We went out and water tested it today. I brought a funnel and a pump to be able to add/subtract fluid. What ended up happening is that when I pulled some fluid out to correct the over-fill, I was able to see a little water in there. So, I am thinking that there was some residual fluid in the lines to/from the tranny cooler that didn't empty when we disconnected it. Yeah, we didn't think about that until everything was all hooked up and re-filled. So, we sucked out all the fluid we could, refilled it with new fluid and then let it circulate a little, then sucked out all the fluild we could again, and replaced it with clean fluid. An on the water flush of sorts.
I'll probably attempt a better flush over the next couple days here at home. Any insight on the best methods to flush a transmission?
In other news, Looks like we got a good location to mount our in hull transducer though. I was able to get reads off it that seemed very logical with what we know of our river. So, we'll probably work on getting it permanently mounted soon as well. And it did seem like our prop alignment paid off.
We were kinda hoping that tonight would be a fun play night, but it ended up being a shakedown cruise. There was no way I was going to put any load on the engine when I found even a little residual water in the system.
