Looks like you got a recommendation on paint. I would have said any marine enamel if the prep. is done well.

I thought I used Vetus marine exhaust thru-hulls but could not find a link. They were a PVC flanged fitting that the hoses connect to nicely. The original tubes were just glassed in and I thought the fitting was a better solution.

My boat had new power (MP350) a few years back but all the surrounding components were still original, including the fuel tank, not a good approach. Once the engine and trans. are out and everything is opened up it's the time to do packings, hoses, valves, thru hull even the cutlass bearing and get the shaft checked and straightened.

The day I do repower I'm going for the white bilge, seen enough machine gray.
