overheat and water flow

[trackeravalanchedc]

Trying to figure out where this hose is suppose to hook, it looks like it has a small ball valve in the end of it. Ive been getting a steady buzz alarm and I seem to be in slow mode, the motor will not go over 2500-3000 rpms. It idles good and revs good when not in gear. I put it in gear and SLOW im getting very frustrated. here is what i have done so far; unhooked wires until alarm quit buzzing and it is a tan wire that comes from the oil tank and hooks into the wiring harness. here are some pics of the hose.......Could this hose be my problem? HELP the motor is a 1990 200hp johnson vj200slese
:facepalm:

Re: overheat and water flow

When's the last time the water pump was changed ? Did you check the temp on top of the block ? Is it defineatly overheating ? The item your showing in the pics is to syphon any water out of the lower mtr cover if you get water in it.

Re: overheat and water flow

i really dont think the motor is overheating because the alarm starts as soon as the key is turned to on. the wire i disconnected i followed it from the oil tank that made the buzzer quit. glad to know that is just a syphon hose i was completely confused on that...i couldnt see anywhere it went and had never noticed it before! so bad thermostats ya think?

Thermostats wouldn't make the alarm sound the instant you start the engine. Something doesn't quite add up though - the low oil alarm is an intermittent beep, not solid as you describe. The other thing to check would be the vacuum switch, which is supposed to trip when there's a fuel line obstruction upstream from the fuel pump.

You can easily check the thermostats by letting the engine warm up at idle, the heads should be in the range of 145 deg F or thereabouts. If you put your bare hand on the heads you should be able to hold it there for 4 or 5 seconds - it's quite hot to the touch but doesn't burn you.
