This should be an easy gasket to find but i'm struggling... the motor is a 1970s Marine Power 454 (in a 1973 36' Tournament fisherman)
... yes amazon has it but it can't be deliverd until next friday...
its the gasket for the thermostat housing on the top of the engine
Marine Power part number 16.50 - 00096 (doesnt seem to help)
7.4L Thermostat to Engine Gasket GM 10105135 (maybe?)
I feel like this should be common enough to buy at an autozone or napa - i mean if it was on 454s?? I'm just looking for the wrong part number... can you all help me tranlate this part numbers into a common gasket number?

the marine power engine manual lists the part number as:
0303-009
GASKET: T-STAT ENGINE
V6/V8
AC Delco Part Number 10105135
I've ordered two gaskets and both are wrong... if someone can help me with this simple and common thermostat housing gasket for my 1973 Marine Power 454, i'd appreciate it.
now i'm concerned that engin manual pictured above is the wrong one...
@Lee Dahlen i ordered this one and it looks like it might fit https://www.amazon.com/dp/B08CD36T8W?ref=ppx_yo2ov_dt_b_fed_asin_title
This is one of my search prompts that delivers decent results and the orange one i have in my possession and it might work
thinking about ordering this one https://marinepartssource.com/catalog/product/view/id/200574/s/big-block-circulating-water-pump-gasket-crusader-rm0204?gad_source=1&gad_campaignid=14644923582&gbraid=0AAAAADtXKRTaXRWNC-s_HucTkg87Dvv07&gclid=Cj0KCQjwrPHABhCIARIsAFW2XBNsQ2iUGBFQ-7fhiXmfxUSeQ7mvGZIBgGDj7buj18vyUgfk6zCz3OEaApPzEALw_wcB

Sometimes i feel like i'm just talking to myself 🤪 is anyone else here with an old Marine Power 454? i've struck out 3 times now ordering thermostat housing gaskets its getting a little embarrassing... i just ordered two more from marinepartsource... hopefully the next one is the ticket... the frustrating part is that the correct gasket LOOKS just like these but larger so its very hard to 'eyeball' - there is something about this marine power closed cooling setup i have which is making it hard to find this... dumb question, but can i just cut a gasket out of material myself? I'm pretty crafty. anyone? hello?
You can make one yourself, but I just bought the standard Crusader gasket from the local marine store. The intake manifold should be the same on all the marine conversions. Mine are raw water cooled and from the early 80s.
Maybe your engine part is not OEM?
strike 4 & 5 ☹️
i ended up using the one i ordered off amazon, the first one a got, we will see how it works when everything is running but it seem to fit nicely: https://www.amazon.com/dp/B08CD36T8W?ref=ppx_yo2ov_dt_b_fed_asin_title
As Lee mentioned in another post, sometimes it is just easier to make your own gasket using sheet gasket material. I'm surprised the Chris-Craft 454 didn't use an early '70s standard Chevrolet 454 thermostat gasket. I never had to get into gaskets in the 5 years I had 1981 era C-C 454s.
