I would start by checking you battery to see if it's close to 12.7V without it being on a charger for 2 hours. If voltage is good look at connections to see if they are clean and tight
edit: changed 13.7 to 12.7
Welcome
Needs some clarification. I looked up 2004 Tuffy Esox boats and the heaviest one was a 20 footer at 1500 LBs. A boat this light should not take a lot to load.
Please help us understand the issues?
ok, than your rebuilt carb idle jets are clogged up.
You get fuel when you pump the carb, so you should be able to keep it running if you pump the throttle a little (back and forth) to keep gas going in.
Did I read you correctly? It will start with pouring gas down the carb but not when fuel squirts from the jets?
If that's the case you have bad fuel in the tank
Welcome
Happen to have the motor serial number?
Being a carb and what your saying I'm still thinking fuel, but could be something is getting hot just sitting
If you can put a fuel pressure gauge between pump and carb. You should get 4-7 psi from idle to WOT.
Could also put a vacuum gauge...
Part number 8M0068784 is the oil pressure sensor, an I'll bet a beer it's not you problem. Those 4 in 1 gauges are crap and don't last. The oil pressure gauge is not connected to the ECM, another sensor is used for that
The speed not working is most likely the pitot tube is clogged. If you have...
The EST system is pretty simple and would not be the first time a new module was bad. The problem with EST is there is not a great method of testing to determine what is wrong.
Testing of system
Go fast boats use thru hull pickups often. So long as you install it correctly should be no issues.
Would also need to block off or divert
I believe yhou can still get the fittings your looking for @Scott Danforth can advise
