Default Pair Acme Propellers 19X26

Nearly new pair of high-tech CNC machined Acme Nibral props in 19" diameter and 26" pitch bored for 1.5" shafts. Just scanned, polished and brought up to ISO Class 1 specs by top quality prop shop. Only one season of use. Never grounded, damaged or repaired -- can't tell from new. Would cost $2700/pair new but can be yours for just $1800.

Are these for the Bertram? Normally there is some tolerance on smaller diameter depending upon what gear ratio and engines you have. These props have four blades and quite high "DAR" (blade surface area) so you might be able to use 19s. You would find that having more tip clearance might reduce slip and make for less prop rumble too.

They were on a Carolina Classic 28 with Volvo 330 Diesels. I swapped them out because the engines were hitting the rpm limiter at WOT at only 90% power. My prop shop said it would be better to go with another design prop that had more blade area rather than trying to increase the pitch on these to reduce the WOT rpms.

The Acmes are indeed extremely well finished props and have excellent performance in terms of low slip and "bite".
