I've recently purchased a used boat with an Evinrude 70 HP outboard engine. The only number that I find on the motor (other than emission info) is ACN 008 414 917. Is this the serial #, and what does

Your best bet is ebay for a replacement user manual. Take a look around, you will come across one... For the meantime, gas oil ratio should be 50 parts gas to 1 part oil, i.e. 50:1. General care: Dont go full throttle for any length of time. Cruise of 3/4 throttle... Always flush engine after use in saltwater, including washing down exterior. Keep spark plugs in good order and check prop for fishing line wrapped around in near the prop hub. Otherwise, get a yearly service and have them check the water pump and replace as needed, get it tuned etc and gearbox oil changed.

I have found that 99 percent of the time when this happens it is carb related. It is very possible that you picked a a small piece of grit or trash in the high speed jet of one, or both, of your carbs. I would be willing to bet that pulling the carbs and cleaning them will resolve your problem. I am almost positive that will fix your problem, mainly because it sounds like you've already tried everything else. I had this same problem last season, and what had happened was I left the vent open on my fuel tank, we got a shower, and I pulled just a small bit of water into the carb and that was it, she would not do anything over idle until I pulled the carbs and cleaned them. i even put the water muffs on it and let it run in the yard for about an hour thinking that it would burn the water out, but i was wrong. Anyway, clean the carbs and i think you'll be in good shape, Good Luck.

Hi, did you buy your engine used? Sounds like your gonna have to get the carb or carbs cleaned. Its possible you could have a stopped up fuel filter, or not enough spark but i am guessing its gonna be the carbs. They got some gunk in em i bet. Probably old fuel turned to gunk from setting up. I had the same problem on my 40 horse.

Testimonial: "Hi, thank you very much for your help, I will strip the carb down and have a look. Once again, many thanks, I am very greatful"
