OK... I've got another thread going about a
raw water exhaust manifold rusting through in the
Maintenance forum... but:
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?
