The Office Sweet 0 Report post Posted May 19, 2015 I recently purchased a 2008 250CR with a 5.7 Volvo. I like to keep some spare parts around, impeller being one of them. The boat info states that the impeller is a part #3842786, which from everything I can find has been replaced by part #21213664, my local marina states it's part #21951348. Can anyone tell me which is the correct replacement #21213664 or #21951348? I don't want to be months in and find I have the wrong part and can't return it. Thanks for any help.
