Thanks Ray.
This was only $5 for 2 of them, nicely done at one of the shops here in Mississauga on Cawthra Rd south of Dundas.
I like it and I hope it will make a difference ( it's like I know how she was before the mod )
I also have all the props people are suggesting here to try S&B&P.
Now I need H2O not the Ice....

Nice job!- I am concerned that you will discover what I and others have with that configuration. My first installation was witht the Kintec Racing bracket which basically the same shape as you bracket. Looked great and installed in seconds. The only issue was that the lower half of the bracket created drag and a very large rooster tail, until my boat was at full throttle.
I tried the two Octura spacers which worked equally well but still kicked up a spray and created some drag.
I contacted Kintec and shaded this with him, and from that conversation, he created his 2nd version of his bracket which has the lower half machined out.

It works perfectly. The pictures below show the area that was removed to eliminate the drag and rooster tail it created.

I see...
Need to do few tests and if that is the case I will cut my second bracket to eliminate the drag and install....
Current bracket buttom edge is a little higher than buttom of the hull so hopefully with the spped increase when boat will start getting in plane this will be no issue...

I don't get it. If you really wanted to move your rubber over wouldn't it be easier, and more effective, to mount an "L" bracket just to the right of the servo arm, on the transom of the boat? I'm new to this boating stuff but that would seem the most logical to me.

[LiPo Power]

Installing it there is no problem but you would need to first install reinforcement inside of it to make sure it is strong enough. Out of the box this area it's just fiberglass hull thickness....
Someone did this here exactly the way you are describing with a little more work.
Check picture...

If you adjusting your strut to be even with the bottom of the ride pads make sure your prop has enough room to spin.
I have done some try outs here with X642, M445, Prather 430 and there is no way to spin them if the strut is even with riding pads....
I will need to grind the corner of the mount off a little to use this props.....

Robert, that's my boat you referenced in post #171. I have only run it a few times since the mod but seems like a winner so far. You are correct about support, I used a pc. of marine ply to hold the t-nuts in place and add strunth.

[LiPo Power]

So what prop are you using now?
Is your strut level with riding pods?

Strut level and last setup was cc1512 1800kv on 4s and prop was x447. Bounce was gone but ran in slight chop.

[LiPo Power]

Does your X447 have enough room to spin with strut at level with riding pods?
Coul you please post close up picture of it?

[blackcat26]

Picture is kinda blurry but you get the idea.

[LiPo Power]

I see now.... Great idea!
Well, since I have used the other option to offset the rudder here is what I did to be able to fit other props...
Robert

[JackBlack26]

I figured structural support back there to mount the rudder would be necessary but didn't understand why it would be an issue. I would use a piece of like a piece of .032 or .064 aluminum. I hate wood in these boats.

Blackcat26, now that looks awesome! Looks very clean. What bracket did you use?

I have a 1512 1800 and a Castle 3424 1800 outrunner. IMO, the 1512 is too big for the boat. I ran multiple runs with the outrunner and my batteries didn't heat up over 89*. I installed the 1512 and it killed the same batteries, cheap HK 5Kmah 20C LiPos, I ran the outrunner with. They came off at 130* with the 1512 and now kick the ESC in to LVC in just a couple of minutes. I'm sure you probably have better quality batteries though. I don't have a Data logger but it seems logical by this experience that the outrunner, generating more torque by design, draws less amperage, runs everything cooler, and provided longer run times......Just my thoughts.

are the speeds about the same between the two motors?
