Hi Dave and Doug. I love it when you two start chatting it's like tipping a cornucopia of knowledge all over the floor of my workshop.
I found my original notes and the motor is a Mabuchi TD224 23.
The shafts are: S.H.G Marine Miniature Propeller Shaft Assembly
Stainless Steel Propeller Shaft assembly with Brass Outer Tube
M2 Diameter Shafts
An excellent range of miniature shaft and tube assemblies with Grade 303 Stainless Shafts and Hard Grade Brass outer Tubes.
The outer tube diameter is 4mm, Shaft Diameter 2mm The Bearings are Oil / Water lubricated Acetyl material and are extremely hard wearing and quiet, The Shafts are Threaded at one end with an M2 Thread. The propellers are:
RADIOACTIVE MA 3045 RC MODEL BOAT 3 BLADE 30MM PROPELLER M2 THREAD 2 OFF.
As my Nimh battery is reading 8.09v so it's unlikely that there is a weak cell, I will recheck all the readings and be a little more precise to ensure I am not leading you on a wild goose chase. The biggest clue is that I have just measured the battery holder plate. The measurements are L130mm, H36mm and W65mm. Looks like the only battery that will fit is the PS-630 6V 3.0Ah 150mA 134(L) x 34(W) x 60(H)mm 0.7kg or similar. This looks right as it will probably take care of the ballast issue and it's no wonder my normal 6v battery wouldn't fit. it will be a couple of weeks before I can put her on the lake but at least the battery is ordered. Thanks again for all the info. One final thing... Can you tell me how to measure propeller pitch?
