Carbon Guard

I just found out that I have been over-proped and I do a lot of slow speed trolling.

 

I use XD100 but have seen on other forums that this can lead to carbon build up which, in turn, can lead to some serious problems.

My engine has 180 hrs and is a 2012. I have a new prop to make sure my WOT revs are correct.

 

Should I use Carbon Guard to be safe?

 

If so, how much and how often?

Thanks

 Overpropping is very bad for an outboard. I hope that your new prop is allowing the motor to run up in the 5800 rpm range or so. The top rpm redline for your motor is 6000 rpm

 

Because you are outside of the US and your gasoline quality may vary, it wouldn't hurt to use Carbon Guard in your E-TEC with all that low speed running.

Re: Carbon Guard

Thanks Bill,

I'll make sure new prop gets the correctt rpms at WOT.

I have just ordered the Carbon Guard.

 

I have also seen reports on stuck exhaust valves. I cruise around 3500rpm (40km/hr) for economy and comfort. I have also read carbon can cause a stuck exhaust valve (expensive repair) and that my engine should also be run at higher RPM frequently to open the valve and prevent sticking. The valve olny opens around 4200rpm.

 

BRP has added a grease fitting to newer models to prevent sticking but cannot be retro-fitted to mine so I want to try and prevent the problem.

 

Thanks Again,

Visit www.etecownersgroup.com .  Someone there modified his 115 for  a grease fitting a while back. You may have to use the SEARCH function on that site

Thanks Bill Smiley Happy

 

Will Carbon Guard and short runs at high rpm to open the valve help to prevent exhaust valve sticking?
