Hi folks,

I have a 31 Afr Cabin from 1977.
I found both props stamped with ALCO 18445. One LH and one RH.
Which size is this? 18" x ??
Is this the correct size Prop for these Engines? in the Archives i only find 16" props given for the MD32 twin install.

Boat seems to be a bit slow , reaches approx. 3900 to 4000 1/min max....


any advice would be appreciated!

I’m running 18x20” on my twin TMD-41 (150hp). They’re a perfect match, så less hp in the md32 should suggest less diameter or advance
