I am having problems with pumping enough water to my engine and have taken the plastic unit off the outdrive, its the one bolted up at the top of the feed tube when you drop the gear box down to check the impella (pre alpha mercruiser, 3.0 mercruiser engine, circa 1974) One of the retaining bolts has no threaded part for the bolt to go into and water was spraying out when checked with the hose. It has been put back like this last time by the looks of things. My question is has anyone had any luck getting round this problem by using liquid metal or a similar product? I was thinking of mixing some up and applying it like you would gasket sealer and putting it back, then perhaps making a steel plate to bolt to the remaining three bolts in the hope of stiffining it all up.
The other thing is that the plastic has melted quite badly, is this common? It must be the heat of the exhaust that does it, I have a spare that came off my origonal drive, but even that has been subjected to some heat at sometime?
