3.5m HDPE jetboat

Chief engineer (my uncle) suggested that the way I had exhausts go thru the hull was prone to failure so out with cast alloy ones and in with plastic ones

 

twin exhaust dumped under the water line keep it quite and been two stoke should keep the back pressure up

 

left my boat with my uncle to sort out the wiring issue, lucky i did because i put the plugs around the way causing a lot of confusion, it should be on the water in a month or two all going to plain, in saying that i have had misinformed hopes for this old girl before

 

progress new fuel pump in the mail getting close now

 

Thanks to everyone's input over the build, I am happy to announce that that she floats and flys lookin forward to many crazy adventures

Man, I really dig this effort. You have inspired me as I've mulled the HDPE hull idea over for drift boats. Now, because of you, I know I HAVE to do it!

What a great project and congrats on the successful maiden voyage. Too cool and outf___ingstanding!

 

Cheers mate, that's gotta b one of the nices things someone has said about my boat, much appreciated

Where ya at in NZ? I just spent two months on the S Island.
Cheers

Now that you've used this boat for while what would you change if anything? Material, hull thickness, motor and jet size or brand?
Thanks, I like the idea of HDPE and was thinking of a thundercat style boat made from it for spearfishing but was worried about the weight.

 

My uncle is onto his third now, using bigger units and small car engines instead of pwc. https://youtu.be/bMO3xEni8jo
