Thanks for the reply John

I think I will go for a 35amp controller using the Marlin direct drive.

I did buy the shaft and the prop was recommended by Brian at Essex Model Centre. However I think you are right and the only way is to test with different size props.

I think also that I will go for the Titan sealed Lead acid battery. It is rated at 7AH. I am not sure about the weight though and I am mindful that this will be an issue. Hopefully this would give a good run time. I will certainly make sure that there is at least a 25amp fuse inline.

This is the first boat I have built in about 9 years as my other vice is model railways (Narrow Gauge), so it’s like starting from scratch again.

Your posts as always are gratefully received.

Best regards

Alan,
Glad to be of help, but please bear in mind that every boat is built differently, and my suggestions have erred on the safe side. People can only give you guidance thru their own experiences and techniques.
The way to do it, as you are restarting again, is take it easy and make no large financial outlays until you start seeing the results of your experimentation. Only buy the basics you need to get yourself up and running. In fact if it was me, I would get the hull and superstructure to a waterproofed state, do your experimentation, then when it is all sorted, go back and finish off the build by buying all your fittings, you will then know, apart from maybe a bit of ballast shifting, you will have a good scale model.

Best of luck with your project.
