    expected raw water flow rate on e34-2 / m25xp ?

    Does anyone know what the raw water flow rate should be on m25xp? (with oberdorfer pump)? Has anyone measured it (at different rpms?) My engine is running on the hot side and I'm troubleshooting.

    M25XP Corrosion - How bad is this?

    Hello, I'm a happy owner of 32-3 since this spring and this is my first post on this forum. This is a great site and I was able to find answers to all my questions so far. On Sunday I had some time to take a closer look at the engine, and found corrosion around the raw water pump. There is...

    Fixing Temperature Gauge on Universal m25xp

    My temperature gauge is busted, was busted all last summer. Promised myself this would be resolved before I go back in the water. Does anyone have a link to a good article on the trouble shooting steps to be find the problem? I have never looked at this part of the diesel system and have no idea...

    Name this part - my Universal M-25XP

    It's just embarrassing that after 3 years of ownership I am just noticing this but you know what they say. I always say there are no stupid boat questions, just clueless owners (like me). There is a hose dangling down the right hand side of my motor that is releasing exhaust gases into my engine...

    Universal m25-xp heat exchanger which model?

    Does anyone know for sure which heat exchanger from Seakamp can be used to replace the one on my Universal M25-XP? The interweb provide conflicting advise. Seakamp wants a picture of it. Of course it's 5 hour round trip to where my 1989 Ericson 35' Mark 3 lives so will not have a photo before...

    E-34 Universal M25-XP water pump

    Looking to replace fresh water & Raw water pumps on my M25-XP. KKMI boatyard told me when I had it in for haul out that they would either have to take the front of engine apart or pull the head to replace fresh water pump. They suggested pulling & R&R head which will cost big $. Anyone have...

    Wanted M25XP

    I have a Universal 25XP with one weak cylinder, it doesn't puff until 2400 rpm then it puffs realy bad. There is blow-bi in the valve cover at all RPM's. What is the best way to figure out if it's rings, or a valve? I don't think its a head gasket as it doesn't overheat. Any sugestions would...

    M25XP hose size from coolant pump

    On my 1989 Universal M25XP I still have the original hose on there and want to replace it - but I recall the hose has different size ends. One seems to be bigger than the other. Mine is a short hose, about two inches coming down from the pump, a 90 degree turn towards the side of the engine and...

    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...

    Universal M25XP Oil Pressure Sender

    I have a Universal M 25 XP engine. I started the boat this weekend to find that the alarm buzzer for the oil pressure is not working. Changed out the buzzer but still nothing, so I'm suspecting the oil pressure sending unit. Looked around but couldn't find it. I suspect it's hidden...

    Rebuild Universal M-25XP...

    Howdy folks, Finely got the paper work on boat (E-34-2 1988) here in Nicaragua just in time for the SW storms & swells and storms. Now that things have lightened up a bit it was time to start the engine and have a go at the coast. The start up went bad as the starter battery was 5 years old...

    Motor Mount replacement: M25XP

    We are about to do some serious fall maint. and one of things on the list is reducing the vibration from the engine. My contact at the boat yard advises that 18 years and 1700 hours of run time would indicate that the original mounts are hardened and no longer doing much to dampen vibrations...

    M-25XP Fresh Water Pump

    This past Sunday, cranked up the diesel and heard loud squealing. The belt was running over the fresh water (coolant) recirculating pump which wasn't turning. Tried moving the belt by hand several times, and the pump would move and then seem to hang up. Tried restarting a couple more times...
