    Just to confirm fuel/oil mix on this 1958, does it use 24:1 or 50:1? I know there was discussion of 57 vs 58 bearings

    Yes the water tube was seated into exhaust housing. I used compressed air to check that circuit at least was open. Everything appeared to be reasonably fitted during install. Thanks for reply.

    After installing new water pump, good water flow from exhaust port. After few minutes running, no way to hold hand on powerhead too hot. What is normal operating temperature of powerhead for this 1958 Seahorse 10? Could water circuit be partially clogged?
