one riser and manifold is extremely hot

[tim10034]

I ran my boat with a water hose today and decided to touch the manifolds bc i have read so many reports about manifold going bad and one side was extremely hot....is this something i should be concern about ..the last time i ran the boat my temp gauge read cool that was about a month ago...thanks

Re: one riser and manifold is extremely hot

When you run on the muffs your engine is really starved for water. Having one manifold hotter than the other is no big deal. Put the boat in the water and do it again. You should see that it's fine.
