1977 Evinrude 140 hot starboard side.

[rochelle howell]

1977 140 hp. Evinrude.
Overheat on starboard side. Idling.
New water pump w/ housing, stats, poppets,
Still hot up to 180° idling
Pulled water jacket covers saw this
Cleaned out thoroughly, new gasket, reassemble.....still hot. 180 idling.
Pulled head.
Thought I would see a LOT more crap in there.
Doesn't look bad.
Diverters in their respective places, but not round.
Appears as if they're not allowing water flow around cyls. anymore.
Don't see any crud in between cylinders.
Pistons look good, cylinder walls good, no scoring or gouging.
No wear ridge whatsoever.
Still has good crosshatch.
Motor runs real nice, starts very quickly, idles smooth.

Looks like I need diverters and new head gaskets.
What size fuel line for diverters?
Any doo - doo to hold 'em in place?
Thoughts?
Thanks in advance!
