300 G2s temp problem ???

I had a steering issue  on E300XUAGD Ser # 05484006 and it turned out to be a sensor.My dealer dropped it in the water yesterday and I drove it back to my dock.I saw the temp go past the arrow in the middle of the temp scale for the first time ever on both my 300s. The one that had the sensor changes went between the arrow in the middle of the temp scale and the red at the end of it.I do have the cooling kits for the #6 pistons on each engine and my dealer said it has the latest updates.
I ran around 3600 Rpms for about 20 minutes and no codes or horn came on but saw the temps running higher then I ever have.When I go off a plane and ran around 1000 Rpms on both to my dock for for around 15 minutes and the temps we cooler then they usually run at the Rpm so not sure if I have a issue.I have around 40 hours on each engine.I never got a horn go off or any codes at all.I took these at the same time.015.JPG011.JPG

Re: 300 G2s temp problem ???

Engine temp varies widely with water temperature, especially during the hot summer months in many areas. As long as the alarm does not sound, the engine is OK and normally will run warmer just before and just on plane.

 

If you are concerned and depending on the hull, often the higher flow water inlet screens allow more water into the engine, especially if aerated coming off the transom or with transducers or thru-hull fittings too close.

Re: 300 G2s temp problem ???

There is a known issue (known by BRP) in the 3-4K rpm range the temps go way up. In warm waters they cause faults. BRP witth cover the high flow intakes under warranty. It does this on my boat also but my boating waters are very cold so they stay in the 170F range, If you are above or below this range the temps cool off. It has nothing to do with areation of the transom or tranducer.  This would affect the temps at all ranges and BRP wouldn't be coverinbg it under warranty. The is a boat load of people in G2 owners facebook forum who have made this warranty claim, every kind of hull imaginable. According to Joe Pekara at Barnicle Bills they replacemnt part is the largest 1/4 inch intack screens.

 

 

 

Try it. Accelerate and watch the temps rop.
