Mercruiser 3.0 - Aplha One - exhaust question

[TommyRox]

I have a 99 SeaRay Bowrider 180 and went through changing impeller due to some overheating issues but got that resolved. After changing the impeller and btw engine is running 130-170 like it did before, when I ran the boat in the driveway with muffs there was hardly any water coming out the center of prop.

I have only ran it like this a handful of times and cannot remember if this is normal. The water is definitely cycling and cooling but comes out above lower unit...nice and hot might add.

I didn't want to take it to the lake after the impeller repair until I knew this was normal. Any feedback would be greatly appreciated.

If she maintains normal opperating temp on the muffs then the next step is to put her in the water. As far asthe flow from the prop, most water and exhaust normally exits through the lower unit.

It begins to come out of prop center at higher speeds and when moving through the water. It sounds like its operating as designed.
