Update: drilled holes for versiplugs. Foam is soaked and been draining for two days. Definitely the annoying type of foam and I’ll have to cut the tray open over the winter and remove that crap. More annoying rickter poor quality nonsense.

Good info thanks! Honestly I feel like trying to seal it is a losing battle. Maybe I’ll add a scupper in the pump tunnel like my XFS. Prob not smart for surf I guess

When it sits in the shop on a cart with an angle towards the front, the engine compartment will fill with some water in a day or two from one of the seals at a water line so I know there’s water there. I’ll add a drain. Hopefully they used closed cell foam.

Just built an XFR as a surf/rec ski. I believe the trays are foamed and I’m confident mine is getting water in the tray. Trying to seal it will be a losing battle. Anyone know what type of foam they use and wether or not it will drain if I add a drain? TIA -Jordan

Idk if this is any help… is the edge engine compartment similar to an Xfs or XfR? In the Xfs and XfR, the powerfactor pope sits very high with the PF box. It almost hits the top deck. If the edge is similar it will be tight. I think TNT pipes are pretty big IIRC

Hey that’s the jet ski industry. Top dollar for mediocrity

They are good carbs. Just crap epoxy

For what it’s worth, SEs have the same plug and epoxy in the same spot. whatever they use fails in 2 rides and clogs the undrilled returns. Everyone just grinds it off and repairs with Jb weld tank weld. I also drilled my returns and run a filter before return jet because I was tired of dealing...

It’s running great again but I didn’t find an issue. Cleaned carbs, pressure checked motor, pressure checked cooling system, fixed one semi crusty wiring connection. It was either they connection or some junk in the carbs I just didn’t see.

Was kinda hoping that was it but crank is not out of phase. Checked with dial indicator.

Ok ok I’ll check it with an indicator in a bit

It’s not suck but good idea. I’ll at least rev it and check

Reeds are all fine. That was my first thought and would make sense

swapped plugs yes. Have not swapped coils. visually spark looks identical on crank test but that doesn't mean much. ugh i hate diagnosing ignition problems. Maybe this is the excuse i need to switch my 1200 ski to my new ignition :)

Visually it looks dead on. I’m pretty confident it didn’t move - at least not enough to cause this. Good thought though

Idk who all makes butterflies but I know mark Erickson has made them before.

Hey all, I'm still going through everything trying to find the cause here but curious if anyone has ever seen this. Ski has been running kinda crappy. feels like it loads up. If i keep it cleared out it makes decent power. Pulled head and all transfer ports on front cylinder are almost...

Looking for a reasonably priced set of flower booster Novis or full spec 48/49s. Reasonable price is important. This is for my 3rd big-ish motor ski so have to make sure wife doesn't divorce me. Ok with carbs that need some work. -Jordan

Got the new revision running. No hardware changes needed! I was so focused on the crank signal circuit that I forgot I had to populate a capacitor on the 5v rail which is through hole so china factory doesn’t install it. Noisy 5v signal was the problem. Without the boot loader it starts super...

I know this is super obvious but make sure it’s not in setup mode.
