Just a bit of feedback:
After removing the oil cooler and stripping it to check the two o-rings, I moved on to strip the raw water pump
down and found weeping on the waterpump sealed bearing seals
.... Seems that this is where the salt water
I cheerfully went off the Yanmar
agents in Cape Town
and was horrified to learn that a wholesale replacement w/pump was $1411 ex vat! Seems these guys usually deal with International shipping
companies needing genset spares and wait like spiders for an unwary victim to attach himself to their net. Local Yanmar
owners have no choice but to buy at cost x 10 x10, as they are the official agents in Southern Africa
. Interestingly, I managed to find a fellow yottie by the name of Graham Raynor, who has a little pump company in Cape Town
called "Pumptech" and Graham rebuilt the whole pump, using locally available spares at a fraction of the cost ($211.00). Thanks Graham.
I absolutely detest opportunist agents, so I guess I'm going back to Nanni or marinised Fords and ditching this revolving lump of scrap iron/aluminium, soonest. Goodbye Yanmar.
