Thread: Mini jetboats with Jetski engines

Looks like I have sorted a hull... around 3.6m, might end up being 3.4 yet
Its a hull a guys down sth designed in cad and built, and is now scaling up. 1.5 at the chine.
Hes going to build his soon and if all ok I'll buy the plans and get a mates old man to lazer it out and will find someone local to weld it up.
Basically pic below scaled up 20%

Umming and arrring engine wise.
Was going to use a 1100 Kawasaki but speaking to a mate down sth thats done a couple of wireups in the, he seems to think the Suzuki M15A is the way to go.
Would be quieter, more fuel efficient, but heavier 100kg vs 70kg which I dont think makes that much difference, and would need to be marinised
