Trying to troubleshoot Evinrude Big Twin Issue HELP!!!!!

5 posts in this topic

My motor doesn't want to go anywhere when you get on it in forward or reverse and about a month ago test ran it on the river and never missed a beat, but the thing will move at trolling speeds all day long I'm completely flustered as to what this could be and earlier today between lakes I took the lower unit apart to see what could be the problem and din't see anthing wrong with that does anyone out there have a clue,or an educated guess as to what could be going on?

If it goes in gear and the prop spins, and as you say it will move at idle but not when throttle is increased, I would say you have spun the hub on the prop. The center hub has a rubber insert to absorb shocks, but when they let go, they require proffessional repair or replacement.

I also think its a spun prop,I bought a motor last year with a spun prop,I just bought a new prop,To have the spun one repaired was almost as much as new,Now I have 2 props but have'nt had the one repaired,Thinkin if I would need another its easier,quicker and only a few bucks more for new.

A spun prop would definitely be the first place to look to discover the source of your problem. But don't stop there! I once had a 25 HP Johnson that would act exactly the same way that your motor does. After trying many different search's, I finally discovered that the throttle linkage had come loose. Previously, my motor would start and run flawlessly, but would not go above a certain speed, in either forward or reverse. After re-connecting the linkage, I was good to go! I hope this helps. If you continue to have problem's, try emailing Surface Tension in the Duluth,BWCA Forum. He's my go-to outboard guru! Good luck!
