Question
OMC Stern drive - The water pump was clogged and I need the entire repair kit

I have just bought a 1985 17" Renken bowrider with an OMC 2.5 liters Engine and stern drive. The water pump was clogged and I need the entire repair kit. The only numbers I was able to get from the drive are: Mod # 983486 Serial #J400028. Can you please advice what pump repair kit I should get?

Submitted by: Rico

Here is the water pump kit.


Question
My omc 400 sterndrive is overheating!

My omc 400 sterndrive coupled with a 4cyl chevy engine overheats and I cannot locate the thermostat. Everything else seems to be ok. Help!

Answer

The thermostat is located on the front of the engine on the top of the head. Have you changed the impeller in the drive or checked the exhaust manifold to see if it is plugged?
