The impeller housing is in a less-than-ideal location in my boat (a 2007 supra 22v with 340 cat engine) -- directly below the cat system, with no visibility of the impeller itself. I imagine there a few other owners of cat-equipped boats on here that have faced this challenge...
I removed all bulkheads and panels for access, and was able to remove the housing cover, exposing the impeller. But given the awkward angle and lack of visibility due to the catalytic converter being in the way, I cannot seem to get enough leverage to get the impeller out of the housing.
Thanks to a suggestion via the search function here, I tried spraying silicone lube into the housing and cranking (not starting) the engine, and puling it out with needlenose pliers... but no luck. My arms and hands are destroyed, and the impeller is still in there (though a bit torn up now). Anybody have any advice? Are there any tools that might be helpful?
Thanks in advance.
