‘03 232BR 350 MAG/Bravo 3
i know we have a couple other 232 owners here. You guys running the 350 MAG, what prop pitch do you have? Mine has 28s on, and I feel that seems a bit high?
Let me say that we slalom ski, and pull everything imaginable behind it, and it gets out of the hole okay. I slalomed behind it last year at 220 lbs on a 66.5” competition ski that drags a lot of water, so it obviously does okay, but peak RPM at WOT should be 4600-5000 RPMS, and I’m only getting a little over 4200. We had half a tank of gas, 2 adults, and 3 kids on it today when I ran it out to see what it would turn. Trimmed up to max speed, this is what it was doing. Top end seems a little down on the 350 MAG too.
So, if I pitched it down to achieve closer to 5000 RPMS, obviously it would plane out a little quicker, but would my top end go up or down? It’ll turn more RPMS, but be pitched lower, so are those two things a wash? Since it pulls hard enough, would it be better to just leave it alone? Thoughts?

I have a 2004 232 Captiva BR with 350 MAg and B3 drive. It came with 26p props. It ran about 4500-4600 rpm with 4 adults. I usually have 5 - 8 adults on board. Last year I bought 24 p props and it did improve getting skiers up and still ran about 4800 rpm.
I had a wild hair this spring after reading about Hill Marine 4 x 4 props so I bought them in 24p. They work great for me with 5 - 8 adults pulling skiers or 4 person tube (also adult kids). I am still under 5000 rpm WOT with 4 adults and 1/4 tank fuel and hit 46 mph on GPS.
Speeds not my goal though. Needed to base props on what I want to use the boat for. I have the original 26p props and the 24p props I bought last year. Make you a deal on either set or both sets. PM me if interested. Both sets are like new.
speed isn't my goal either. I've had this boat for 8 years and am just now getting around to checking to see how many RPMs it turns. Lol. I usually cruise around at ~35 mph and we do a lot of skiing/tubing, ect... I have had 11 in the boat and 1 on the tube before, and the boat still did fine. But, I just don't see 28P props much, so I'm wondering if 26s or 24s would make my boat better for what we do. My typical load is 4-6 people.
