4.3 circulating pump weaping.

[paczowski123]

Well I've noticed my circulating pump on my 98. 4.3 mercruiser is beginning to weap from the port on the front. I'd assume this is not normal operation, and if it's like the usual gm automotive motors a common problem. My question Is I am finally ready to replace it, but my main question is where can i find parts? I've been searching for a good parts place To find parts and was wondering what yall had for suggestions. I've searched a little on the net but can't find what seems to be a good solid parts source with good descriptions etc? What do y'all think?

Re: 4.3 circulating pump weaping.

Thanks for the response, but how would I decipher which pump I need? Just by whether my timing cover is metal or composite? Or are the numbers kites next to the parts in coordination with engine serial numbers etc?

It seems as though the Sierra pump for the v6 and v8 is what I'd need? The one for $93?
