I've tried emailing Beneteau
and two Yanmar
dealers to no avail (none of them have replied in months), so I'm reaching out to the forums
for feedback/advice: there's nothing on the subject in either the operations or service manuals
P.O. changed the engine
(Yanmar 4JH3-TE) and gearbox
for a new one around 1200 engine
hours ago. This only came to light when I realised the existing hoses coming out of the calorifer of the hot water
tank had been chopped somewhere in the bilges, and the hoses not reconnected to the new engine.
I'm thinking of connecting the calorifer into the engine just downstream of the fresh-water pump on the front of the engine, using the same hose-bore-diameter as already exists on the engine (see below sketch with red pointers) with the shortest lengths possible to reduce additional flow-resistance.
The only photo
I've managed to find that appears to show the hook-up locations is this one:
Which would appear to tally with the following unused ports
on my engine:
I'm assuming here that these ports
'open' when a thermostat comes up to temperature, but again - i'm guessing here...
Any experience or feedback would be appreciated, especially from anybody who has a 4JH3-TE hooked up to their hot water
Thanks in advance,
