What viscosity is best in a Bravo 1? I have used Sierra Synthetic forever, and thought I might try Royal Purple since I use their Racing 51 Oil. I have looked on the Seirra jugs and there's no weight rating and there web-site was no help. R.P. has three weight ratings on there gear oil, just trying to decide which would be best, so I'm calling on the power of OSO!!
Thanks, Mitch

I'm pretty sure Joe and Wayne and the Sunsation factory use the AMSOIL Marine Gear Lube. That is what I use in my 32 MCOB SS
