Hello all,
So I started the generator yesterday and it was not sucking water and there was no water coming out of the exhaust. I had replaced the impeller two years ago after it disintegrated and it basically has less than 1 hour of runtime on it since then. So I took off the impeller cover and as I suspected, the impeller looks fine...all blades are there and intact. So then I bumped over the starter, even starting it for a second or two. The impeller did not move.
After a bit of research, it looks like my coupler has broken. In looking at the parts list on page 20 is looks to be item # 20, Part # 359448.
Does this all make sense, and am I on the right track?
Now my big question is: How the heck do I get access to this coupler, with the generator in this boat?!! Here is a photo I just took of the assembly:
Looks pretty nasty. This is taken looking forward on the starboard side of the generator and boat. To the right is the holding tank. Note that there is only enough clearance to remove 1 of the 4 bolts.
With the 4 bolts loosened on the housing, should I be able to remove the impeller and then remove this assembly? It looks like I'm seeing two parts there. A brass piece covered in a green patina, and a steel piece behind it that is all rust. Where is the coupler? Will I need to remove this steel piece too? There looks to be 2 allen-head bolts holding it in place; 1 I can see, the other I can only feel. I'm worried of their condition too, to be able to loosen them.
Has anyone done this before, in this boat with the minimal clearance? It's crazy how when they installed everything, they didn't leave enough room for the bolts to be removed, arghhhh.
Thanks,
Tom
