1965 60hp feels like the motor kills at high speed

[paulshaffer]

When running at high speed the motor feels like it kills and then comes back. At first it seemed to be only at high speed, but when running at a lower speed (with the trolling motor still in the water) it jerks the same way.<br />Also it has started jumping out of gear. I'll be going along and all of a sudden the rpms go up and I look down and the shift lever has moved out of gear. <br />What can I do to fix these problems?<br />Thanks.

Paps<br />I also have a 1965 60hp. I had been using a synthetic lower unit gear oil and it worked fine. This year in a rush to get in the water for the first time,I bought an off brand lower unit oil and first time out I had all kinds of problems with jumping out of gear. I changed back to synthetic oil and cured the problem. If this does not help it sounds like dog gears in the lower unit are bad.

Fishingtime,<br />Thanks for your reply.<br />I will try synthetic oil in the lower unit. Would this also be what makes the motor feel like it is killing when running?

I drained the oil and found that about a cup of water came out first. Where is the leak anyone know?<br />Thanks
