There were a lot of them for sale on BBC shortly after they fist came out. I don't know why they were all getting rid of them that quick.

If you check over on BBC, and also on the Merc blogs, some combinations are having a lot of problems with the ProMax prop breaking loose right at break during hole shot. Some have tried a cav ring on the front, welding a flair ring on the back, and drilling PVS holes in combination. Seems like some have great results and others can't get the hole shot right. Most say once on plane acceleration is great as is top speed.

My experience on my setup allows me to plane off at 3500 or so. If i floor it it will blow out but flooring it is not necessary. This is compared to a same pitch pro et that i have to rev to 6000 rpm for 30 seconds to get my boat on plane. No matter what i do my boat hates planing with the et

I can say I like both pro et and promax if your mid and lower are stock you will blow out any prop. if it has a snot on mid or drilled you don't need holes in the prop that's way the bbc guys had that issue. my lower was drilled for hole shots no holes in any of my props hope this helps greg
