TW28 propeller
Posted: Thu Jun 23, 2022 3:47 am
Finally, I'm going to buy a propeller now for the TW28. But... there's no exact answer and I'm a little bit confused.
I have a Beta Marine 43hp (Kubota) 2800rpm engine with TMC60 (2.54) and a Python Drive in front of the 35mm axle. Now, Jacques proposed a long time ago a 17"x13" propeller for a similar engine and transmission, but the dealer suggests to me 19"x17". I wanted a 19" 3-blade propeller as there's enough room.
I checked different online pitch calculators and I'm even more puzzled. The data ranged from 19"x11" to 19"x14" and one calculated the same 19"x17" dimensions as the dealer offered. So, maybe this last dimension could work.
But I would like also to ask for real experiences from builders and practical people as obviously there's no hard science working here. Especially because the hull of TW28 with box keel is not common.
Wish you nice summer on your boats or successful boat building.
