Does anyone know the interchange numbers for these Lark III Bearings?

[mr-asa]

The lower unit for my 40HP is bone dry and fairly rusty inside. I’m looking for new bearings but I am 100% against paying retail outboard prices for them.

After doing some searching, I’ve found one of the bearings, but not the rest
#17, 375761 Roller Bearing is a Timken 12580
$72 on Marine Engine (and similar price elsewhere) https://www.marineengine.com/newparts/part_search.php?part_num=375761
A more realistic price of $16 for the bearing can be found on Amazon. https://www.amazon.com/Timken-12580-Bearing/dp/B000BZAAW2

Does anyone have the rest of the bearing part numbers?

Give ’em a good wire brushing. The numbers should be stamped on them.

307545 is a SKF 6304 NDH3304 or sierra 18-6037

The only one that had any number was 307545, and the actual number was worn off. It had “Norma” and “ade in US” on it.

The remaining 3 (I think) are too small to have numbers on them

Awesome. One more down. Thanks

So, I’m definitely in need of 376858. I’ve been able to find the rest.

Does anyone have one?
Also, does anyone know the water pump and seal kit numbers for this?

Water pump kit is 379775 for the entire kit including new housing or 379768 for the impeller kit only.

Seal kit is Sierra 18-2686 or GLM 87607
