1984 sn2001 cuts out at higher RPM? Help!

I'm planning on putting in the water again tonight.....

what things should I be testing while in the water? [its a good 2hours by the time drive to lake/unload/test/load, so i would like to try as much as possible?]

I plan to ::
1. test fuel vent [remove gas cap if needed to verify]
2. test coil voltage to distributor to be sure the isn't any voltage drop.

I don't have a fuel pressure gauge, but might be a good idea to pick up some flexible fuel line and barb connectors and put a gauge before carb...?

any other diagnostic tests I can perform while its in the water that you guys can think of?

did you take the cap off and look at the contacts?

SN20011984 - There are some real pros on here that can help. Take a picture of your engine and post it. I was having the same type symptoms in my 1991 and thought is was fuel. Turned out to be something else once guys on here saw what type of ignition system I had. The knowledge on here is amazing. Welcome to the club.

Get the kids out on the water

You bought a boat designed for skiing and you are pulling tubes???
Welcome to CCfan, Dump the tubes.

so yesterday I did take the black hose off of that connector and made sure I could blow through the black hose. Is the checkvalve in the 90degree part attached to the tank? I was able to push a small wire through it? it felt like it was a little stuck at first? not sure I'm in the right area?

thanks for the help.

Guys,
Hello....new to the forum as I just picked up my first Ski Nautique. Its a 1984 sn2001 with a 351 with a 1000hrs on it. I test drove it quickly before I bought it but obviously not enough.

The engine runs great - starts with a quick turn of the key, idles great and has great power out of the hole. It will run up to 4400 RPM without a problem. AWESOME!

However if I go above 2200 RPM for more then 2minutes (trying to pull a tube for instance) it starts to cut out. It bogs down, no backfiring drops a few hundred RPM and then will catch again....if I pull it down to an idle then I can take back off again without problem. Then the issue will reoccur. It seems to be fuel related because the higher the RPM the shorter it last without an issue.

So I pulled Fuel/Water separator out and replaced cartridge with a new one. checked the vent tube from gas tank and it's clear. I also have the old mercruiser style fuel pump, the one with the filter on the bottom of it - when I pulled it open there was only a spring in there with 'junk/rust' at the bottom. not sure if someone pulled it or it disintegrated over time??? Anyway I replaced it with a new one.   Also the strainer going into the carb was clear of debris.

Also the boat has electronic conversion on it so there are no points, cap and rotor look to be in good shape.

Any thoughts or where to start. I'm guessing this is still fuel related (pump?/clog on intake tube in gas tank/ or Carb? (has the 4160 holly) OR spark related (maybe coil?)

Kid's can't wait to learn to ski ----- Please advise!

Thanks for your thoughts in advance......
