Props...???

[E4NASH]

Well, I think it is time for a new prop here soon. A friend of our's 12 year old wanted to board behind our boat today since their older Centurion doesn't have a ballast system. So we filled up the rear 750s and the bag in the floor for a total of just under 1900 pounds. We also had 5 kids in the boat total weight was probably 375 pounds and we also had 6 adults. It took FOREVER for this boat to get on plane. We've had this problem before when we are Wakesurfing with a pretty full boat. When loaded like this and wakesurfing it has a hard time getting up to the set speed and staying there. I'm pretty sure I need a more torquey prop. I don't care about top end speed. We never really go faster than 30 mph anyway. No need to. The only thing I am concerned about is torque and fuel consumption. What is the best prop that will provide the torque that I need to improve this? I have heard good things about the Acme 1433 and 1847. I think they are both similar except the 1433 is a little better with the fuel consumption and also is better for trailer clearence. I am currently running an Acme 537....

And yes I did put people in the bow and the plate was all the way down and nothing helped. It probably took a good minute before it would plane out.

And FWIW, the kid was EASILY the best rider I have ever pulled behind my boat. 12 years old and he's doing backrolls and all kinds of stuff! I couldn't even begin to try to get booted as high as he was going! I was REALLY impressed! Maybe if I was younger but now, that ain't for this guy! He has been dubbed "Lil Parks"....

1235 if your trailer can handle it. Its a beast, 4k lbs of ballast and no problems out of the hole

How's it on the fuel consumption? Aren't all the trailers built with the same size area for the prop? the only time I have ever damaged a prop was last year with my old boat loading it on the trailer. I'm so paranoid everytime I load the boat now...

You can always shim up the trailer.

I put the 1847 on this year & couldnt be happier... I thought I read on here that the 1235/1433 was the prop for the most torque and the 1847 was good for torque without giving up as much top end speed & burning up as much gas... Where we ride there are some long rides to get to our spots so I picked the 1847... The difference over stock is amazing... We usually run 650 Ibs 1100 surf side 400 locker & 400 off surf & it is a beast... I also slalom ski & the stock prop struggled a bit to pull my 6 5 220 lbs up... Now w the 1847 its up in a second....

The 1433 and the 1847 are the same diameter and same pitch....just the cup is different. I bought the 1847 this year. Now the boat hits 5000rpm, about 40 mph in just few second and get on plane fast with 2000-2500lbs in the boat. With my old prop ( 14x1 is was hard to plane with just 1200lbs. for surfing with 2600-3000lbs the boat hold is speed easly.So my boat is now almost as fast as before ( I should check with a GPS), but pull a lot more........

I have the 1847. Same diameter and pitch as 1433 but extra cup, means a little less top end loss.

Big E - lots on here have moved from the 1433 to the 1847 due to the growl on the 1433 some have experienced (if I recall correctly but a little PWI at th e moment).

I had a heavy load of both people and ballast on my stock prop last year similar to what you are describing and it was a little embarrassing how long it took to get up to speed. Like you said, 30 seconds to a minute. This year first run with the 1847 I had about 2800lbs ballast and 5 peeps to test my freshly installed 1847. Got up on a plane in maybe 5-10 seconds I'd guess. That was impressive. I don't know if I'd call it night and day difference based on my limited experience so far but it definitely did the trick.

I'm liking what I'm hearing! I really appreciate the feedback fellas...thanks!
