RE: SV-26 prop size ?
I'm just going by what Mike Dooley of RCS told me. I was ordering props at the same time that I ordered the engine. I was going to get a 16x8 and an 18x6. He told me the the engine likes the 18x8 after break in and not to waste my time with the 18x6. Since he was the importer/servicer of the engines, I figured that he would know what his engines liked for props.
