background……the kit I purchased was Amazon stuff from China
I did a pressure test on my CD gc and found it leaking(Bubbles) on the prop shaft seal
Replaced the prop seals and falsely assume others were ok and closed up the GC …..mistake !
Found the Shift rod seal was leaking (bubbles) so I decided to reopen the gc and change shaft and shift seals … that went well
Wanted to check the underside of the impeller housing so I lifted the botton plate to access the clutch & replace the last seal under it . In so doing I tore it up in a pile of oily mush
then….
- mistakenly assumed I could replicate the orange gasket to seal up the clutch area under the plate and then reinstall all the original impeller housing saving my orange gasket for a rainy day. That cd will be sold so I kept it in my new kit …for now.
- made some copies and upon reassembly, I felt someting was wrong because my new gasket did not fit and was blocking the upcoming water passage and that little curvy section would not seal things up & would allow water to access the lower GC oil section
- in conclusion.. .all I had to do was use my orange new kit gasket to simply shape a new 303399 .
- Some will say ” buy a 303399 🙂 ” but I hate ordering $5 U$ parts with $20U$ shipping plus CDN exchange and taxes….
- live and learn .. always 🙂

March 5, 2023 at 12:08 pm #273450thanks for info …I managed to cut some with success since the older base gasket pattern is not curvy like the newer impeller base plate gasket.
I have the pattern and can now cut new ones for years to come !!! . I do not usually mess with the GC sealing or the impeller base if I don’t have to . Garage is filled with 3×4 HPs, couple of Cds Merc 3.9 etc… so my gasket making days are slowing down fast 🙂
thanks nonethless for the heads up
