Very nice job and speedy too!  Interested to hear how she runs out with the jet.  Have been interested to do something kind of similar with my 79 16' Carlson, but have been wondering if a scag may be needed to make it track better with a jet, has that ever been a consideration for you?

That is a consern with me also.. however the hole plan was to make a play boat that handles and runs just like a jet ski. I want to be able to spin it around and “wash out” just like they do. The trick I think is to find the sweet spot in turning control and all around safety.  I’ll find out the first time on the water.  :)  :)   And yes I will be wearing a good life jacket  :o

Yes safety is important.  Maybe with the 115 hp jet drive it wont be too crazy with power and speed so might handle better to enjoy spinning out and things.  My fantasy "roadkill" project has this strange jet drive driven by a 318 Chrysler v-8 so maybe even a detachable scag depending on how I use it might be the way to go because I think it will be very scary at times.

Not to discount your fine job on body work and paint. And the obvious novelty of the project.

I just think you're overestimating power and performance.

For example: CV23 with a good running small block I/O will keep pace with a CV23 big block jet drive.

To perform any breathtaking "acrobatics", I think yer gonna wish ya had a lot more HP.

Always a bit more hp to be had from the V4, but I'm curious to know how well it does as currently configured.  I would guess it should perform in similiar fashion to the Fling it came from, but again, testing is everything.

GT150 is about 150 lbs. lighter then a Fling, which will do 40 to 42 mph.
Put her in the water and see what she'll do ... Take it from there ...

I think you should gut out an old 50 hp Merc or Johnson motor and mount it on the stern, with out the lower unit.
Would be cool to see the look on peoples faces ... LOL

Both the gt-150 and the fling are almost the same in size, so lm thinking it should perform the same as the fling did. But the GT-150 should be lighter and has a shallower draft which I’m hopeing will be the difference in proformance.. again it’s not a race boat, just...  “hopefully” a play boat. and If it can keep up with blue that would be a bonus.     And I could always mount a v-6 omc block on it    ;)

Ya. 40 mph @5K. Mebbe. Sure you could beef that Xflow up a lil. But where are ya gonna find a impeller to match the mods?

Don't get me wrong. I love it. But for starters the crankshaft's pointed in the wrong direction ...

I could spin my CV-23 jet around in a circle just like the jet skis do.  There was a guy showing off one day in a little seadoo jet boat. So I fired up mine and went and spun it around a few times.
I think this has become an addiction.

Wow, I didn’t think the 23 would do it, however the 20 I had did it very well also.

A V6 would be cool … 150 -200 HP would get 50 mph or better.
A V6 block wouldn't bolt up to a pump with a V4 bolt pattern … Would it ?
Is there other impeller to choose from ?

 :)  ;)   I have no idea, it’s just a thought.  Don’t know how different the blocks bolt up to the outdrive. Aren’t the v-6 just 2 cylinders taller?         GO

NO!!!!    Waiting for my seats to get done!!  He’s had them for 2 1/2 mo.  >:(   And I’m ready to fire him!   But keeps saying he’ll have them done soon.   Might have to try it without seats.   Just a couple little things to finish.     Hopefully before the end of the month.
