- - Arneson or #6 Retrofit? (https://www.offshoreonly.com/forums/general-boating-discussion/355395-arneson-6-retrofit.html)

where is the prop shaft in relation to the bottom ?? you say your down on speed with the current setup, at 625 hp ? #6's rob power, take's some hp to spin them, you may spend a bunch of cash and be very close to where you are now..........BTW I may have a buyer for the konrad's if you remove them.....god luck

at that power level I would do an scx helmet and upper switch and run the sc lower. if you have issues with the lower gears you can then upgrade to the scx lower with cleavers... I did it on my tiger along with whipples and went from low 80's to 92 and no prop testing

Couldn't tell you exactly but all parties involved in building this boat (Steve Stepp, Kenny, and Konrad) have all said the x dimension is already pretty high on this boat and stand nothing to gain. Don't know if this references anything but it has been mentioned to me that the boat won't even plane with 4 blades, which I assume has to do with the high X.

In regards to the number 6 I have nothing to personally refute what you've said. I honestly do not know that much about them and am relying on the knowledge of others. Again I have been told that a 700merc NXT combo runs 115, and maybe that's ideal, perfect conditions, who knows. I do believe that boat was staggered (kenny or someone may correct me here on that, not sure). BUT, I would think despite having more rotating mass due to larger components the dry sump design would use less power than the NXT under load?? Plus that's only 150 more hp than I have total. So with all things being even, and especially being my ilmor engines come in weighing much less I tend to believe the numbers that have been thrown around. That would be one expensive rooster tale lol

I have a set of ASD 7m kits on my boat that I installed 2 years ago that I might sell. Freshwater only. Never left in water. Email me for pics,in informati,etc... [email protected]
Thanks Cary

which boat did you buy, I was looking at a few of them that were for sale a few months back. What power?

The Mean Streak. 1000hp a side.

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.

Does Ilmor even rebuild the V-10's anymore? They rebuilt my 700's a few years back but since then I called them with a tech question and was given the number of some ex-Dodge engineer in Detroit for reference in case I ever need to have my 700's rebuilt again. And then there's Boostpower out in Calf who are not just rebuilding them but bumping them up to the 770HP range. Haven't talked with anybody who's ever done that rebuild with them to get their feedback though.

Sounds like you are leaning towards Arnesons, great drives but has anyone done one in in that same hull? My opinion for what it is worth, you are going to spend a ton of money and time on a project that is a science experiment. It will cost more than you think and you will run into the unforeseen. And when you get it all together you get to spend $10k minimum on high rake #6 props. I still dont see spending that kind of coin on that hull. Apologies for the lack of optimism.

The $$ for the conversion is not as bad as you guys are thinking. I have a few other factors at play here that I really don't want to get into. Suffice to say if I'm going to do the conversion now is the time, the financial impact will will be mitigated by some other factors.

I talked to one of the head guys over at ilmor well before I purchased the boat because I had a concern about product support. It was explained to me that most parts to these v10's are shared with other applications. He also stated that they rebuild them at their manufacture plant in Michigan. They plan on supporting the product for as long as they are out there for various stated reasons during our conversation. After easing those concerns I struck i deal on the boat. I'm tired of aftermarket shops (I know there are some good ones) so it was very important to me with the purchase of this boat that I have unmolested running gear that be serviced by the manufacturer of the product.

I believe Kenny told me that two velocity boats made had arnesons, both diesel, which I'm assuming ended up in Europe?!? I did just ask him and he is going to reach out to Steve to see if we can get any statistical data. So yes they have seen the Arneson before, just not alot of them. I don't want to put words in anyone's mouth but I believe Stepp has a ton of lake X experience, hence more experience setting up the 6's.

There's a pair of #6 boxes and transom assemblies in the swap shop if your looking
