506 Dinghy Davit - Swim Platform Rating?

[crabshack54115]

I recently purchased a 2000 506 and need to add a davit of some sorts for our Gala v360 dinghy with 40hp (550lbs). I’m considering a Hurley H3O+ on an extension off the stock swim platform. Does anyone know what max weight the platform will support, or has anybody had success hanging a large tender like this off the back of a 506 platform? I’m trying to determine if I should add any support before installing.
