North Australian FISH FINDER TM forums

Gday fellas today i plowd into a muddy reefy heap of poop near lizzy mouth! Suckd heaps of mud and poop thru motor then had to get out and push! Cut my feet up bad anyway once unstuck the motor wasnt pumping water! I endend up doin a mcgyver and sucking on that hose where the water pumps out. After a million mouthfuls of poop it came good and was flowing again! When i got home to flush the motor i noticed the watermaround the prop was litteraly boiling couldnt touch it! Im wondering if this is normal to be so hot or maybe sum gearbox damage. The boat seemed fine all day just so bl..dy hot when i got home! Any thoughts????

Post was ment to be high and dry lol

By the sounds of it you may have done some serious damage to the impeller. Dont run the motor and either change out your impeller or take it to someone who can do it.

Hmmmmmm frig!!! So it pumps water as normal but realy hot

lol ive never seen anyone give mouth to mouth to their outboard... usually a bit of wire or 100lb leader will do the trick - try that next time.

so its wasnt hot before ? have you only noticed it now? if its changed then i would definitely get it replaced - or do it yourself.
the water coming out of the leg is usually pretty warm though depending on the make/model.

Hi Jdog, there was a recent thread on this kind of impeller problem, where (as I recall), it was the water pressure from the hose/rabbit ears that 'pushed' the water around and not the impeller, but gave the impression the impeller was ok! I'm guessing, but you may still have some solid type muck in there still too.

Yeah on the 250hp Suzuki the water is hot after it sits there idling for a while !! But not boiling that's for sure
Motors aren't designed to be run for long periods of time on te ear muffs as there not getting submerged in water if your tell tale is still strong it may just be something you hadn't noticed before ??

Yea a cable tie and mouth to mouth got it flowing on the water as normal but wen i went to flush it was idleing funny and hot i should also mention i picked up some rope in the prop but i was on to that pretty quik! It was a fail of a day everything went wrong! So im pretty concerned as it was farkin hot i also noticed a bit of oil around the back of boat im thinking gearbox seal or the hyd steering i just installed! I will suss it out tomoro is a impaller swap a big job or could i manage it myself im pretty handy and have tools

Hi Jdog, if you are fairly handy, you should be able to change the impeller yourself.

did you end up sortin it out mate?

Motors also have a bypass for the thermostat that water rushes around once the temp gets up, had my motor overheating alarm come on at one stage, was after ploughing through some shallow stuff, turned out the bypass was clogged with mud and shell bits!!

Water still pumped ok through telltale and no overheat at low speed, only did it when cruising, maybe something similar to this has caused a water flow restriction somewhere!?

Motor is usually always very hot when you first put it on the earmuffs as well, especially the telltale, depending how long you have had it out of the water before you flush it, mine tends to cool down a bit after running for 5 min on the earmuffs!

But I would definitely check the impeller anyway, can get ripped up pretty bad by shell grit!
