I just spent two days on the lake and experienced some trouble with my motor, so I'm hoping that some of you guys might be able to help me figure out what I need to look for. The motor is a 1973 Evinrude 25hp with tiller. It runs really great most of the time, but every so often it just seems to suddenly rev up the rpm real high and the prop quits turning. Over a period of two days on the lake, it happened to me about 5 times. It only seems to happen when I am cruising at wot. I'll just be going along just fine and then it will suddenly happen. I can let off the throttle and then it will catch and start turning again. It will run perfectly for a while and then it will happen again! Its as if it just momentarily jumps out of gear and then when I let off the throttle, it goes back into gear. It only happened about 5 times over a period of two full days on the lake, but I'm pretty concerned about what it is and want to find the cause and fix it before I take the boat out again.
If any of you guys have some suggestions for something that might be causing this or anything that I might try to correct it, I would really appreciate the assistance. This has never happened to me with this motor in the past, but I was carrying more weight this time than what I have ever carried before. It is a 14 foot semi-v starcraft and I had a guy up front and then about 20 gallons of water in a bait tank toward the rear/center of the boat, and also a bunch of fishing gear.. I thought that maybe the extra weight might have something to do with it, but I have no idea what it is.
