I disassembled my 1978 150849S 150 HP which has a 1984 powerhead on it.
I cleaned and inspected all the parts, the link to the .pdf shows my findings.

I'd like a mechanic's opinion on the cylinder bores, on whether or not the gouges can be cleaned up, knowing the measured sizes of the #1 & #4 bores. I am guessing at the depth of the gouges, as I have no way to measure them accurately.
I figure I can try honing with a precision hone similar to this one: http://www.amazon.com/Lisle-16000-Small-Cylinder-Hone/dp/B000P1802O But for 3.5 in bore of course.
I figure I can try to hone, if the gouge is not removed by the time I get to 3.5030 on the bores, I'll just have the block bored .030 over. That would be a shame, as 4 of the 6 cylinders are good, and 5 of the 6 pistons are good.
As far as the crankshaft, I guess it's either find a good used one on eBay, or send mine out for spray welding & grinding.
