Thats what I thought so why is he pulling the motors?

I may be wrong, but I think that the backing plate of the standoff box on the Arneson Drive that is inside the engine room and Transmission serve as the rear engine mount when put together. I read the instructions Rik gave me on how to install the ASD7M, and I think that is the way it is set up. There were no pictures as I hoped, so I am a little confused on how to install the drive myself. I may be wrong. At least I hope I am.... Maybe Rik will join this conversation and clarify it.

No the notch was not an issue.
Installed the drives and engines and bolted everything together. The mounts were 3" apart. They only thing to do was to slide the engines forward.

The transmission is mostly in the bilge and is flush with the exterior portion of the transom. When you take off the access panel that is on the standoff box, you can see the front of the transmission at the transom and the drive shaft.

You are correct and as previously stated, every boat is different, and on some boats you might not have to move the mounts.

Do you think you will have your boat in the water for Labor Day for test number TWO?

If everything goes as planned, I'm hoping for this Thursday.

Good Luck. Don't forget your GoPro. I am curious how hard it is to get on plane. I bet it is going to be tricky, but you should figure it out. Personally, I would try getting on plane with tabs and drives all the way down, then slowly raise the tabs after you gain some speed. That is what I had to do when I had blowouts with clever style hydromotive 4 blade props on a bravo drive, 12,500lb 38 foot Cigarette Top Gun. It allowed me to get on plane and keep the RPM's under 3000 when my engines where still a little cold. Just an idea!

Good luck with it tomorrow. Looking forward to hear and see how it works out.

:food-smiley-007:

kjm5125. Have you had any time to get the tranny fixed and the boat in the water?

Yes
 

I had time for a run Saturday, (Sunday prior commitment and Monday crappy weather)
and the main issue was how to get the boat on plane. Arneson surface drives are very different compared to my Bravo Xr's / Shorties. What you need to do is keep the tabs down and stay on the throttles until the boat starts to plane and then she blasts off. Every adjustment you make with the drives and tabs is highly accentuated when compared to the XR's. I definitely need some seat time to fully understand the handling characteristics.

Next time out pictures and or video.

Sounds like things are moving in the right direction. What is the rake on the props?

How is the handling when on plane and at the docks?

Looing forward to hear some numbers.

Congratz on your first succesful outing.

VIDEO!!! If I remember, you are trying 5 blade 17" Diameter 31 Pitch Props. Can't wait to see what RPM you are running at WOT......also speed.

Rake is 18 degrees

Handling will not be a problem. The line does need to be bled. I'm going to add another pump and reservoir.

Performance numbers to come.

At 4500 rpm's the ROOSTER was pretty amazing. I was not paying that much to speed, as I was concentrating on trim and tab setting.

How would an Arenson work in a single drive v?

Give Rik @ Arneson a shout. He can tell you the pros and cons of your particular installation. He's also on the board.

Well, when is your next run. We are waiting on pictures and video....:boat: Can't wait...

Try again this weekend. I'm am having steering issues and I have ordered a larger reservoir.

Thanks for all the updates. I am surprised there has been problems so far but am hoping they are all worth it! The other formula like yours seems to love the bravo to arneson conversion ( http://www.youtube.com/watch?v=bxjsIl3F3x8 ) Seems like it would have been easier for you since it has already been done on the exact same boat!

Looking forward to updates soon!!!

here is another ASD7M that i did on my boat
http://forums.boatfreaks.org/showthread.php?t=18295
alot of pics and video if this helps answer questions for people interested

I did follow your conversion on Boatfreaks, you gave a lot of very good detail. I did know that for my conversion there would be hiccups along the way.

Once everything gets dialed in, I'm confident the ride will be incredible. I did not expect it to be "plug and play". Anytime you make a major change, some tweaks are to be expected.

Great Thread 47Excalibur, thanks for sharing.

km5125, There are always hiccups with custom high performance machines, but thats half the fun! Looking forward to good news soon. Sucks we have not had the indian summer we are used to getting in september though!

once its dialed in you will love it,,, im still testing props and changing a few other things and love the performance and drivability....plus the rooster tail

Any more testing? pics? videos? Summer is about gone and we all NEED to know more!! Its like our crack addiction!! HaHa

Installed the much larger power steering reservoir and I was able to concentrate on getting up on plane. Like I said before, these handle completely different than my XR's. After trying varied drive and tab heights, I found the sweet spot. Once the drives grab, I raise the tabs, she takes off. I'll post a video if my Go Pro quits freezing!

Looking forward to see it. How are the dock manners with the new reservoir?

Docking is just as easy as with the Bravo's if not easier.

I figured that would be the case. Glad an actual arneson owner answered the question because I am sick of people saying that docking would be harder.

Looking forward to a video!!

+1000000!!!

If you wouldn't mind could you please tell us what the total cost of the upgrade was so others as well as myself can get a realistic cost of doing something like this really is. And also what the resale value of your boat would be with these drives on it. I am glad to hear the docking is great with these drives. Also, how is the slow cruise on this boat for like night boating? Love the rooster tail that those babys throw up in the air!!! :coolcowboy:

With your power, setup and props your tried, what RPM are you getting at WOT:drink:? Still waiting on some video.

Where is that video at with the formula and the Alice in Chains song Rooster. Bad A$$ for sure

And here is the soundtrack one... http://www.youtube.com/watch?v=bxjsIl3F3x8

This one is my favorite. I think he didn't have his trim taps or drives all the way down at the start. Bad to the bone!!! Turn up the volume!

And this is my Cigarette Top Gun now with Bravo 1 drives. My prop shafts are swisted now... Can't wait for Arnesons...

Old Cigarette with old Arnesons.

That has become a true classic.
