Well I finally did it and traded my 312 for a 382 and now have questions since I left the dealership. It has external mufflers and captains call. Is there a reason to have both? I will be boating on a local lake and the Ozarks, and think I could do without the mufflers. It also has sea strainers and I am not familiar with there operation, is there maintinance to them?

Formula has always wanted to be a good citizen and not build loud boats,hence the mufflers with CC. But it is a bit of overkill for some.If local laws permit it,just replace the mufflers with straight thru tips from an online vendor and sell the mufflers on E-bay. You can also cut the baffles out of the mufflers with a die grinder,but it is a big job and may discolor the finish. Most of our customers just buy new tips.

Forgot to mention that the 500's have a "speed switch" that opens the CC at about 2800 rpm,so if you replace the tips,you will be loud above that rpm and cannot close the diverters even if you want to. Just another thing to consider.

heres some pictures.
I had my boat on the water for the first time today and everything went well but one red light. I don't know if the two red lights next to the tachs in these picures are stock and I am not sure what they are for, but the port one comes on at about 3000 rpms and stays on untill it drops below again. All the fluid levels are good, temp and oil preasures are good. The only thing I can think of is that they are rpm red line warnings and this one is not set right. Does anyone else have these and can help me out.

Your sea strainers should have clear lids. No routine maintenance required other than to check if there's any crap in them. A blade or two fo grass will eventually be ground up; no harm. but a good-sized chunk of plastic might restrict the water flow. Next time you're in the water, but before you start the engines and get them hot, practice opening them up and putting them back. You'll be glad that you did if you ever have to do it for real and the engines are roasting hot. They're down deep....
