Issues at 2000 rpms

Had the 94 190 (LT1) out this weekend for the first time this season.

Boat started up right away and sounded good. We idled out for a bit from the launch and then headed over to the other side of the lake to start footing.

When pushing the throttle down, motor would max out at 2000 rpms and only in the 20s for speed.

Got to other side of the lake, set up the boom, etc., restarted the boat and all was good.

At the end of the day, coming back to the ramp, same thing...throttle all the way down but tach maxed out at 2000 rpms and speed in the 20s.

Not sure if it is a throttle cable issue or maybe a fuel filter?

Otherwise, the boat performed without any issues.

My first thought is fuel filter. Check the one on top of the tank as well, or the always popular screen on the bottom of the fuel pump.

That sucks to hear on the first trip out!

T-stats correct? 142 and 160 with hole?

The boat worked fine when anyone was behind it!



The temp gauge was showing 140 or 160 all day...no issues...but I will check the T-Stat tonight...


I will check the fuel filters...I do not believe there is one above the tank though...when I pulled the tank out to drain it and clean it, I do not remember seeing a filter there.

So there should be one inside the tank then and another on the back side of the motor correct?

I didn't have the first filter on top of the tank....only the one in the engine compartment. I just added an in-line filter just after the tank and before the fuel pump. If I recall, the gas goes from the tank, to the fuel pump, to the filter. That's why we get debris at the bottom of the pump screen. Give that a cleaning first and then an in-line one on top of the tank.

No filter within gas tank other than just a screen at the bottom of the pickup tube.

Main Fuel Filter – Napa FIL 3481
Tank Fuel Filter – Napa FIL 3482

I'd even question prop/hull fouling if those numbers weren't so specific, my experience with fuel is that the boat falls on its face then catches again, if it holds 2000 even I'd be checking ignition.

Alright 88, now you are getting me worried...what are you referring to as prop/hull fouling? Not quite following you...


What should I check for ignition? I pulled the dash forward to install new depth guage but did not touch any other wires...everything was good and tight.

It sounds like it went into RPM reduction mode.

x2, I'd say something was telling it to go into "limp" mode. Check the engine codes, see if anything is stored. Otherwise bring a code reader with you and if it does it again plug it in and check it. Could be just a bad temp sensor or something.
