Surfriding Ok I'm a newb. Acceleration breaking up after riding surf

[swapmeet]

Searching from my phone, so the search feature isn't helping me.

Just arrived at the gulf. Sprayed down engine bay with silicone spray and hit the surf. This is the second time my skis been in the surf, first time it seemed problem free.

So today I ride for 30-45 min and if you pin it or even hold throttle at 1/2 or 3/4 it runs choppy. On and off, on and off.

Last time I rode surf I greased my electrical connections.

Any suggestions from the old salty dogs?

Try gapping the plugs down and see if it gets better.

Wait until its dark out, sprinkle your engine bay with salt water or don't rinse it out, hit the green button and watch the fireworks. If the short is in the coil wires somewhere you'll see it arc. I've draped towels over my head and engine bay to look for this in day light as well.

probably a leak in a spark plug wire. start it up at night and you'll see where its grounding out. i had a zip tie and short piece of fuel line keeping the plug wires apart/together and one time it was leaking from there. i moved the zip tie and it ran perfect.

Ok, I already rinsed it out, so I hope that isn't bad.

I have the zip ties with fuel
line in between spacing out the plug wires, and I have water line protecting it where it drapes over the head pipe. Also my plug wires have that mesh protecting the plug wires.

Try it anyways once it's dark and see if it lights up or take some salt water back with you if you're still on the beach. If you're done for the day then it is what it is...you can go through and check the obvious stuff like grounds, start stop connections, etc and cake them up with dialectric grease but it sounds like plug wires/coil. If it runs fine after gapping the plugs down it's there.

I tried starting it after I rinsed it off and re-routed the plug wires and it did the same thing. The Mosquitos here are unbelievable. It hasn't been worth the additional blood loss to mess with it tonight. I'll try bumping the plug gap down tomorrow and see how she does. Thanks for the advice.

Definately sounds like your coil wires/boots are having a problem with the saltwater.

Agreeds doesnt hurt to cut the wires back and see if that is the problem its fixed my issues with salt numerous times

Classic issue with guys hitting surf rides coming from inland fresh water. 90% of the time, coil coil coil, salt water promotes arcing, resulting in the ski breaking up. Its intermittent based on the water splashing up when you bounce around on waves. New coil will do the trick.

Tell me about it. Where are on the coast are you? I had the exact same issues as you when I took skis that worked fine on the lake to the surf this summer. Coil wires were arcing like crazy.

Our surf coil will fix you right up. JM sponsored rider Brandon Lawlor won the pro surf slam this year with our coil.

Had this issue when i built my Rickter. Ride in a straight line and was ok, throw the ski around and would miss fire. I had a spare coil so tried that and problem went away. It was a Yam coil that was the issue, i swapped it for a Kwak and it's been problem free since.

Saltwater in the start stop.

/\ agreed.
turn idle down and unplug black & white wires on S/S plug & try it again

Another possibility and easy to test.

Sorry for not updating this. I went to the local parts store, picked up new plugs, gapped them at 25 thou and it's really helped a lot. I ran two tanks through it yesterday and it only broke up a few times and it was minor.

Same issue happened to my wife's ski, plug change with a tight gap and it was all good.

Also switched over to WD40 instead of silicone.

I have to close the gaps on the plugs of mine to where they are almost touching.
Salt water does silly things to skis.
