Ah, that's different cos you said they wouldn't last 30 seconds, without giving any qualification.
I dare say they wont if used as fully surface piercing but I used to run mine with the top blade out of the water and it didn't give any trouble. The boat didn't go any faster though.
It didn't go slower either but the exhaust noise was, err... sporty so I gave up lifting it out. One of the neat tricks when using it for cruising, is to get up to speed, lift it out of the water and because the load reduces it pitches up but when it was gently lowered back in it stayed pitched up, then the engine revs dropped a couple of hundred and the boat gained a couple of mph.
