Oil alarm causing motor to throttle down

[WhitePerchHunter]

I have a 1997. 175. Runs great, still pushing my 18' Sprint 65 mph. The last two times I took it out, I get an oil alarm, then throttles motor down when I get to 40 mph. It will run all day long as long as I stay below 40. I changed the strainer and the oil pump on the tank. It might have helped a little cause now I can get it up to 45 mph before I get the alarm. I since then cleaned the large strainer in the holding tank on the motor. (The Yamaha dealer in town did not have a new one). Any suggestions on what to check now would be deeply appreciated. Thanks.

Are you finding the main oil tank to be low when the alarm sounds?

Check the oil line for a kink or clog.

With the main tank completely empty the pump will run when the key is turned to the on position. The main tank should be more or less completely filled in about three minutes time if all is well.

The main tank can be drained easily by removing the plastic sump at the bottom of the tank.

The main oil tank is 3/4 full. When I changed the pump, I drain the oil and check the tank for any trash. It was clean. The oil lines don't appear to be kinked. I may have to take them off and blow air through them to check for clogs. I don't think the oil injection pump would be the problem. Any more thoughts. Thanks again.

main tank is the one on motor, remote tank is the one with pump that pumps to the main tank
If main was not low the alarm should not be going off at 3/4

I know what Yamaha calls them.
for the sake of confusion QUIT.

call the dang engine tank the ENGINE tank and the remotely mounted tank the REMOTE tank.

see how simple it can be made?

repost your issue again using less confusing terms and I will try to answer.

remember all that stuff was a Japanese to English(jinglish) translation and it can be confusing.

what visual indicate do you get at the alarm condition?

If the one on the engine is the engine tank then why isn't the one in the boat called a boat tank?

Or, if the one in the boat is the remote tank why not call the one on the engine the non-remote tank?

Surely you are not expecting us to have enough information to semi-accurately offer a solution to an unknown problem?
