Thank you. I may have been on SBO at some point but I don't recall ever going to a Catalina site. Or maybe it spilled over from there into other forums?

Entirely possible. That's how misinformation spreads, people repeating what they read without any specific knowledge of their own.

In principle installing the new water pump should be very straightforward: just two bolts! It is a bit more tricky in my installation since I have the Indigo FWC system. The bracket that holds the raw water pump partly obstructs one of these two bolts. I will have to see how much disassembling this will require. |

Well, without the snap ring it's possible the shaft could slide out of the pump during transport but that would require it to be shipped in a box with one dimension over twice than what is necessary. You're right, it's a ridiculous premise yet the internet experts persist.

My first idea was to cut off the bolt but I thought I check with Tom Stevens before doing that. He answered again within a couple hours (!) and pointed out that I am already loosing about 2mm in length because of the thicker pump body. He suggested instead to grind down the pump body. Of course this made a lot of sense. So this is what I did. After that, everything went very well (OK, there are always things that go wrong: I actually overshot a bit with my grinding and as a result, the fan wheel of the alternator started striking the sheave of the belt, requiring repeated taking apart of the whole thing until I had everything back to where it needs to be). The pump is working very well now. There is, however, a new problem: I noticed a tiny weeping of oil at the flange. It is really minuscule but I do not want to have any oil going into the bilge. I tightened both bolts as much as I dared (and that is really very tight!) which made the leak even smaller but it did not go away. I was flabbergasted and had no explanation. I ran out of time and in the car on the way back I found a possible explanation: I had mounted the pump dry, using just the gasket provided. But the old pump had quite a bit of gunk at the flange, some goop someone (not me) had used with the old gasket. I realized that I had scraped that off on the pump side (in case I will use it as a spare) but not on the motor side! So I wonder if there is some of that stuff on there, preventing a tight fit. So I guess I have to take everything apart again and clean up the motor side of the flange. But before I embark on that project, I have two questions: Assuming that my idea is correct, that there is some dreck on the flange, did I ruin the new gasket? Should I pre-emptively order a new one? And second, I mounted it dry. Should I put some goop on the gasket when I mount it again? Thanks for any advice! Last edited by ernst; 10-28-2019 at 06:03 AM. Reason: typos |

You didn't have to, that's why we are here. I wish you had mentioned the earlier advice on the forum before reaching for the grinder though.

Does that make sense? If it does, do I need to order studs somewhere, or can I just cut off pieces of suitable length from a threaded rod? I may even have one (stainless) lieing around, have to check when I get home. And I suppose the studs need to be installed just with a drop of oil on them, right? Thanks for your advice. |

Be sure you don't thread the studs too far into the accessory drive. There are moving gears in there and you don't want to engage them. Rather than oil you might consider Loctite.

In the lower right, near the gear, you can see the backside of the lower pump bolt. The last pic gives you an idea of the thickness of the threaded area for the stud/bolt.

Thank you, Neil and Jerry. Something else I hadn't thought about!

Situation update: Yesterday I took out the pump again. Of course that included removal of the alternator bracket, which means moving downthe alternator. As expected, there was old gasket material on the flange. After I cleaned that up and installed the new gasket (requiring a trip to the hardware store since the lockwasher on one of the bolts was donated to the bilge), the oil leak is gone.
Whether my whole problem is solved is not clear. Before I started the above-mentioned work, I noticed that the bilge under the motor was again filled with about a half gallon of what looked to be at least partially coolant (no, I did not taste it, I have my limits!). I had not put in a diaper this time, precisely because I wanted to see if I might have a leak somewhere. Nevertheless, I did the multi-stage refilling of the block and heat exchanger, I am getting pretty good at that , and increased the controlling temperature slowly to 180deg, as prescribed. All went well but when I checked again today, to my surprise the overflow/expansion container was completely empty even though I had filled it to the brim yesterday (by mistake). I was expecting that the motor would have ejected some coolant when it cooled off, leading to an overflow of the expansion container but it looks like the motor sucked in its whole contents! No idea what that means. Unfortunately, when I was done I had to winterize the boat for the season. We will have a cold snap this week, with 36 hours below freezing (down to the teens). I have things set up so that winterizing is not a big deal so I could presumably go for a last sail next weekend but I am really busy at work so most likely this is the end of my season. I guess I won't know if this is the end of my saga or not until some time next April. Again, thanks A LOT for all the advice and hand-holding. I will for sure keep y'all updated once I emerge out of hibernation! |

Many moons later (Covid related): I believe the mystery is solved! The resolution of the saga is posted at the end of a seemingly unrelated thread, on painting the motor: https://www.moyermarineforum.com/for...t=11215&page=2 Cliff notes version: There was a slow leak at a completely unsuspected location. It was discovered by SASTANLEY on this forum when I proudly showed my 'after' pictures of the paint job, and he pointed out that in one picture there were some drops visible on the top of the block. Sure enough, that was it! I am extremely grateful for his eagle eyes, I would have NEVER suspected this cause! So of course I am very happy that this saga has come to an end, with a good solution. And I have learned a lot! The only possible negative is that I may have junked a perfectly good coolant pump. Well, it is still there, I guess I should order the snap ring (one of the things that I learned is that this is needed!) and keep it as a spare. Again: Muchas gracias for all the great input! |
