Re: No sea water to Motor
I have the same motor/drive and have an airleak on the outdrive. Muffs and buckets don't work for me either. BUT, I just disconnect the small (about 8" long) hose, that connects the copper water pump hose to the chrome outdrive hose, from the outdrive and stick the hose in there and clamp it down. It works great. Just don't turn up the water too high, and turn it off when the motor is off.
I found my leak by doing the opposite and hooking the hose to the chrome pipe side and back flushed the outdrive. It was easy to see where the water was leaking from. Luckily that spot is underwater in the lake and so it has no problems on the water, just in the driveway.
If I could just find a 1" flush tee to put in that hose, well that would be awesome.
