BOATING WITH DEWI -EP19

We are testing Tohatsu 50Hp 2T, with original propeller 12 inch pitch and aftermarket 14inch pitch.
surprisingly the original propeller (12 inches pitch) is clocked 30.8 knots, and 0.8 knots faster than the aftermarket 14 inches pitch.
this condition could be :
1. due to sea current.
2. due to original propeller is already designed, tested end engineered for the particular engine.
Many factors can contribute to this result, as we are not the certified test center, we would like to say this video is unable to proof anything, just a picture what we were doing on that day.
and we can calculate the boat speed by knowing the propeller pitch, and the engine rpm, and also the final gear ratio.
We are non-commercial channel, we are more than happy to receive your appreciation for our videos by your like and subscribe.
Thanks for watching our videos, and Thank you very much for the like and subscribes.
6:31 the sub-title should be test 4 with propeller no 12!!! typo....

siap kak, iya nih kita dulu pernah punya 25Pk, belum sempet dibikin video ud keburu dibeli temen, nanti deh mudah2an Yamahanya melihat channel kita, dan berminat meminjamkan mesin untuk di sea-trial, di kelas 25/30Pk memang hanya Yamaha saja sendiri sih...

Pak kalau mesin tohatsut 18hp bisa diganti propllernya ke yg lebih besar?

[@elmovacmarine]

pada prinsipnya bisa saja kak, tapi semua disesuaikan dengan berat boatnya ya kak? kalau boat fiber kan 17 kaki seperti kami punya itu ringan
