I would start with the carbs. Buy new carb kits with float for each carb and clean and rebuild them then change the fuel filter before starting it back up.

On some boats there is a manual handle to direct water to either wash down or livewell. If you hear a pump running, but no water in livewell, look for that manual handle in the hose plumbing.

Not knowing the engine manufacturer and horsepower it is still one of two items. Most of today's engines have an automatic oil feed if it is a two-stroke engine. The four-strokes have something similar, except it deals with maintaining a constant oil pressure for the engine and recognizes a low oil condition as well. Another potential issue is a restricted fuel supply going to the engine. Larger engines obviously, require more fuel. An air leak into the fuel line or a fuel restriction between the fuel tank and the engine can also cause alarms to activate.

Make sure you transducer is sitting level with the bottom of the boat. Follow the transducer cable down the line from where it plugs into your unit. There should be a tag on the transducer that says which model the transducer is. Go into "setup" in your settings and make sure the correct model of transducer is chosen.

Motor Guide Wireless Remote Pairing.
To pair a new remote, disconnect The trolling motor from batteries and re-connect. Then, within 10 seconds hold the + and - buttons until you hear a long beep indicating the remote has been paired.

I have one the New 115 Thrust and had the same problem.
This will correct your issue.

Go to settings and either change the depth using the icon DownScreen/Down Imaging and turn off. Or go to com and follow Doctor Sonar on Facebook and read the tutorial articles on understanding sonar. Or google doctorsonar.com

Yes you reprogrammed your unit to bottom depth.
Go to settings and use the arrow buttons until you get to the top of the unit. The menu will have several different settings you need to change the sonar settings. After you play around with all the different settings you will see what I'm talking about.

Join the Facebook group 'Everything Boston Whaler'. It is the best resource, Jeff Rohlfing is the owner and personally vets every member. Tell him I sent you. He knows every model like an encyclopedia. Also 'Continuous Wave'.

I am pretty sure the only Jet Boat was called the 'Rage' and produced from 1996. The EBW group has a section called Files and a PDF lists models and years.

You need to start at the simple stuff. Check the spark plugs and see if they are wet with gas. If not, could be a fuel pump issue. See if the plugs are fouled, change them and check for spark. If you have both, it should at least sputter. Check for water in the fuel.

Seems like the sonar isn't connected. Check the wiring to the transducer to make sure it is all connected.

That's great you have a 70 lb trolling motor. Do you have a question?

Boating | Answered on Sep 21, 2019

That's most likely a freeze plug that needs to be replaced by a new one.
