Hi,I own a V-24.Love the shape of the thing,wanted something different for a change!!
The fuji engine is underpowered,at best i had 30mph out of it from standard using the original pipe etc.I had the engine porting and timing modified too along with a performace pipe,made a vast improvement.But I race mine here in the UK and it did not keep up with the others!!!The only thing that broke was the manifold.If you read past forums on this boat you will see this is a common problem.
I have now changed the engine to a o neil brothers Sikk 27cc motor using a irwin tuned pipe.handles the rough fairly well.Plus I had mine strengthened and added some more bouyency just in case! : )
Regards OMRA
