Last weekend I picked up a 2007 250hp Etec to repower my 1984 Outrage 22. It is mounted to a shipping crate, so I was able to stand it up and rig it for trial before I mounted on my boat. Last night I was able to fire it up, using both the muffs on the intake, or the flush port. Neither way was I able to get water to come out of the telltale on the back of the engine. I did have water coming out of the hose for the water pressure gage, and I did tape off the low water intakes on the front of the lower unit ( I was told this had an upgraded later model "Magnum" lower unit).
Without water coming out of the telltale I never let it run more than 30 seconds or so. I have a video of the engine running before purchase, but the telltale is not visible. I am also told that the seller put a new impeller in before I purchased the engine. Is there anything i am missing in order to et water out of the telltale?
Correct, negative results both times. Tonight I am going to try cleaning the telltale, i was getting water out of the exhaust as well, so SOME water was flowing through the engine.
Interesting that my service manual states that the engine may be run at idle only until operating temperature is reached using the flush port. There seems to be conflicting literature regarding this.
Regardless, that is why I only ran it for 30 seconds or so.
If needed this weekend I will drop the lower unit, I have had an instance (on a different engine) where an impeller was installed with the fins facing the wrong direction, the telltale was still functional, but weak and sporadic. I am curious if this maybe the case.
Well, I am an idiot. I didn't realize that the flush port IS the telltale. I thought it was the port above, which is part of the exhaust.
I made sure the fitting was clear, and hooked the muffs back up, I made sure they were properly sealed, and I had no issues getting water out of the telltale after about 10 seconds of running.
