Daytona. Crash box running in reverse
Have a question regarding Daytona crash gearbox at present have crash gear box (FNR) in between TT 502 and parallel drive connected to ASD6 drive is setup to run RH 19 spline props was wondering whether anyone has had has had experience with putting Daytona box in reverse to run LH prop? i have selection of LH props with different pitches to the RH prop and thought about tested them understand that some guys do this with bravo drive just wondering whether the Daytona crash box would handle this? |
It won't handle it. In forward it is straight through. In reverse there is a gear involved that is not designed for full power.

Okay great thanks for letting us know |

By default you have a LH rotation drive with an in line model. (your running a normal rotation GM based engine?) The crash box, and most all of the crash's made, are not full time forward/reverse capable. |
Yes conventional GM engine, bellhousing, gearbox, parallel drive, direct surface drive final prop RH This is okder photo need to update as have the mounts all finished now https://cimg2.ibsrv.net/gimg/www.off...b62243cc9.jpeg Older photo |
found a more recent picture of the setup
need to upgrade my pictureshttps://cimg2.ibsrv.net/gimg/www.off...976f94e898.jpg |
Ok, I see the Casale changes your rotation. |
Glad that someone else is dealing with a crashbox. Mine is inline to the arneson (BBC spinning LH rotation). I just ran it yesterday in reverse with a right hand prop. It ran fine. Only problem was it was kicking a little oil out the vent because the output gear is right below it (simple spur gears). I'm about to go to a z box like you have. I like your setup!

is scarab with the arneson 24' ? what prop you running now? I'm a little way of putting the boat in the drink, however interest to learn what others have cheers Brett |
I was going to do one on my scarab. This is a 29 Sanger alley cat that needs some work. The motor I have in it is around 450hp to a sp1000 drive. I made a bravo 2 prop hub fit it so I can run Merc props. And i just tried a 24x14.5 pitch small hub prop. I'm going to try a 20 or a 19 next. The low power and direct drive really kills it.
