Gushing water near grease cup
Here we go again. I'm very new to this engine and engines in general, but I'm trying to learn. So far everyone here has been so helpful. Thank you!
I went out yesterday and after reinstalling the thermostat, replacing the spark plugs, etc, the engine started right up. After checking for leaks, I found this There is a steady stream of water coming from just forward of the grease cup. I've attached a picture from the video I took. You might be able to view the video here: https://drive.google.com/file/d/1f6M...ew?usp=sharing Any insights and help would be very appreciated! Thanks! Matt 1975 Sabre 28 |

The only source of water in that area is from the pump body itself and is making its way out via either a damaged shaft seal or a freeze crack. If the budget allows this would be a great time to consider a new MMI 502 flange pump.

When I feel back there, it feels like there's an opening where the water comes out that is an actual opening and not a crack. Does that make any sense? Is there an opening right there? |

Yes, the Oberdorfer 202M, the pump you have, has an opening in the casting on the bottom for the specific purpose of letting errant water out. There shouldn't be any water in that area to begin with.
If the pump housing is not cracked, the 202M can be rebuilt up to a point. The time will come that the impeller cavity is so worn that pump performance will fall off at which point you'll be buying a replacement anyway. Like I said, you can get out ahead of future repairs by replacing now.

I'll try to take out the old one and buy the new one. I'm sure there's a thread around here somewhere about this, but can you tell me, is it just those two bolts to remove it, along with what looks like two connections to the water?
Those bolts seem like they might be difficult to get to. it was hard enough just getting the camera back there. But I also see on my video that there's some kind of create-a-gasket residue on it, so it has been done before. If there's a trick to it besides a wrench, some PB Blaster, and brute strength, I'm interested to know! Thanks so much for your help! |

Two bolts and two hoses, that's it. While your credit card is handy, consider MMI's extendo-bolt that was specifically designed to remedy the poor access of the bottom bolt.

The lower one is notorious for being hard to get at. Because of that, many of us have the Lower Extended Bolt sold here by our host. EDIT: Neil was faster on the draw...
