I think I remember someone stating that there is about a 10% extra speed when switching to the arneson drive's with the larger surface prop's .
also if I remember correctly '' to much partying in my youth " :)
the hustler 38 with 525's ran around 10 mph faster with the surface drive vs the bravo xr style .

Can you throttle arenesons like you can 6s? how's their response?

Yes, they react the same.

DrGaryDC. I prefer to run the props out which is backwards for Arnesons. The boat handles well until a little over a hundred then you gotta pay attention. I don't thinks its an Arneson issue, I think the 1986 Cigarette is about maxed out.

cougarman. These are old drives off of one of Gentry's race cats.

Panther. I never dynoed them but my guess would be a little over 800hp a side.

Why do you spin them out??

Im curious what my 86 apache would do with arnesons or even dry sump 6's. Still has the old SSM 3's and runs just under 100, approx 800hp

I wonder if #5's would be the easiest upgrade if you're trying to raise the X dimension to gain speed. That would raise your bullet a lot higher than it is now and you could space down if needed. Probably the easiest upgrade I would think?

I was checking out the apache in the Solomon's island pits and it looked like the drives were pretty high. I imagine 5's would end up too high since they are 6" shorter than the 3a's that are on it.

Nose high= Rocker that's needed with surface drives, just like Sutphens which have had surface drives and has plenty of rocker.

A 41 should fare well with Arnesons and I have many times wondered why they weren't tried already. Maybe Bobby S would be the source to ask or just measure your rocker. Richie Stuphen surely would give advice also.

We talked many hours once about this particular issue a few years ago on general terms and he cemented my belief that a boat with enough rocker and even a delta pad do not need steps...

Bobby S for sure and even Mark Wilson from Twin Disc. He works with them everyday on all kind of hulls.
