How can a poll be irrelevant? For instance, perhaps we'll find that nobody uses positions 3 through 5. That would be interesting wouldn't it? Perhaps we'll find that 50% of people use position 1 an 50% use position 2. That would be interesting, too, wouldn't it? Or if 80% of people use position 1?

Yes, I know it depends on many conditions, but I'm sure that folks don't bother to change trim holes because of the hassle. I suspect that the vast majority of folks find the one most versatile position and use it most of the time.

I'm trying to find out if there is one or 2 positions that work well for most people, or if it is all over the map.

I use position #1. I get too much cavitation (or ventilation, whatever you want to call it) in #2 and #3 is just ridiculous.

A tech at the Inflatable Boat Centre (a huge dealer for inflatables on the West coast of the US) told me that most users use position 1 or 0. I imagine that position 0 means that the trim pin is removed.

Chopper


Cleaver


Bunny



Dont you have Google in Canada

Seriously, they are all types of prop. The negative trim spacer allows you to change the angle of the engine saddle.

Basically a black of wood used to space the top of the engine out, so trim 1 is effectively like having a trim -1 or -2.
choppers and cleavers are both surface-piercing propellers used in high speed applications, so the setup on them won't really relate to standard propellers. A bunny prop is just a standard looking prop, because of the shape of blade, known as "bunny ear".

I'm wondering if this is like a spun bushing since Hugh Hefner is very much alive.

So there have been 6 responses :

position 0 (presumably this means pin removed): nobody
position 1: 1 person
position 2: 4 folks
position 3: 1 person
position 4: nobody
position 5: nobody

Position 2 seems to be the preferred choice for 2 out of 3 Sibbers.

Anybody else want to chime in?
