I installed one this spring and was very happy with the quality of the casting.
It's an exact copy of the original Yanmar, including the 1 1/4" BSP thread on the outlet. Grocco makes a 1 1/4 NPT to 1 1/2" ID bronze hose barb that seems like the the perfect adaptor. Unfortunately 1 1/4" BSP is 11 threads per inch and NPT is 11.5 , so when you thread the barb into the elbow it turns in about 3 turns and jams. BSP is straight, and NPT are tapered as well. If you can find a barb with 1 1/4 BSP threads, you would be able to snug it down properly. I discovered this in the yard and didn't have the time to hunt one down, so the Grocco one is in there now, but I will replace it. I was going to contact HDI Marine and see if they have one.
