"We have what we think is a 20

"We have what we think is a 20 hp sea king. model number is 76X10370? We got it running great this past weekend, but would like to put a fresh impeller in it and change the gear lube. what weight gear lube is recommended and where could we find an impeller kit? also what mixer is recommended? we were running 50:1 and it seemed to be smoking and running just fine. Thanks in advance."
 
Any chance that you could find a model number such as [SIZE=-1]VWB27920? That would make it a 1967 20HP made by Chrysler. Most motors of that era run an 80/90W gear oil in the L/U. The fuel mix you are using should be fine. Even better if you can find synthetic oil. [/SIZE]
