I have a 78 evinrude 25 hp short shaft motor, on the river Friday going to look for a new place to duck hunt. I was following the channel because I did not want to hit any thing flowing in the river. All at once the motor increased RPM and when I pulled the lower unit out of the water, the prop was not turning at all. After getting home and pulling the lower unit, I found the drive shaft was broken just above the splines on the yoke end that fits in to the forward/reverse gear. I visited the local repair shop and got a different shaft and the machanic put the entire lower unit back together.
Got the lower unit put back on Saturday and ran the engine is a trach can to make sure all was well. It ran and shifted ok....that leads us to Sunday.
Back to the river to hunt got about 3 miles up river and again then the same thing happened again. Got home and the drive shaft is broken.
Any ideas what could cause this type of problem?
Thanks for ideas and suggestions,
