A Bravo drive cannot "slip"

Could be the coupler rubber slipping

Put 1oz of Zmax in & it will slip

I have to go with Griff on this one. Wheres the slip come in at? Shaft from coupler to all gears all the way thru to the prop. No the rubber coupler won't slip either unless it's broken. My guess would be cavitation or the floor fell out on one of the upper gears. I blew an upper awhile back and reverse still worked fine but no forward on that side.
