Gentleman/ladies I know there are years of accumulated experience out there and would like some help.
I've just bought a Crown 34 powered by a Yanmar 2QM15 that has at some stage had a sen-dure fresh water cooling conversion added.
When this was added it appears that the original over-temperature warning switch was removed and where the Yanmar service manual indicates the switch (and a zinc) should be has been replaced by a blanking plate.
This means I effectively have no overheat warning on this engine.
I would be grateful for advice and specific details as to how to fit a temp gauge (preferably third party due ridiculous Yanmar prices) and reinstate the temp switch connected to the warning light. I am not sure if there are spare ports on the engine block, if there are their locations and what thread size yanmar would use.
In a similar vein the original oil low pressure warning switch has been replaced by a pressure sender and gauge, again I would like to reinstate a warning light to run in parallel with the gauge but think that this would necessitate a "T" fitting, again are these fittings available and what thread sizes do I need, what make of oil pressure switch etc etc
Many thanks in advance for your input, James
