[monsoonpaddle]

hi guys , i tried to previosley add a question but i think i stuffed up and it did not appear. ok, i have a 225 , 2004 model that was shipped from canada to philippines and was not commisioned till 2008. this engine has only 50 hours but i have a problem with overheat spike. the engine has been run at speed for 10 hours at a time and with no problems but when run for 20 minutes at speed the overheat alarm comes on.when going back to idle any ideas please.

Probably needs a new water pump.

Hi , thank you for the reply. Would you know how complicated this job would be and does it need special tools ?

No special tools required, it's not hard to do, may want to get yourself a service manual to show you how.
