OK... I've got another thread going about a raw water exhaust
manifold rusting through in the Maintenance
I've just learned that there is a Yanmar
3GM30F in the boat yard here and has the freshwater cooling
system that (in theory) bolts right onto my 3GM30 raw water engine
block. I checked it out and it looks right.
Obviously I'd have to add the fresh water
pump and some extra stuff (but it's all there on the other engine) and it seems to be in working condition.
So here's the rub:
I could spend $700 (plus duty if we're unlucky) getting the new raw water
manifold and cover from the US and getting them to Mexico
(where we are on the hard) or we could try to do this conversion to freshwater with what's available (used) here for far less money
and perhaps is a better cooling
system? The new system is more complicated (an extra pump, more stuff to break and to check on) and I like the simplicity of my old system.
Add to that: we have a 2 year old and are in a dusty toxic cheap
boat yard and want to get away as quickly as possible (the new parts
will be at least 2-3 weeks).
Anyone had both? Pros ans cons? Would this be a a true upgrade or just a lateral move to something different?
