All,
First let me say thanks to everyone who has helped me through the water pump replacement and the whole bellows job. I am not sure if anyone else has ever done this, or if I did something I shouldn't have, but to get the U-joint bellows clamp on the gimbal housing side tightened, we drilled a hole in the gimbal housing like the one that is on the other side for the exhaust bellows. Anyone else done this? The shift cable bellows were tough, but manageable. The exhaust bellows on the gimbal side get in the way! The exhaust bellows themselves were quite easy I thought, even without a tool.
So, to my next question, after putting the outdrive back on, which was a PITA itself, the last 1/2 inch or so of gap closure was a chore without using the bolts/nuts to pull it on, we verified that the cooling water pump was getting water to the HX, FINALLY. I expected the cooling water and exhaust to all come out of the prop, but most of the water (that not leaking past my earmuffs) was coming from the gimbal housing. Some was coming out of the prop, but not alot. I thought at first the exhaust bellows on the gimbal side were leaking but we verified (getting quite wet in the process) that this was not the case. Next, I thought it was the water xfer tube connection on the gimbal side, but then the water would be cold, whereas the water leaking out was warm, so it was definitely coming from the engine and HX.
I have read mention of weep holes. I do not know where these are though. The thought I had was that when in the water, the holes the water is currently coming out of will be under water with some hydrostatic backpressure, where as the area behind the rotating prop will be low pressure and provide suction, so the prop route will provide the path of least resistance to flow when the boat is in the water, and most of the cooling water will go that route. Is this a correct assumption, that with the muffs on out of the water the cooling water exhaust route is different than "normal" operation?
Sorry for the long post, wanted to be descriptive...sorry if this is a repeat of old questions! Will try to post a video link soon.
