hi there does anyone know What's the biggest jet drive I can buy for model boating purpose
I've seen a graupner one around 300mm long and 70mm
wide is there anything bigger on the market.

Thanks all

These are pretty big!

I think this is about as big as you're going to get, for Zenoah G260 petrol engines

when you look at the shape of a full sized impel or and the ones they fit on models you can see why the models are not that efficient

But they're not for model applications. How many models do you know you can fit a one litre V6 in? Not many?

So strimmer motors are ??

Proteus,

Single cylinder 23cc engines, not 6 cylinder 1000cc engines.

The best model V8's are the MHZ USA ones. But they won't turn that impellor.
