Chris Craft XK 22 Chevy 350

Post by dave tuttle » Thu Jul 19, 2018 8:50 pm

Hello - Upon five (5) minutes after initial start up It looks like steam coming from starboard side exhaust. (Actually quite a bit of what appears to be steam is visible.) Engine temperature reads around 185 - 200 F. It appears ample water is flowing from both exhaust.
Any thoughts what could be the root cause of this dilemma? Otherwise this is a strong running engine with approximately 150 hours since a complete rebuild.
Thanks in advance for any help.
Dave Tuttle

You probably have old broken off impeller fingers or rust partially blocking the flow somewhere.

Which model engine do you have?
