That's some pretty fancy SS trim your shop came up with! Should hold up better than the original aluminum extrusion.

Hopefully they will install a good water separating filter like a Racor with a bowl on it so you can check it for water. The newer motors have a filter on the motor with a water sensor that will provide a warning on the I-Command gage, but I'd rather catch the water before it gets to the motor! That gage will also display water temperature. These motors run pretty warm at low speed, up in the 150-160F range, for good combustion and to help prevent plug fouling. Salt deposits start to form at about 165F so they push it pretty close. Temps drop to about 145F over 3500 rpm.

I would definitely use Marine Formula Stabil, Startron or the like ALL THE TIME, as today's gas will start to deteriorate pretty quickly otherwise. You might consider running a 4B prop on that rig, as it will provide extra blade area for more low speed thrust for towing or planing with a heavy load. The extra blade will also provide more stern lift to help you stay on plane better at lower speeds. My old "115" was only about 90 hp at the prop, and that new E-Tec is probably a little stronger than that, as BRP appears to be sandbagging on the power ratings. A 13 3/4" dia. x 15" pitch 3B SST was the perfect prop for it with the 2:1 gear ratio; if the new 90's have a similar gear ratio, a prop of about that size should be a good starting point for your rig. You probably won't run over 32-34 mph, so 15" pitch should be about right. With a 4B prop you'll want less diameter, maybe something in the 13 - 13.5" range, but the dealer should have several different props you can try. Good luck with the new motor! Let us know how it works out!
