Hello,

Mariner 4hp are identical to Yamaha engines.
You should find a sticker on the port bracket with serial and model number.
If that sticker has disappeard, an aluminum piece is stamped in the side of the cilinder. The numbervstamped in that round pieceis the serial number. I can convert that serial number in a year/model number...

Hello, is it the external shift handle you want to replace?

Then you'll have to remove the engine block from the driveshaft housing.
To do so: Drain the engine oil.
Disconnect the throttle cable from the carburettor.
Disconnect the start-in-gear cable from the recoil starter housing.
Disconnect the fuel lead at the fuel connector
Disconnect the choke puller at the carburettor.
Disconnect the white and black wire from the stop button at the engine-block and engine wires.
Remove 6 bolts holding the engine-block to the driveshaft housing.
Lift the engineblock.
The shift lever is fixed with a M6 bolt in the front-top of the driveshaft housing. You'll need a new gasket, Part Num 803508-9

Good luck!

If you are really interested, check to see if a library has this book : Chronometer Makers of the World by Tony Mercer. It should have info on the year of manufacturer.

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
