Hi, my name is Kerry
Your exhaust rubbers may have burned through from the inside from not enough water getting sprayed into the exhaust.
That could be bad a sea water pump or a resriction in the cooling system.
If the pump is good, the most likely place for it to start plugging up is in the risers.
You need to replace the exhaust boots anyway, you can check and clean the risers while it's apart.
The leak in the exhaust rubbers won't cause an overheat, it's actually the other way around, the overheat causes the leak in the rubbers.
Not sure what that means... Going to replace rubbers,,, but then what.. ran great last season... first time out this year... running on Lake Erie
When was the last time you replaced the water pump impeller?
never.. never head of that.. big job?
How long have you had the boat?
Usually do the water pump every few years.
bought it used two years ago
You remove the drive, drain the oil, separate the lower from the upper. rebuild the pump and put it all back together.
water pump on the front... like a car...???
Two years plus whatever length of time before he sold it, it's probably due for a water pump.
In the drive leg
wow... ok sounds like more than I can do...
I do it in about 1 1/2, an outdrive water pump and oil change.
$100 + plus labor
can I kiddnap you ..lol
Ok.. thank-you for your time
These drive should be serviced regularly. You take it off the boat, check the water pump, change the oil, check and grease the u-joints, change thw zincs and put it together
