weak stream from tell tale hole

General Boats and Motors

I thought I had a water pump problem but after replacing it saturday there is no difference. It starts out about half the force it had last year and the longer it runs the slower it becomes until it is just dribbling out.No overheat alarm and I checked the temp of the heads by touch and they dont seem to hot,I can hold my hand on them. The motor is a Yamaha 80 hp 3 cyl 2 stroke. I have taken a small wire and made sure the the pee hole isnt clogged,any suggestions would be appreciated
Thanks

I had a similar problem this year…turned out that the discharge line was clogged. I ran some weedeater line in and out of the pee hole and through the discharge line and it cleared out the clog.

start by using an air compressor and blowing air into the hole
