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?

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

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

How old is this motor?

Ten four. Right before it happened I got stuck on a mud flat so I just figured it somehow sucked some sort of junk up in there. To the boat shop it goes. Hope there not busy cause this weekend looks like a good weekend to put some slime in the boat

The water runs out the pee (inspection) hole BEFORE it goes into the engine. If the engine got hot, which is why the buzzer went off, the impeller is gone. If the inspection hole was stopped up, the engine would have stayed cool from the water pump still working, and not set off the buzzer.

I've seen lots of engines that were peeing, but still getting hot. That's because the thermostat was bad, or the water jacket had stopped up, or the impeller was worn to the point that it would pee, but not send enough water volume to the engine to keep it cool.

not old. I would say 07-08

Good idea....it was getting hot for the alarm to come on. Probably stopped up with mud and silt.....Impellor probably damaged also.

Its time for a new impellor then

BTW, it's best to change the thermostat if you don't know how long it's been since it was changed. I like to change the thermostats every 2nd impeller change. Should be serviced every other year or so on an impeller. When they go bad, it's usually to late, especially if you're miles away from your trailer.

5-6 year old engine. The impeller probably dry rotted and came apart. Make sure to check the thermostat housing if the fins are missing from the impeller. They can stop up the thermostat and not let the engine dump the hot water out causing an over heating issue.

Make sure you remove ALL the fins if the impeller came apart.

In all fairness to your repair shop, most people don't service their engines properly like you didn't. One problem usually causes another. We find secondary problems all the time. It's your shops duty to inform you about those other issues before they get worse.

I can't imagine that a reputable shop couldn't ever fix your problems like you stated. How do they stay in business if they're incompetent? ;-)

Just so you know a walmart bag will block it on the bottom unit and make it run hot . So keep your trash in the boat till you get back .

Don't know what part of MS your in but Mike Tabor at Southern Marine in Olive Branch would treat you fair and does good work.

Take the cowling off and the line that goes to the peehole, try flushing it out first. I've had mine get clogged up with some grass out in the middle of lake Washington and just had to take the line off and flush it out. Ran fine after that. Then again, it you haven't changed out the impeller yet and it's a 07-08, it's time anyhow

You are probably right about them finding other issues that I can not see but they would fix them and then tell me after it was too late. I learned after a few times and would tell them up front not to replace anything without calling me first. Then it seemed like there was some sort of friction there and the service I got was not good. A boat repair would keep me off the water for a week because it seemed like my boat got put in the back of the line. Thanks for all the replys. I got a impellor part this morning and its going to be fixed today.

If a week on a repair is the back of the line...I need the number of that shop! A week is not a long time for a boat shop especially spring/summer. Month waits are not uncommon for a lot of shops.
