I have a 1988 Force 35 HP outboard motor that is overheating.

Customer Question

I have a 1988 Force 35 HP outboard motor that is overheating. It is pumping water. A mechanic says to check the themostat which I cannot locate.A man at the docks said that he had a motor that was overheating due to one of the ignition coils not firing. This really didn't make sense to me.The pistons and cylinders look ok but the head gaset has a hole blown in it which I am going to replace. The only thing I can think of is ther is cloggage above the output ports Don't know .please assist.

Hi, ok I see this allot.

 

The problem is the water pump drop the gear case and check it. They need to be replaced every two to three years as not to get into overheat trouble. You may take it out and think it looks ok but replace it!.

 

You see the impeller provides water with pressure to the power head for cooling. The water /pressure needs to be suficiante enough to fill the whole cooling system cavity of the block in order to pull the heat away and operate the thermostat.

 

On most overheat I will replace the thermostat anyway for insurance.

 

 

Hope this helps you out,

 

Thanks

where is the thermostat?
Expert:  Whitecap36 replied 5 years ago.

There is a thermostat cover on the top/back of the head. on some models they didn't use the thermostats on the 35. If the cover slide into the head with deep sides on it (insead of just a flat cover) it will not use one.

There is no cover on the back of the head for a themostat. It is just one solid piece. I dont't understand. "If the cover slide into the head with deep sides on it( instead of just a flat cover) it will not use one". please clarify. it seems tou are missing some letters in you're text which makes answers difficult to understand.

If the cover slides into the head and has deep sides built into the cover that slide into the head then it doesn't need a therm. Is how it should have read, sorry. I

Now if your head has a one piece water jacket cover along the whole head with lots of bolts holding it on and has a bump on top where a thermostat would be underneath it's there. You'd be able to see a part of the therm looking throw a hole on the inside of the head possibly.
