I was just referencing that they did use some sort of metal material in the line. I do have a heater though so I will be adding a tee. Main piece I need to make is for the offset piece from manifold resovoir to exchanger. It is the hose up front of engine.
I have a hose from the newer style manifold, similar but it’s a bit to long creates a kink. So I’m just going to plumb up a hose. It is a tight space in there so it would need to be a direct replacement or fit up piece with elbows.
I may or may not add Heater. There is an older red dot
that needs replacing. I just asked that question on general forum. Is it worth using on a merc 470? Create enough heat?
19 foot glasply will have canvas top for colder days.
I wouldnt use an external heater with a 470 as it has a heat exchanger and the expansion volume of the HX is marginal at best for just the motor. if the volume is low and you have the 4" HX, maybe
adding additional volume to the coolant means you need to add additional volume to the HX for expansion and draw down.
Ok, I do have the 4” heat exchanger if that makes a difference. What is better material to use for fittings steel/brass or copper? Maybe one is less reactive for corrosive reasons? Engine has aluminum block and steel head.
Used a couple 45s on a roll to get through alternator bracket. Was even faster than driving to town. Was nice something went smooth for once. Cut up hoses from old pieces. Most of plumbing was able to piece this way.
