Hi; folks anyone got an opinion on which prop to try on a 27foot riamar deep v ,The drive is fixed/non trimmable,running gear is a yanmar 6ly2a stp/440hp running through a zf 220/ratio 1.237/1 boat weighs exactly 2120kgs loaded,is a heavily raked prop better suited here given that the drive does not trim.

In deep V applications, yes, more rake can help. Your in a tough scenario in that there aren't many test props for your application. A base line set of numbers would help.

Your current performance numbers with a desciption of the current propeller. These numbers can include all or some of the following.
Ability to plane.
time to plane.
Trimming capability.
venting in turns or rough seas.
tracking and boat attitude.
rpm vs. speed increments in 500 rpm increments.
WOT rpm versus speed. (key)
Any other seat of the pants observations.
