YEs that is one advantage of using the later model rods. I stuck all 6 pistons in the block in less than15 minutes.. easy cheesy...

I use aviation form a gasket on the block halves and the cork spaghetti seal . Never had one leak....


Would that be the stays pliable or the hard setting type :?: I assume you do a very thin layer to not upset the crank line bore tolerance machined without any sealant :?:

Cork seal - is that just a very thin piece you place on the block surface and it squishes to very thin  :?: Where do you get them  :?:

no it is a semi pliable and goes on very thin so squeezing it out of the bond line is easy to achieve. the spaghetti seal is a factory part. the crankcase half of the block has a groove machined in it for this  seal.

Nice tool.

The hidden advantage of the 'put the pistons in first' technique is that one can test the 'feel' of the assembly by moving the piston up and down.  If I feel something I don't like, I yank the thing out and see if a ring is broken, the gap is too tight, or whatever.

well right after you write me a check you can take it for a spin. this boat was built in AUSTRIA by Dieter Schulze, shipped tot he USA to compete in the World outboard Championships in 1971. after that it was run by  Stew Diebert in Region 10 until 1975. History is traced and Stew has actually stopped by to see the boat during restoration  and told me the story on it arriving here.  COMPETE deck and bottom off restoration competed last year. Ready to hit the vintage and historic APBA circuit this year.

Kidding about the test run. That is quite a boat and motor project.
What top speed could your setup reach in perfect conditions?

Power head is complete except for an internal wiring harness and new timing pulleys and a belt. Time for a break to  address other issues, then start on the mid and lower...thanks for  the interest.

Lower disassembled. New seals and O rings all the way around, new pump gaskets, check and set backlash. all seal surfaces in perfect condition. Someone knew what they were doing with this one before me..  Looks like the driveshaft seal area had been plasma welded and turned down, same with prop shaft.. Still had clean oil in it at disassembly....

fit checks are done. Interesting the combination of  engine studs tuner bolts and engine bolt hardware required to install this power head. BUT it is finally on the mid for keeps....
