Mercury Racing released a new Propeller Slip Calculator App for both Apple and Android devices. The company's prop guru talks about it in the latest Mercury blog.

I tried downloading it...didn't work.

Big deal, Hering app has been on my phone for 2 years. I would say they are late to the party.

Cool, I used to have the herring app, but it's not in the App Store anymore. Just tried to download the merc one but it's not working yet.

Does not work for me either

I also have the one from Orange Dreams "Boat Propeller Calculator". Works better than the Hering as there are some glitchs with it. Android BTW

Actually for the Merc app to work properly you have to pay 3 times as much for it.

Just downloaded it, works on my iphone fine

Yes working now on mine

Apps, blogs, Apples, Androids. Balderdash. In my day we calculated prop slip with Part # 90-86147A1 (slide rule). Get the tech gurus down to the "secret room" and get them working on shaving the weight of a 400R or bulletproofing the Bravo instead of sitting around peeing on the wheels of progress.

But seriously, the app works now and I like it, a lot.

Ive been using the app "Topend Free" and its been great for a while
