Was the V8 mid section re-used for the SST100 engine program? I think when OMCs V8 race engine reached its peak in 1985 it was not long after that when Merc came up with their "new" hydraulic up/down mid section. I never understood Merc's "studs down" decision either? Those V8 steering arms were not cheap to make either..... with 2 pressed bends in each.Quote:

Same with the Johnson Stinger GP

Being an F1, even doesn't mean absolutely even order ?
Notice the fishing crank (believe it's a fishing crank and compliments the fishing exhaust layout), the V4s are significantly uneven in comparison, hope you can see that in the image in comparison to piston position of the early F1 image.
In the mid , was the bottom V4 exhaust even with the top? I know you said one outlet.
Back in 1983 there was a problem with the connecting rods screws. I remember OMC made extra strong screws and installed in my powerhead.Quote:

This is the rods from the block above..but cant tell if that is the older or newer rods.

A mix of pictures from the engine/block above. I did have a picture of the crank but cant find it now.
