Your motor is a 1947, made by Gale Products Division of OMC. Those motors had rather poor seals when new, and were designed to use "Outboard Motor Gear Grease", no longer made. Most people use Lubriplate 105 "Motor Assembly Grease", available from NAPA Auto Parts Stores.

Because of the poor seals, frequent re-lubrication was needed to get the water out. People accepted that back in 1947 as normal.

Put up a pic of your motor because a 1956 will NOT take lubriplate grease as it's a scott built motor with gearshift takes 80w90. A 1947 will take lubriplate.

Ok fellas I'm back.. well so I have recently been told it's a 1956. Finally got it starting and running then found out it had a bad impeller. I replaced it to day. Well now it won't start nor even attempt to start. Here is my questions lol.. 1. Is the propeller supposed to turn free while starting? 2. I can't seem to find a neutral point to get it to pull freely. What could I have done wrong??

My apologies, it is a 1956. I was confused by the similarity with the 1947 Gale model. Your model does indeed come up as a 1956, made by Scott-Atwater.

Yes, the propeller should turn freely if the shifter is in neutral. I'm not sure if there is a starter lockout on that motor or not. I better not say, because I might be wrong---again.

Well the only thing that changed was a new impeller unless there is some wrong way to put it back in. It is a different impeller from the original 8 prong it's a 10 and was about a 32 longer. Could it be that it's to tight?

Did you fill the lower unit with lubriplate or 80w90. I don't believe you have a starter lockout, your impeller will be fine unless you put the omc propeller in. Did you connect everything back up correctly.
