Hi,
Bought and rpm optical tachometer and went for a sea trial today. Below are the results:
There are 3 columns in the table:
"rpm gauge", "measured engine rpm", "shaft rpm"
1000, 710, 330
1600, 1058, 497
2000, 1457, 680
3000, 2115, not measured
3550, 2522, not measured
The max rpm measured is 2522 yet it should max out at 3000 (WOT). Thats what the manufacturer states. This means that I am over propped.
How does this effect my engine? the speed of the boat?
How will a correct propeller affect the speed of the boat?
Thanks
Yoram
