1990's Mariner 30 Hp 2S (Yamaha based)
I thought some new gaskets had sorted a leak between the inlet manifold and the reed block / main block. Alas not - it gave out after about 10 miles and I ended up getting a tow in this afternoon (from about 200 m from the slipway).
Using 1200 grit wet-and-dry and a very flat surface (kitchen worktop!
) in different directions, the inlet manifold casting seems to be as flat as such a crude method can determined. In the absence of a surface table and with the block still on the engine is there any way I can determine if the block is warped? Mucking about with the edge of a steel rule didn't show anything.
I may not be able to read replies for a while - I am off to beat the outboard senseless with the branch of a tree, as Basil Fawlty did to his Maxi....
