I agree unless you REALLY love the boat.... go buy a Fountain with 600's staggered will go 100+ daily and be reliable.

I just finished a project that I used the Arneson ASD-8 to handle the massive torque, " https://www.offshoreonly.com/forums/...project-4.html " This drive is as simple as it gets with minimal parts to get the job done and Rik is always just a phone call away with a huge wealth of information and first hand knowledge. As long as the boat is a stepped hull design with sufficient lift, I would go Arneson! Hands Down......
The #6 dry sump would be a second choice only if I had to have huge amounts of lift on the bow. My project was a cat so Arneson was a no brainer. |
Being blunt, I'm okay with the $$. Before deciding on this boat I wanted to be in the sub 150k range and it was hard finding a non bravo boat with low hours that had factory power with un cracked engine cases and reliable drives. This boat only had about 150 hours. There were a few slingshots that tempted me because of the arnesons they had but the aftermarket power concerned me. Plus this boat was a good deal, and should I have an issue ilmor is located right in my home town and the guys over there are very stand up. Another fresh factor is I have another boat and have been going through some pains with the brand new 540's and it has left a real bad taste in my mouth. I've never been one to not go big power and custome stuff. I just wanted a boat I could put the key in and use, and decided that was more important than going deep into the triple digits. I do not care for the beaks and so my only other real option was a low hour OL or whatever with 700/NXT, but then your talking well over 200k and I didn't want a loan. I do have another call with konrad today and have not totally ruled out keeping them, I'm just leaning very heavily towards not. |
I did the arneson conversions , it was a pretty straight forward install ,worked out well and I liked the results . The only thing I did not like was paying for the sets of props used for testing .

The guys who built the boat recommend sixes and you question that? There’s a reason the fastest v bottoms have six drives on them. |
I've never owned a #6 boat but I do love my Arnesons. Simple, reliable, efficient.............and fun.

I like the idea of arnesons in general but the fastest V bottoms all still have some type of normal outdrive. I think this is due to the better leverage they can create for bowlift. The proof is in the pudding. Sounds like you’d be money ahead to find a 700/6 fountain. I’d think they are in the budget you’re discussing and reliably run 115+. I am a big fan of velocities though. I’d really expect your setup to run better. Either those drives suck tons of power, and not hydrodynamic, your props are wrong, or the 625hp isn’t there. Illmors generally run better than a BBC due to weight and rpm. Velocities don’t run faster with stagger though. I think having more weight in back helps them run on the pad better. I’m still liking the idea of trying boxes, I’ve not heard of a Konrad with them, but it’s certianly cheaper than everything else you’re discussing. i don’t think arnesons will work as well on a velocity because that boat really needs to get the bow up and packing air on the pad. |
I will call Craig Colabella and ask about boxes, good idea and thank you. I did ask about blue printing and he basically said with the cost of that, and maybe maybe 1-2 mph he didn't think it to be worth it unless I was racing. Which obviously I am not. The Konrads really do scrub that speed, literally everyone I have talked to has said so. My understanding in talking with Konrad themselves is that their drive was initially set up for diesel applications with the Military. Being built to be used in the harshest conditions and not break. I don't think eeking out every last mph out of them was a major concern when it was initially designed. I really do love Velocities as well, I'm not trying to start a war here so I'll just say that a fountain is probably not in my future and leave it at that. They are great, fast boats, just not my cup of tea.
Also, I do want to clarify. Steve and Kenny did not advise against the Arneson, they simply said they had a concern with bow lift and had not worked with the product before, meaning it may take a little longer to set up. Rik from Arneson alleviated the bow lift concern. They did also go on to say if I did do the conversion that either would be a stout, efficient package that would help wake the boat up. |
Just wondering if Steve suggested going to side by side instead of staggered as a side by side 390 Velocity is faster then the staggered. I do realize that will require even more dollars, LOL
What ever, I am enjoying your project and with Kenny and Steve helping you will end up with a fast good running boat. Padraig |

Not to sound stupid here but I just don't have a lot of experience with modifying bravo stuff. I know the term stand off box and adding one really has been mentioned alot around those drives here on the forums but I've never looked into that. I thought my boat already had them and it does. Mike over at Konrad (incredibly helpful guy) pretty much re iterated that I am at where I'm at with the Ace drives. I have a high x dimension with the shorties, drives are pushed back, and I'm propped right. Blue printing in his opinion as well would be a waste of money on their drives. If I do keep the Konrads I will be refinishing them, that is for sure. Going to have the paint removed from the lowers and left raw as well. https://cimg5.ibsrv.net/gimg/www.off...77df260380.jpg |
