Mercury 40 FOURSTROKE engine accelerates to] close to 6000-RPM, and the boat speed is around 30-MPH.
Top speed is not my main interest because local wave conditions don't allow high speed runs often.
I frequently run the [130 SPORT] with a heavy load. I would like to reduce planing time [when there is a heavy load] and have a better [acceleration onto plane from a standing start when there is a heavy load].
Q1: Would a four-blade prop provide more stern lift?
Q2: Would a four-blade propeller help the boat get on plane with a load?
I'm not sure of the propeller pitch for this scenario.
I've also thought about a hydrofoil type device but I'd rather try to maximize propeller first.
