After impeller & water pump went out out my 97 OMC/Sunbird/Coral/Volvo/Penta I/O 4.3GL Vortec (Yes, all these names are on my boat) I went thru the usual complete "head job".<br />This lasted 2 days . . .cylinders filled up w/water again!!!<br />I'm thinking manifolds & risers but can't find any to match my specs.<br />Am I missing something??<br />Can anyone recomend a site where I can enter my application (yr/make/model/etc.) and actually have my parts come up on the screen w/price & availability? <br />
