Circulating pump
Ok I just got home with my new/used 2000 28.8 Sunsation with 70 hours. when i was tuning it up for summer use, I hooked up the hose, and when i turned it off from running the engine, the lower pump hole was leaking out fresh water. I was told i can just RTV the hole up? I am going to install a new raw water pump and circulating pump now. But I would like to know can you really just plug up the seep holes?
Thanks!
Thanks!

CAPO71,
Secretformula has it right... Presently the seal on the pump is gone, thus the water, and the next thing will be the bearing...
Looks like it's time for a bypass kit and eliminate the problem
from ever happening again, not to mention the cost of pumps
on an ongoine basis... Stainless Marine does a really nice job
and I have used their products on the past three boats with no problems...

CAPO71,
Exactly, the raw H2O pump does a fine job, and in many cases better than needed, unless you have a closed cooling system...
Just an fyi, here is the URL for Stainless Marine... They are very good and if you have questions they are also quite knowledgable... www.stainlessmarine.com

PS... If you do have a closed cooling system then you will need to keep the circulating pump...

It seems that many of the mercury circulating pumps fail very early. I have twin 385 mpi's with 50 fresh water hours on them and both of my pumps leak. I have talked to a number of other mercury owners with the same problem.
Does Mercury have a class problem? If not, why failures at this low number of hours.
How many members are experiencing these failures?
