Force Cooling problems

[forceNightmare]

I recently bought a 1990 Bayliner with a 50hp Force and have had nothing but problems so far. I got the boat at a really cheap price but dont know too much about fixing them. So far I had an ignition problem and had to replace the CDI box and the coils as well as disconnect the emergency shut off switch. Now, I was able to get the boat running but am not getting any water at all from the exhaust ports. I have been using the square muffs and have yet to put it in a tank. My question is even though I have yet to actually test the motor in a tank chances are I have already burnt the water pump up anyways right? And also I forgot to mention that this boat has sat for six years with out starting so it is a miracle it even turned over. Aslo I know there is some kinda of gear lube I am suppose to put in the lower unit but where. Please excuse my lack of knowledge but I am hard headed and do not want to pay a Marine Mechanic ninty dollars and hour to get my boat back sometime this winter. Please advise on what I should be looking for with this motor???? It ran for about five minutes before the overheat alarm came on and I shut it off at that point

Re: Force Cooling problems

Untill you get a manual.Look up a parts diagram boats.net has good diagrams.
Any parts you need can probably be bought on this site.
If it sat for 6yr the impeller should be replaced.
The gear lube is drained and filled from the very bottom of the drive.There is a screw on the side(see pic) DON"T touch.It connects the shift linkage and will require dismanteling to replace.
The square muffs might not be right for that motor.It requires a special muff(see pic).

Re: Force Cooling problems

Muffs dont work with many motors ..or not well enough to get a good flow ..I f your motor does not have a proper tell tail ( pisser ) then fit one as its the only sure way to know its cooling ..
