Hi,
I'm building a new boat this year, original plan was to put the new 8.2 liter in it, and figured may as well go with the 430 HP model... A friend who works on these things, but said he hadn't dealt w/ the new ones yet voiced some concerns over the cat's on the 8.2. Being a new boat I'm supposed to put a current year model emissions engine in it, which basically means they have cat's now. His concern is them getting wet and failing, and being expensive to replace. His recommendation was actually get a re-manned MPI from the year before since it will not have the cat's (which is bending the rules, likely doesn't really matter but I'd still prefer to have things 100% unquestionable)..
Does anyone have experience with this engine or the cats and is it good or bad? Does anyone know if I was to have problems if there is a way to delete the cat without making the engine flake out? You'd think there would be some way to trick the engine into running fine without it, but maybe not.
Another option I could exercise is the 520 HP (lowest end Merc racing) does not have the cat, I really do not need the extra power but essentially it's a souped up 8.2 bored over that comes with a 2 year warranty. Does anyone have experience with these? Any idea of they operate similarly as the 8.2 would efficiency-wise when run down in the bottom of their range? With the 8.2 it's likely I'll be cruising at only like 2000 RPM, kinda wired thing to do with a racing engine, but maybe it might be just as good as an option without any sacrifice to reliability and more bragging rights when run to it's full potential. The cost difference is only like 3K between the two.
Thanks in advance!
Jon
