For those who care and if this interest you. here are some pics of what we did to Ditchdocs Merc. Cleaned up the intake passages, took 7CC's of the heads and machined the intake to easily accept the boyeseen reeds and a few other things. Got it all back together and running and found the lower adapter gasket was leaking and water was coming out of the engine mount. Had been for a while due to the whitness marks (rusty substance) Had to take all the way down to the trim assembly. Replaced the gaskets and broken motor mounts plus I actually got a picture of Doc working!!!!LOL!!!</p>
Pictures </p>
1) #1 piston coked up. Cause of high leakage</p>
2) #1 piston after bead blast</p>
3) block torn down</p>
4) block after cleaning</p>
5) Heads machining 7cc's off</p>
6) Mercury blocks get alot of wear from the sealing ring rotating. The sharp edges accelerate this wear. Simple solutiion to slow it down is to just knock off the sharp edge</p>
7) Intake after maching screw slots</p>
8) This is the all the parts layed out for assembly</p>
9) Block assembled</p>
10) Having to replace the adapter gasket</p>
11) DOC WORKING!! DO YOU BELIEVE THIS??????????</p>
12) The boyesen reeds</p>
