I know that this is kind of an open ended question so please bear with me.
I picked up an 89 Evinrude 150 on an 1850 center console Stratos.
I took it out on the water the other day and it didn't seem to be pumping much water out the visual indicator tube. It increased if I increased RPMs so I got it on plane without too much trouble. After a minute or so, the alarm started intermittently beeping. I took it back home and dropped the lower unit to replace the water pump. Since the boat has an unknown history, I figured that it was cheap insurance.
I also pulled the thermostats and flushed water back through the motor from the top down and the bottom up. Everything seemed to flow well. I replaced the thermostats and the water pump last night. It did take a second try to get the shift rod adjusted but once that was complete, everything buttoned up nicely.
We took the boat out again today. The water pump pressure was much better. It popped off a line in the cowling that fed into the siphon tube. There was also good pressure to the temperature gauge up front.
So, I have good water pressure. The temperature gauge shows in the middle. The motor isn't generating the RPMs that I would expect. 4600 or so with a 14.5" x 19" prop. And I get occasional alarms.
Someone removed the VRO injection from the motor.
What alarms are there on these motors? And what is the best way to track them down?
I still have to do a compression check on all 6 cylinders and check for spark. I'm just trying to get a game plan to track down the warning.
Any help is appreciated.
