I haven't found a GPS will give the REAL speed in open waters like rivers or lakes. A GPS instantaneously calculates distance of movement divided by time to get the displayed speed. It cannot allow for wind, current, tracking swings over the same course, and declining battery power with discharge. For example, if you are fighting a headwind it might show 0 mph when you are really going 3mph just to hold position, which would be a HUGE error!
APC props are under $5 but will need to be adapted from their 1/4" hole to the larger troll shaft diameter. I find the longest EQUIVALENT props to be more efficient, for example a 12X4 might be better than a 10X6 mentioned in the reference.
Hope this helps.

[quote MasterDaad]I don't know yet. The tests I saw were on, I believe, an old Endura 36 using a 10x6APC.
On the C30 I'm planning to take a smattering of 8-10" props to try. I'm a model airplane guy so I already have several sitting around.
I may take just the motor out to the local pond to try it and see how large I can go without over-amping the motor.
Before I can get real data including GPS speed I'll actually have to find and buy a toon
