Hi Grant,
Right, it slipped my mind you already had ordered HRB Lipo's...
The rubber seal at the end of the wet well depends on the size of the wet well tube; it should be some kind of a rubber grommet used for steering rods, just a larger size, fitting over the end of the wet well with the brass tube in the middle, supple enough to allow some up and down movement of the stuffing tube, while the Teflon liner does the actual bending when the powertrim is moved up or down.
We're talking 1-2°, as installing the powertrim at the correct height in the transom to begin with is the best way to avoid the need for excessive bending of the propshaft.
I'll have to look into that, as I've never used a wet well / flooded stuffing tube.
Different sizes silicone tubing spring to mind...

Props for this size boat and motor are from 42 mm upwards to 48 mm, both two and three blade.
I would not buy metal props, but start with the Graupner 2317 series, these are carbon filled props with a drivedog fitting for the 4.75 endpiece you need.
Get at least one 2317.42, one 2317.45 one 2317.48 to start with, so you can get a feel for which size prop works best.
Once you've dialed in the boat and you're comfortable with running the boat full throttle in light chop at 50 mph, you can think about getting a metal equivalent of the prop(s) you prefer to run in different conditions.
If the ampdraw stays within reason, you can even try a 2317.51, but you'll have to watch the temps on Lipo's, ESC and motor.
The Graupner props don't require sharpening and balancing, which is a must for metal props.
Most metal props need to have the blades thinned, sharpened and balanced to work properly.
Exceptions are the aluminium CNC props, but these are not my favourites, as the soft material dents easily and fixing that is hard to impossible without ruining the prop (even more).
