Hello all, I have a houseboat with dual 1997 Mariners, 50 ELPTS 4 stroke 4 cyl. Starboard engine serial number 0G472932 -
Starboard engine starts fine and runs and pisses fine for first 10 minutes, then alarm sounds and steam starts coming from engine - very hot! I am thinking water cooling system is okay, because pissing stream is good.
I am looking for advice on where to trouble shoot. Motors are on a houseboat, and I am going to the lake tonight. Would like to have some ideas to work on, to see if we can't get this thing running properly again.
A. Could it be poppit valve? I read on another board about poppets going bad, but I'm not sure what those are or where to find them.
B. Could it be bad thermostat?
C. Could it be an oil flow problem?
D. Anything else I should check?
Thanx in advance for any and all help/ideas!
Kurt, in Tucson Arizona.
Replaced impellers both motors November 2007
Changed motor oil and lower unit oil both motors November 2007
Replaced oil filters, fuel filters and spark plugs November 2007
(Motors have 5 hours on them since this service - I start and run them 10 minutes every month or so)
Anything you can tell me about this motor would be appreciated!!
Thanx
