The motor on this runs fine, but when I started it there was no sign of any water out of the tell tale (the approx. 1/2 inch hold about 12 inches down in the back).
I read on Leeroy's site (I'm assuming most of you have seen it), and in other places, that water doesn't come out of this hole until the engine has warmed up (thermostat opens) and the engine is in forward gear, as this engine needs the prop push against the intake to feed the water.
Well, mine wasn't spitting any water at all, even when revved up in forward gear. I made sure the water level was well above the intake.
So, I did the first thing everyone suggests, and replaced the impeller. The one in there looked very good, but I replaced it anyway, cleaned things up, and reassembled. Still no water.
So, I took off thermostat cover. Thermostat had grass / muck in it, so I took it off and cleaned it up. Also cleaned up all the holes in the thermostat housing. None were blocked, but they were a little dirty so I scraped them out. Reassembled, started, but still no water out of telltale.
Took thermostat cover off and saw that there was no sign of water in there. That is to say, the "tray" or flat area inside, was dry.
Leaving thermostat cover off and thermostat out, started engine and put in gear. Expected to see water shoot up into the air out of thermostat housing. No such luck. A little dribble was about it.
So, I'm seeking help here. If someone can help me out either:
1) ideas to check next (a friend suggested maybe blown head gasket?)
2) how water flows in the thermostat area. If you look at the picture I've attached, I numbered the holes in the housing. 1 and 2 are obvious. 3 and 4 are covered by the thermostat, but let's say 3 is the small hole at the top of the thermostat hole, and 4 is the hole further down. In what order does the water flow between these 4 holes? That is, it comes in through the intake, then comes in what hole, goes out which hole, and when thermostat opens what changes.
Sorry for the long post.
