54" Bonzi Fountain build

[Rumdog]

You're probably going to want to extend the rudder bracket to get the rudder behind the props.

I hope turning won't be an issue. Those keels on the stingers are gonna want to keep the hull going straight.

I was thinking about that, but there must be some reason MTC builds them like that.

Not sure why, my big gas boat is set up just like this except it has one drive instead of two. The rudder is off center and in front of the prop and the boat handles fine.

I was playing with the drives and I may be able to make them steerable. I'm still looking into that so maybe I can eliminate the rudder all together.

Skegs will act like turn fins.

Thats what I was thinking as well.

Not mounting them yet though, I want to see what those 820 outdrives look like. If I end up not using them on this project I'm sure I will on a future build.

Whats a good set of props to start with? They will be counter rotating. Would these be to much prop? Not sure what diameter to start with.

Just got the drives and rudder from MHZ. I must say these are some nice drives. I also got some trim tabs from MHZ but I found these from Redline, they match the drives very nice so I'll use them.

Here is a transom mock up. The hull will be black so this gives an idea of how it will look.

Yeah, I think skegs would act like turn fins, as long as the rudder isn't right between them. Is the rudder much behind the skegs or are they side by side?

Drives look good man.

Chris,

I would say these props are a little big to start out with.

How about something around 55mm dia 3 blade counter rotating props.
This would be a great starting point to check your amp draw and temps and then work your way up.
You will find that you will keep those motors in the right torque curve plus won't pull too many amps = Run time and still give you a great turn of speed.

Yeah I thought those 6717 props would be a little big. Problem is I want counter rotating 3 blade stainless steel props and they are hard to find.

Any good sources for props??

Mate they have stainless steel 3,4 and 5 blade props counter rotating.

If you have trouble finding them let me know and I will post a link.

I found them pretty easy and they do seem to have a lot of props. But no pictures. Being that I don't always know what the numbers mean the pictures help.

Plus I like to see what they look like.

I will head on over to them now and give you some details.

LOL...really? I guess you're right down the street.

Here ya go.

Cleaver style,

CRC / 5517/3/LH/SS
CRC / 5517/3/RH/SS

Means - 55mm dia, 1.7 pitch 3 blade, left hand rotation, stainless steel
and the other one is right hand rotation.

Just ordered those exact props. I guess I made a good guess. Though I knew what those numbers meant. Some props have some completely different identifying numbers.
