What you recon its worth - be very good on the mighty Arawhata
Has it enough power ??

I’ve got another small boat with 80hp. It’s spent a lot of time down the Arawhata
110hp is heaps in a wee boat.
Simply don’t have time to finish this one so it needs to go as in a mates workshop.

Heading down 26th - so will talk to the lad down under and see what he reckons
Has got one already - but its a sprint Jet and not practical - goes like a hurd of Turtels but only 2 seat and zero room for gear :-(

PS
What’s the fuel economy and general maintenance required etc etc

To head up and back arawhata you’ll need 40l. End of the day gas is cheap lol
I’d expect 100hrs on Motor before touching it

Boost + the occasional use of ethanol it can do more

Literage/boost/and internals please.

I know of a K24 powered race car that has over 500hp. It's NA but he's boosting it soon with aims to get over 1000hp

It would take a while but in short fully forged internals 9.5 :1 pistons,running 12-14psi boost,Variable with more programmed to come on when vtec comes on about 5000rpm.Flex fuel sensor for ethanol content, Dont really use ethanol much anymore as new motor seems more than enough for this little tub.7" southern two stage jet

So the unit and motor combo are working all good now?
