Well aware, I've mixed it myself before, however there is a volumetric limit and adaptation range of the controls that can be exceeded by extreme blends.    Adding 100% toluene to 87 to get a tank of 91 would be extreme IMO.   

I think that is definitely more true of ethanol than toluene due to the lower energy density of ethanol.

If I did my math correctly, raising 87 octane to 91 octane with toluene (at 114 octane) requires (91-87)/114 = 3.5%, or 4.5 ounces per gallon.  So one gallon of toluene per 28 gallons of 87 pump gas.

Crew,

When I click the boat from neutral into drove, I can here a noise in the vdrive or tranmission area. It's sounds like a fan blade barely hitting on something. It only happens in forward gear. When I accelerate it goes away. The noise doesn't happen in neutral either. My friend looked it up and thought it might be a damper plate. Any help is appreciated 

Inspect the housing of the strainer, not just the cup! I had this crack one winter that I forgot to drain the strainer. I replaced the cup but still had water suction issues. Inspected further and found this. Once replaced I had no issues. 
 

Before taking it to the dealer I would also buy a gallon of coolant and check to see if you can refill, run for a bit and refill again. There is probably air in the system. I also had a leak from the coolant cap at @csleaver mentioned that caused low coolant. Never got an over heating alarm but had a lot of fluctuation. I ended up adding an entire gallon of coolant over a few fill ups & runs. 

When going back for the second time and removing it successfully, what kind of wrenches did you use and where did you place them? I can find anywhere good to hold the fitting pipe without damaging it by too much grasp force.

The RC cover goes over the module that is in the port rear compartment. Might not have been snapped on all the way.
