Aqua raises a good point, one that has always confused me….What the heck was that gasket designed that way….Why didn’t they design the outer diameter of the gasket a little larger so it conformed better to the gear housing and upper bushing/brg assy. Those little cut outs for the water pump screws are ridiculous…And, the gasket would seal much better if its outer diameter was bigger and conformed properly to the bushing and housing…
I forgot about the different recoil mount positions of the two versions of powerheads….So, it seems very unlikely that the powerhead is a mismatch…The base gasket is still suspect though…
