I didn't notice any handling changes low speed or high. 
it's inline with the center of the prop, so it shouldn't have any rudder like effects, If you were off center you'd probably get a pull to one side. 

Now I have to pull mine back off to polish it lol

Very Nice!
I did exactly the same thing, stainless mandrel bends are cheap. 
yours is much more complicated than mine because of the wedge but same concept. Looks great!
 

Looks good! 
(other than the weld of course :D) 
I wonder if they make a larger diameter bow roller?

So rotary encoder is working in the code. Now just need to test GPS.
Once everything is up and running effectively I'll put up a wiring diagram. 

Awesome Josh. 

My encoder comes in today along with some jumper wires so I should be able to fully test this afternoon hopefully. 
That encoder looks promising, keep s updated there waterproof is always better on a boat

Okay, so here's the code that works with the new board. 
One oddity is that the polarity of each motor is inverted, I don't know why, not sure if it's a board thing or a programming thing, but retract puts -12V on one output and +12V on the other. This is a bit annoying but very easy to solve, just swap your leads on the lenco or at the relays and all will be well. 

I have not tested the GPS functions or the rotray yes but it should be unchanged from Johns original code, I'll update once I get it put together. 

I'm also working on a bluetooth app, but I'm having to learn all that from scratch so don't hold your breath lol.

I need to give it a go as well, shoot me the code you've got if you get a minute and I'll see if I can come up with anything. 

You ever get anything figured out on this?

I don't know why FAE uses those shitty looking pieced together elbows rather than just buying mandrel bends. Just trying to save money I suppose. They are crappy for flow though. 
In a reasonable quantity mandrel bends are cheap

Stainless tubing isn't bad if you just need 2 bends:

What size are those interior tubes 4"?

No updates here?
I've got a box of parts for the new build and no code lol

Id imagine it will be fine, my internal pipes are fiberglass but they don't get too hot. You could always just replace the hard pipe sections internally with 4" marine exhaust hose if you're worried about it. 

Schedule 40 is pressure rated at 140, the melt temp is much higher. You'll never have any real pressure on the pipe so the 140 is pretty much irrelevant. 
 

Got out on the water this weekend.

WOW sure does make a noise difference. Totally different boat, I can now easily hear the tower speakers while surfing and even talk to people in the boat. 

I noticed a bit of power loss, and I can smell it running rich. Plannning on swapping to EFI this winter so that should fix that. 

No noticeable effect on the wave. 
I'm probably going to open up the transition a bit with some additional tube this winter so it's not a straight 90Degree bend. 
 

Thanks,

I think oval and bigger would have been better but this is what I had so hopefully it works, I'm slightly concerned about the straight 90 and no curvature to the exit, but it seems to work for everyone else lol

I think the ideal would be to do a merge collector instead of the 90 degree exit (like you did on yours, which is awesome by the way) and I may do that at some point if I'm not happy with this one.

The ports are for heater pull out hot tubes. They are not part of the sub box. It is a sealed 1.3 cu ft box with no porting.

Ah that makes a lot more sense! Looks great

Looks great, am I missing something or are the ports not part of the box? They look like they are external to the sub enclosure?

Looks badass! 
How does it ride?

Curious as well, huge thanks for putting all this effort in. 

I'd like to give the bluetooth setup a go if you have the code and a parts list.

Looks great! 
What did it run  to have them do it if you don't mind my asking?

Looks good, great use of space. Do you have a photo from a bit further out so we can see how it all fits in with the interior?
