Brand new Yamaha F225. runs great. I tried to winterize and had the engine running with the hose adapter and there's no water comming out of the cooling pilot hole. I was afraid to run it too long so after a couple of minutes I shut the engine. All this time never did any water come out of the pilot hole. I had a mercruiser alpha I/O and a Mercury outboard run it with the same adapter never had this problem...am I doing something wrong? engine has 5 hours on it

"Dinu,

It was no joke. Or you can blow it out with a air pressure hose. Or check your water pump and T-stats. Those r the unual problems. Also make sure you have enough water pressure in your hose with your flush attachment.

Good luck..

P.s. I use that hose trick today when I was flushing my motor. works every time, the only problem is I get a mouth of salt water.."

You will find on a lot of larger Yamaha four strokes that when up attach the muffs to the gearbox water pickup that they will not get enough water to fill the power head therfore the telltail will not work. If you have 2 hoses hookup one to the flusher fitting and one up to the earmuffs and it will be ok. Other than that run the engine in a container of water.
