With the driveline fitted in the hull using lashings of epoxy glue (Hint: Hwen using the Poundland stuff, buy fresh tubes) the motor was going to have to sit at a funny angle due to the whopper prop fitted on the end of it.
I contemplated making a plastic support but decided to try something new. With several lumps of grey styrofoam kicking around, why not use this?
Chopping this to size worked well. I kept shaving bit away until the motor would fit with everything in-line. Half an hour's work and I had something that worked.
Thoe motor is fitted with UHU POR adhesive - a foam-safe clear glue. I wasn't sure about this, but it seems to have fixed the foam to the hull and motor strongly enough that when power is applied, nothing falls apart or even looks like it might. I wonder if the foam even provides some cushioning effects to keep things quiet?
Anyway, with things dry, I lashed up 6V worth of batteries and tried it in the pool.
