A fairly skilled marine mechanic should be able to install this new header system, on a single, in about 2.5 hours, with time to spare.

Do we have to wait for the ice to melt?

I'm Carl C on Donzi.net. I saw no gain from my $5,000 CMIs. They were a beotch to install and rendered my Q&Q useless above 3,000 rpm. They look good though. You guys are right, 5,300 would be well into the rev limiter. The shorty gave me a solid 3 mph gain. Hi Frankie.

Sell the motor and then buy a new one will cost about as much as CMI exhaust. I had a 496 in a Nordic Heat and I sold the motor and installed a 500efi for $2000 and gained 8mph and a lot of torque.
