Clearing weeds . Good advice

[Scott0321]

Just got mine back from the ten hour serivce and one minor issue. Apparently there was a fault code for the temp sensor they cleared. Local dealer claims it's fairly typical in these machines.

Apparently there were some weeds in the pumps that cause it to run hot. Not too hot so it flashes the light on the console. They were telling me if I think I've hit some seaweed or sucked up anything to go WOT and then pull the tether. It will make the boat lunge forward and likely wash / flush any debris out of there. Tried it last night and low and behold a clump of weeds floated out from under the boat. I'll do this each time I take her back for a rest.

:agree:That's the best way to remove debris. I hear so many members claim they go from forward to reverse... They forget that the engine is always turning forward and the reverse gate just directs the flow of water to make the boat go back wards...

How about?

Go backward as fast as you can- Pull the lanyard- shift to forward.
Sounds silly, But You never know!

hmmm

it sound like to me to have a motor running at 8000rpms and to just kill it is bad news.... i cant see how that would be good on the motor????

ok, I know I'm the newbie here and I understand the go backward then stop thrust thing, but the logic of shifting to forward eludes me, it to get the deflector out of the way?..

Forward has the bucket "up" so when you're moving backwards with the engines off the water flows reverse thru the pump and pushes the debris out the way it came in..

The best way is to bring a pair of swim shorts....

Strange how weeds could cause a 4-tech boat, that is cooled by heat exchangers, to overheat. The only theory I could come up with, is you ran the boat at at full throttle with a halfway clogged pump. I.E. you were not going anywhere fast at full throttle. That is theorsizing that the volume of water passing over the exchangers was not enough to cool the system, which in a lake, seems almost impossible to me, less bombardier is using wimpy exchangers. This is also giving it a worse case, high water temps at the end of july scenario.

p.s.speaking of 4-tech, might have better luck with that overheating question in the other section.

I think the idea of WOT and stopping the engine quickly is to stop the impeller and hopefully the waterflow will wash the debris off of the impeller since it has stopped and the water is still flowing past it. Makes sense. Kind of like reversing the impeller with the water flow.... if that makes sense.
