Thread: Motor problem

I have a 4 stroke mercury 25 hp motor. I run it weekly. A few weekends ago I noticed it quit peeing and the alarm turned on. I let it cool down then trailered it. Put it in the garage this past weekend and checked the hose that runs out of the motor and it was not stopped up. I could blow air through it. I am not a motor guy and do not know what else to do. I really do not want to take it in the boat shop because they charge me a couple hundred bucks every time and don't ever fix what I am having problems with. They are pros at finding other things to work on. Could someone give me a few tips on what to do. I don't know what any of the motor parts are called so you might to explain parts in shapes and colors, ha. Thanks.

waterpump easy fix

Probably needs to have the impellor in the water pump replaced.....You have to remove the foot to get to it. It is not a real difficult job if you are mechanically inclined. If you take it to the shop you are probably looking at about 40 bucks for parts and a hour labor at whatever their labor rate is.

Is it not possible that some junk is blocking the water flow somewhere?

Have you been running it in sand and mud? If not nothing should be stopped up.

you siad you could blow threw it so i doubt it drop the lower unit and look at the water pump
