E-TEC 25 or 30 for a duck boat?

[duckchaser]

I am looking at re-powering my polarkraft MV1675DB duck boat. I am replacing my 2003 Mercury 25hp motor. I am looking for a long shaft, tiller, electric start with power trim and tilt. I would like to run a stainless impeller in the shallow stump filled waters I run in.

Will running a stainless prop give me cluth dog rattle like I have heard on Suzuki's?

I am not encouraged about durability after reading of the many problems people have with these motors. Are there any owners out there that can give me a long term review? I would like to think I wasn't taking a big risk in buying this motor. Any comparison to the Merc 30 EFI?

Thanks!
