This was easier than I thought.

Bilge was pretty clean after the absorbant mats sat for a week... The banjo bolts for both pipes came off easily. I had to remove my raw water intake tube as it was blocking access. The shorter lube pipe had some surface rust along some of its length, and at the port banjo fitting closest to the water pump. But there were no holes. The longer pipe was the problem. As others have said the water seal in the pump fails, causing it to leak, the it drips along the engine until it hits the retaining clip for the longer pipe...that causes water to then drip down the tube. The new pipes arrive unfinished....For the longer pipe I painted with primocon primer and a couple costs of rustoleum...what i had in garage at the time. I plan to cover the pipe with some left over rubber hose. I also did not install the retaining clip i have to clean it as it was still rusty....will reinstall later...for the shorter pipe i smothered the exterior with lancote. Banjo bolts were torqued down to 150 in-lbs. I read somewhere that the if the water pump seals fail on these engines, the pump is designed to leak...not sure if this is urban legend or for real... at any rate i am going to watch that pump like a hawk....and i may stick on some kind of small "dam" just under and to right of the pump on the lower engine block in hopes of diverting any leak straigh down...not sure how to do that... i kept old part as i may go to a shop and see if the can weld new pipes to the banjo fittings as a backup, or simply use flexible break hose or the like.... Ran motor for about 20 min....no leaks..tomorrow i'll see if there is any leakage. hopefully i'm set for a few more years.... Next job after mid Oct haulout is new cutless bearing and dripless stuffing box! That job might be a bit more involved... --- In s227classassociation@..., Bob Taylor <woodwork@...> wrote:
