I intend to drain and replace coolant/water and noted that in their manual they show the motor
volume only... not with the radiator/ hoses etc. I would appreciate anyones input as likely marine
total.... Also they recommend for tropical areas (venezuela) a ratio for coolant/ water
I have read previous threads recommending 50% and initially thought to go with this ratio of "motor volume" on the assumption that the extra water
would probably bring to 30% ratio. Then realised that the specific knowledge was available here in CF.
Further, there was an interesting thread a few weeks ago discussing whether it was best to allow the prop to be free or locked in reverse, while sailing. (it was suggested that the manual would recommend). Unfortunately the associated documentation
is in French and my French is not good enough.
However, I believe it is a "Borg Warner 72CR Reverse gearbox
Simple question does the "Reverse" in it's name indicate, that it should be locked while sailing and if so, what is the correct process of doing so?
Finally the rating is Circa 72-80HP (general manual) The marine
manual does not specify. vehicle is 80hp and heavyduty 72. I assume that a 17 ton steel ketch
is assessed as "heavy duty". It doesn't have a rev counter and the manual, depending on configuration provides a scale of between 2200 to 2800. I would like to know
As always many thanks in anticipation
