Whats my 454 Merc???
I have a Mercruiser 454 4barrel carb. Trying to see if its a Mag with Rec. ports or peanut. I guess its a Gen VI. Heres my serial #0K282859 I looked everywhere and I guess it can have either one on it. I dont want to remove intake and look at head ports. Anyone know what I exactly have?
Thanks
Thanks

I have older 454's and this is the site I use but nothing is coming up - maybe because your motor is newer. http://www.castingnumbers.info/site/search/859

According to this site a mercruiser block with your serial number (minus the 0 in front) is a 96-97 454 mag mpi. http://www.boats.net/parts/search/Me...998/parts.html

But this site says nothing about a mag. https://webapps.brunswick.com/litera...atureSearch.do I would get the block casting number if you can get to it (I am guessing the serial number came off of the carb cover?).

In your other thread you said that on the top it said 7.4L Thunderbolt. Thunderbolt is the ignition system. 7.4L distinquishes it to be a 310 prop shaft HP cast internal engine. If it were a mag it would clearly say 454 Magnum on top. This is assuming everything is all original as it came from the factory. Also the last year of the carb engine was '97 so it looks like your '98 boat got one of the last carb engines from '97.

That serial number range doesn't only cover mags. It also covers the 7.4L Bravo carb engines 1996-1997.
