I appreciate the focus on data and am interested to add to it later this summer.?
Out of curiosity - Having no formal seafaring training, is there a canonical text/protocol/reference on how to perform sea trials for new equipment? I¡¯m thinking things like checklist of environmental conditions to note, guidance on distance, any procedures on which tolerances to push etc? I can deduce the bounds I want to test or gain confidence in, but I¡¯m curious where one goes to learn a little deeper.?

13" with 15.5 pitch? ?Or 15.5" with 13 pitch?

?Eric,
I agree with Patrick ... incredibly useful.
I've asked a follow-up question elsewhere, but will ask it here too, where it seems more to the point of the post topic.
What is the reduction ratio of your transmission?? [At least, in your photos, it appears that you have some sort of transmission or reduction between the motor and prop shaft.]
I've also already noted elsewhere that you're running a 4-blade wheel of 13" x 15.5" dimensions.? [Also a very helpful detail for verifying 3rd party prop estimating tables.]
Thanks in advance for the additional detail ... I would just like to work out the prop shaft speed to go with prop information.
