Hi there,

I’m new to boats (mostly fly slope gliders) but I’ve mean playing with this little concept …. Just something to mess around with.

Specs:
Length 14”
Beam 4”
Deadrise at transom: 11 degrees
Motor: TowPro Brushless Outrunner 2408-21 Delta

ESC: A 12A
Battery: 8-Cell 1100mAh NiMH

Here are a couple questions:

1. Will a boat like this need lifting strakes or chines? See Pic. What’s the best way to make/add them?

2.What’s the best way to shim a threaded 3.2mm motor shaft to fit a 1/8” solid coupler

OR
Should I use a Dumas dog bone universal … I’ll still need to shim the shaft

3. I plan to run a solid shaft surface drive; can I use any of these (I’ve got these)

4. How far aft of the transom should I place the prop; I’m thinking @ 2.5”

5. How much freeboard do you need to be safe? My float test, with gear, showed that I only had a 1/4” clearance at the stern. Maybe I need some smaller batteries.

Any comments or suggestions welcome
