What did you do to your boat today?

I don't miss that....at all.

No fun at all but we had to do it unfortunately.... The wood flooring was flexing and their was water stuck in that under compartment that was seeping out of the wood back by the motor. It's a pain, but gotta be done. One thing after another! :-/

It's a biggie too.
That's the last place you want water sitting.

I'm throwing empty cans of coors and butt wiper in the bare hull hoping they finish bit for me 😜

Well here is the both of them painted and bolted up to the Tunnel Ram. I think they look pretty good.

Nate what carbs are those?

Looks good Nate.  Just a little constructive criticism, can your upper plenum be turned around so that the carbs sit more level while on plane?  Just thinking that that might cause some float level issues with the angularity of the engine combined with the angularity of the carb mounting surfaces.

Cheers,

Joe

Hey flushed, I think it may be an optical illusion...look at the line of the hull rim in the back round compared to the trajectory angle of the carbs and ram set up. It might just be me, or the picture but I think nates gonna be alright bitchen setup though! No disrespect intended at all flusher, you could be completely right and im just holding my phone at a bad angle lol

Ok so I was kind of thinking this but was unsure. I bought this setup like this and it was on a jet boat so thought it was ok as is. I will have to look into it.

No disrespect also and I don’t mean to take anything away from Nate’s hard work.  It is just a thought.

Indeed Nate put a lot of work into those carbs and I have great respect for those who wrench on their own, particularly those who pay close attention to the fine details.  I just want the best possible outcome from his efforts.

The installed angle of his jet intake (~4 degrees for standard Berk) influences the installed angle of the engine for drive line angularity.  Inherently, the aft end (the flywheel side) of the engine in a jet boat is lower.  In this picture, it seems that the plenum is installed with the angularity of the carb mounting surfaces angling down towards the stern (thicker side forward).  That combined with angle of the engine install will cause the front float bowls to be much higher relative to the rear float bowls.  This may or may not cause a problem.  He might have enough adjustability in his floats that this never causes a problem.  However, if it does, it will manifest itself as a tuning issue in an otherwise good functioning carb.  Ultimately, the carb angle should be level while on plane.  If you take a look at any form of motor sports that uses Holley (and derivatives) carbs, great effort is made to make the carbs level at ride height.  Manifolds are machined with an angle on the carb mounting surface (see red circle).

Again, not trying to take anything away from Nate and I mean no disrespect by stating my observation.  Just thinking an ounce of prevention is worth a pound of cure.  riverrat, you could be completely right also, it COULD be an optical illusion.  Or maybe I just looked at it out of the wrong eye (I can’t see out of one eye).     In reality, I could not tell for sure unless I measured the angle of the carb surface and compared it to the hull planning surface (next to the intake).  The angle of the carbs to the gunwale, deck, floor, etc. is irrelevant.  Just my humble opinion.

Respectfully submitted,

Joe

you know Joe I'm actually glad that we have this forum and we are all respectful enough to share our own opinions and in actuality I learned something I didn't even take into account... the angle of the dangle of the motor nor did I realize that you could turn the intake around 180 degrees. So I just wanted to say thank you for educating me and its duly noted for when I build my first jet boat. I can totally relate to the angle and how it will affect the floats because Im used to doing rock crawling and so forth.. So all in the end I hope nate gets his setup done correctly and had a blast on his boat... Its fun learning from you guys so once again thank you! :-)

Thanks!
Sorry to here about your bearings, that sucks! I had a blow out on my trailer at the pleasant turn off and my spare was junk too. I had to call a friend to pick me up and the only place open on a Sunday was wall mart at I 17 and happy valley somy wife and kids sat in my truck for 2 hours while I went and got a new tire.

I feel your your pain wife and son also waited with the boat as I went to get a tire a few years ago lol will pick up new bearings today getting ready for Blythe memorial weekend it will be our first time on the lower river can't wait

Intakes only go on one way. But the top half of a tunnel ram can be spun around.

Ya. They were not happy....LOL
I never been on the river at Blythe. Only big river and may try to hit that one in june

Picked up the bearings $50 races and 4 kits man I'm ready will have to meet up a pleasant some time here's the wife's pic for corona's where's your beach
