cooling problem 7.5 mercury

[skint back]

I bought a 7.5 mercury that had been in storage for 3 years. when I ran the motor there was no water coming out of the pee hole. does the motor need flushing or is it a more serious problem. p.s I ran the motor for 3-5 minutes before catching it. could it have messed the motor up.

Well if it's been in storage for 3 years and I just bought it I'd be doing a full service on it.It could be anything from a pluged indicator hole to the impeller being burned out.How hot did it get?smell of burning paint? could you touch the p/h ?or did your fingers stick to it?Did it stop running because of the heat ? It might be fine. Pull the gearcase and check the w/p.One more thing if you don't have a manual get one, you can order on-line from I-BOATS or get one locally.

You need to replace the impeller in the waterpump every two years, no matter if it has been used or just sitting in storage.. <br /><br />Running for a few minutes with no cooling, it's hard to say if ya messed it up, but it's probably ok...

Re: cooling problem 7.5 mercury

Hey Skint, what ever came of this? I am having the same issues with my 7.5 merc. I had problems with the gears, which I fixed, but now I can't get water through the motor and it got hot!<br /><br />The impeller was replaced on mine, and is still in good shape, but nothing is coming through. Any ideas?<br /><br />Treever
