oil/gas ratio

[coburn]

I know this question has probably been asked before but i can't find the answer, I just purchased a boat with a '95 evinrude 50 hp outboard the original owner said he premixed the oil 100 to 1, I thought it should be 50 to 1 can you please help, he has run it like that for years but he may drive it differently than i will thanks for any assistance:

Did he tell you that before or after he sold it to you? I wonder why anyone would admit that sort of thing about an engine they were trying to sell. maybe it doesn't matter, but to me it would be like a guy trying to sell a car admitting he had a ridiculously long oil change interval. Usually we try to convince buyers we take good care of the stuff we're trying to sell, no?

Are we right to assume the vro has been disconnected cause if it isn't with a 100/1 mix and the vro he was probably running a rich oil mix. it would be a good idea to check your compression right now so you know where your start point is. Best of luck. Rick.
