That'll do it,

[Mr Proach]

This explains why the port engine was running slightly warmer than the starboard! We were lucky that the boat was lifted for a hull scrub and some other jobs, I'd put the 6 degrees difference in temps down to a heat exchanger needing cleaning having checked everything else. It's amazing that any cooling water was getting through at all.

Do you have a see thru seawater filtering the boat? Could you by any chance see a difference in water turbulence from the intakes?

Yes, the sea water intake filters are clear and I hadn't thought to check for differences in turbulence, but would it be that noticeable?

I do not know , that is why i asked as i am curious to know if it can be detected form there

good point, I don't know. I guess a flow meter on the intake could be useful for comparison between the two engines, measured against what, I'm not sure other than T's & P's. The only other way I can think of would be a visual inspection but thats not always feasible or possible. A through hull dome camera could be useful in a range of circumstances but it could also be an unnecessary hole in the hull!

I have vetus water strainers with clear lids so after a few problems with one engine not priming after winterising I put a few plastic balls in each side so it was easy to see if water was moving straight away, had to buy a kids game from a charity shop for the balls though as couldn't find anything appropriate otherwise (can't remember the name of the game but these balls have eyeballs).
Works well but could do with a deflector on the inlet so they spin better when pumping.

MAN ,tend to measure quite a few things inc coolant" water pump pressure "

It alarms
Minor -just to tell you it's outside of normal parameters -but rpm continues -it's your option to investigate .
Major -drops rpm to 1200 -- but you can continue if you wish .
Imminent potential damage -shuts it down to save its self --in threoy ?

The faults /alarms are storred in the memory -you can erase ,or it let's you erase when it's running back as normal .

It also differentiates a sensor error and tells you ,if there's a duff sensor -usually a pulled plug /wire .

So if you were to accidentally unplug the "water pump pressure " after clumsily clambering around in the engine room - next time you start up it tells you -throws a "sensor error ." "water pump pressure " or what ever it is

All msg ,s are in plan English on the screen ---no light codes .


We have 4 screens in all inc coolent temp and pressure -so can determine when the heat exchangers need doing .

I think the MMDS is a bit underrated .I,ve found it a friend .

Buts that's the Germans for you --think there cars

What's causing the pattern of growth around the skin fitting?

What antifoul is it?

What material is the skin fitting, how well is it bonded to the anode?

the boat was lifted for that very reason, the growth was 100 times worse as it was originally in SCR, it had a quick clean but some areas were missed. the boat is coppercoated, apart from the through-hull fittings. That has been rectified today after a significant cleaning job. the fittings are standard brass and well bonded, the last survey, a couple of weeks ago showed a nice bond.

I must admit having plain English warnings would be nice, the diagnostic buttons on my VP's do require some decoding which is less than ideal. Incidentally, the coloured discs on the engine control buttons on the FB have perished and cracked off, anyone know where to get replacements?

Brass?
