The only doubt I have is that by this leak the engine doesn't rev up as water is not getting into the pistons, but again seems feasible that water getting into the plug cables can cause bad or non spark. Just trying to understand the issue.
Thanks for this pictures this clears my mind a little bit I guess it seems everything is casted together in iron or some material as that, this means this can withstand better over heating? The jacket cover still aluminum I guess.
That answers part of my doubts, so if it's leaking not necessarily water is in the Pistons.
I have doubts of the overall failure that doesn't rev up but as Jimmbo said maybe water leak is causing no spark. I don't see the cylinder head in the diagram, is there one? or how does this work?
I'm confused with this motor, not as my other force outboard, that water jacket is not the same as a cylinder head right? Are the plugs threaded there? Typically I've seen that the cylinder head gasket has the contour shape of the cylinder bores this jacket gaskets is nothing like that... It's...
