    Raw Water Pump Shaft Leak

    I have an '86 E-28 with the M12 Universal. I replaced the impeller on the Oberdorfer raw water pump at the beginning of the summer, and had no problems. However, today I noticed a water leak coming from the seal where the pump mounts to the engine. I tried to tighten the 4 cap screws, but...

    Raw Water Pump

    I have the Universal 25XP with an Oberdorfer raw water pump. Does anyone know which direction the impeller turns? Looking at the impeller, does it turn clockwise or counter clockwise?

    Raw Water Pump Leak

    Hello All: Have just noticed (during a 4 day trip) an accumulation of dried salt below the raw water pump on our Universal 5432. I assume it is probably a seal/gasket issue where the pump housing attaches to the engine block. As we are getting ready for a 3 week trip, I want to eliminate any...

    Raw water filter

    I just discovered that my recently purchased 1988 E-32-200 has no raw water filter for the diesel cooling system. In the Southeast USA when the water warms up people find gook, algae and even little crustaceans in their raw water filters. Is this usual for Ericsons not to have filters on raw...

    Raw Water Cooling M-25XP

    Has anyone put together a logical sequence of attack to identify blockage on the raw-water side of the mx-25? Is there a schimatic out there?!! Water flow through the exhaust stopped abruptly on me yesterday and so far I have: 1. Blown out the water intake line (with my air horn, and...

    Raw water cooling problem solved.

    All, I'm posting this in the event that it might happen to you. I was baffled for a short while but now that it's over, it all makes sense. OK, here are the stats. The engine in my E31 is a 22.5 HP, 3-cylinder Yanmar 3GMF, the F standing for fresh water cooling. There's a round, bronze Buck...

    Raw water failure alarm

    Spotted this in Passagemaker and ordered one for Journey. Simple installation and should reduce the amount of time spent leaning over the stern checking for water flow. www.borelmfg.com

    Universal 5432 raw water impeller kit/part#?

    I disassembled the raw water pump today to replace the impeller. The part number, IIRC, Westerbeke 33100 is not the correct impeller. Both the manual and the other spare on the boat were also 33100 so I am confused as to what pump I have and why the PO would have the incorrect part and part...

    Can I clean raw water intake screen without...

    I want to do a preventive clean/empty the raw water intake screen/filter on my Universal 5416 motor. I think it just unscrews, then the screen is accessible to clean of any debris, and then reattach. My questions are: 1) If I close the raw water seacock, is there any other source of...

    Sherwood Raw Water Pump

    I have been doing some reading on the raw water pump (oberdorfer) that is on my Universal M-40 and see that there is a Sherwood replacement with significantly higher volume output. In running engine at WOT I noticed the temp run up to about 200 and thought that a bit too high. Running at...

    Oberdorfer Raw Water Pump Wear

    I received an email from O Barquinho's new owner, Erwin - who took OB to Alaska this summer. He had an issue with the raw water pump not priming, and subsequent overheating of the engine. He sent an email outlining his fix, and it's the 'Racing and Cruising' forum. There's also a nice...

    Attached is the promised picture of our new raw water strainer (Groco ARG750) that I recently mounted underneath the sink of our E34. Sorry it took so long to post this. Chris E34 Dangriga

    Raw Water Strainer

    Reading a thread on Sailnet about strainers, it dawned on me that my 1988 E28 doesn't have one. Is this a desirable add-on for this boat? Thanks
