Those are the high performance version of that motor. A lot of people pulled the powerheads off of those and put them in the cars. Just because they were more powerful.
That is a false compression reading. Let it sit overnite and try it again and your idle could be lower. look to make sure the rollers are in good shape on the 50.
Retest your compression have never seen one of those that high. What is your idle speed? THat needs to be set in gear on a warm running motor. Not unusual to have a bit of a clunk when shifting.
It is a scott 3 cylinder lower unit, If it is the same impeller those are being made yet by people. Join the AOMCI and you will find somebody there to help you.

Or the AOMCI can help a lot with that. I believe those are Crosley car engines.
To anyone reading this post DON'T DO THIS!!! This set up is a huge safety issue. This is a potential fire hazard among other things. Use your common sense people, Not all info on the internet is worth following!!!!!
Pay attention to the #1 cylinder and check for spark before anything. That is an early OIS system and did not have the best quality optical eyes in them. And keep the starter turning until the needle stops on the gauge.
So take it to a mechanic and have the lower resealed and pass the receipt with the sale. Tell the buyer to pound sand because he is trying to screw you. He will spend $400 on the reseal and pocket the $3600 he saved. Do not sell people like that anything you will never be rid of him!!!
