Thanks for all of the input everybody.  I've placed my order for the FAE tonight.  Contacted the dealer about the "factory" MB surf pipe, but it is considerably more expensive and it seems like the FAE is a proven product.  Can't wait to get it on!

I had 2017 440 engine B52 23 with no FAE/Surf pipe. Just picked up our 2018 575 with Surf Pipe and it is significantly quieter. Not sure how to measure the engine change going to the new 575 compared to having the surf pipe now. RPM’S are way lower with the 575 compared to the 440. If anyone is thinking on weather or not to add on a new build my opinion its a must have. If I had the 2017 still I would have been adding that now while the days are still cold.

What prop did you go with for the elevation and what surf rpms are you turning? I believe the tranny is different in those with 575 compared to the smaller motors.

Prop on my 2017 b52 440 was a 2775 the new 2018 575 also came with the 2775 on it. Dealer has us going to the 2701. 15.5 pitch. Going out this Saturday fingers crossed. Snowing today. I will pay more attention on exact rpm’s while surfing.

kind of strange they would recommend a smaller diameter prop? 

 

Iv'e been looking into the 2247, same diameter just a 14.25 pitch, I too have the 2775 prop 12.5 pitch

I installed a FAE on our 16 B52 with a 400, it is much quieter. The wave isn't affected at all.Posted Image

The 575 motor has a 1.5:1 ratio. Mine came with a 2475 prop. runs 3k at 10.8 fully loaded. Looking into something bigger to bring down rpm even more

With as much power as you have, I wouldn’t hesitate in the slightest to run a 2277. I run the 2279 which is same diameter and pitch but less cup on my 400 and it works great.

thats what i would think, especially at sea level. 

 

but super charged engines like some rpm's in there so you wouldn't want to be too low

I missed the part about the difference in trans ratio. So yeah a 2277 will put more load on the engine and drive lower rpm than it does on my 400, but I would be shocked if it was too much.
