Hi - I've seen informaiton on the E35 where some owner said he had a 14" prop. Most A4 Props are 12X7. I'm wondering what is the largest Dia prop one can put on this hull and use the current shaft? I'm installing a M4-30 and with the 2:1 drive a 12" prop cannot be pitched even with a 3 blade to take avantage of the HP. Also, has anyone used a self feathering prop on a E35?
