239 mercury rear main seal retainer

[Doug Black]

I have a 41 mercury flathead and need the upper rear main seal retainer. Van Pelt has one for 8BA. Will that upper part fit my mercury? If not where get one?

Ask VanPelt...

Firstly, you need to ascertain which style crankshaft is fitted in the engine; one with double slinger or full seal?

When we took the engine apart, it had the rope seal. I took the top piece to Hershey to buy a new one, and someone stole it off my dolly. Thanks for the info.
