I'm running a 1994 yamaha 15hp 2-stroke I just picked up a few weeks ago.
Initially the stream from the telltale was strong and cool at idle or when running 5mph in the marina, however once I opened up the throttle it would pee for a few minutes and eventually cut off completely. Then it would steam which I took as water evaporating in my hot engine. Immediately cut off motor and paddled back in
Since then I have replaced the impeller and changed the lower unit gear lube. While I had it open I blew both the pee hole and the LU openings with compressed air to try and clear any debris or gunk and I got nice air pressure through the system, so I put it all back together.
The motor runs great, but I am back to the same problem... I get a good stream at idle or slow, but after opening it up the stream stops completely. oh, and after I let the motor sit and cool off for a few minutes the stream comes back good as ever.
Any advice? Does it sound to you like there is something lodged in the cooling circuit somewhere? There are distinct symptoms: runs fine at idle, stops at open throttle/underway.
Thanks ahead for your help.
