I would snip the limiter...it's not likely your issue but it will eliminate the possibility.

Do an OHM's test on your plug caps. They are a known weak point on those motors.
Make sure you've got good grounds...that computer is sensitive to proper grounding.

Check your fuel system for shit and loose connections/restrictions. The connector in the pan is gone right?

Don't free hand the tps...you need the harness and a meter to set it correctly.

i will un plug my limiter,

will new ngk plug caps be a good idea?

fuel system is clear but im going to open up the carbs and check the jets, it idles so good and doesnt fart or cough or sneeze so i doubt their dirty...

i have an electric fuel pump i can hookup too it too see if that helps. iv heard the mechanical ones suck even if there new..

saw a pro v last week with a electric pump AAnd mechanical pumps should i delete my old pumps or just do what that guy did and slap a pump on it too test it..

i haven't touched my tps ever. i might need help checking it out..

and what about t-stats is it over heating and going into limp mode i don't have a temp gauge. :s

New plug caps would eliminate any question...but testing them may tell you you've found a problem.

The mechanical pumps seem to work fine on mine lol...I'm not saying you don't have an issue with one just that they work fine when they're working (yours are 25 years old lol)...if you want to try an electric pump you can run it with the stock pumps in line.

I can check your TPS no problem.

Overheat would buzz and knock you back to 2000rpm....like running low on oil. You can't miss it lol...you won't be on plane and the control box will be screaming at you.

I also have a complete set of excel electronics if you want to try any bits..

how bout an alarm i think i need a wire from the power head too the harness. for the alarm

im also going too james cole it and run it with the cowl off. just so i can see if the oil bottle on the motor if going empty, when i stop i can hear it filling. do the pumps in the oil tank get weak or just stop working

If your tank was going empty you would not be boating lol...it's a one time deal. If your main harness is attached and you have a factory control box (and all of your grounds are attached to the block) it will beep when things go bad. The oil transfer pumps last forever if you don't try and pump water with them. The only time I've seen one not work is when they are not plugged in. Definitely not a bad thing to check but it's not the cause of your miss.

stop fucking around boomer. throw some fresh 91 in it and take it to Dok for a TPS adjustment.

im running on fresh 91... the only time i run on anything but is when i have too use a random gas station that claims their 6 month old 82 octane is 91

doesnt the alarm go off if the tank on the motor gets low before its empty .. what color is the alarm wire dok.? their is no brown wire coming from the block but its in the harness. so what ever that is its not hooked up.

im 90% sure its a fuel delivery issue, ill check everything i can myself and when i get a day take it too MRS for a go over

say the tps was out would it take wot down low... i can hang onto it too the floor for a bit and it doesnt stumble just up top @ wot.

Brown is the start relay usually.

The buzzer will go off once the tank on the engine gets low. Then you hold the toggle switch on the side of the motor to transfer the reserve into the little tank...at which point you have half an hour of wide open running. none of this will cause your surging...

It's likely fuel delivery or a high speed ignition break down. Make sure your fuel pickup is clean and the anti-siphon valve isn't plugged...good fuel hose and primer bulb..etc..
