Is this a GM small block or the Merc produced piece that replaced it sometime around 2015?

I am sure this is an all in house Mercury block, etc. so that when you have an issue you get to buy parts from Merc for 10 times the cost of normal sbc parts.

would be cool if they mention cubic inch and other particulars. Just mosrky marketing ‘hype ‘ terms at this point. Not that it matters i guess because way too much money for the end result. Really seems they hate inboards and i/o’s and wanna just churn out outboards. IMHO |
Pretty sure I could build 2 650 hp BBC for the asking price......:D

Which the new 2015 up MERC 6.2 seems to be a near identical copy of. 409 Spec Sheet

The new 409?
I didn't find any dyno charts or torque specs on the new Quicksilver 409. Because if the 409 makes 650 lb-ft at 3600?? We definitely need to see that.

I also noticed that the Quicksilver 8.1 and the 540 Mag stroker are no longer available. Looks like this is your Mercury sourced replacement for big blocks with a warranty.
Mercury still has the 8.2L/502 in³. Uncertain if they'll sell those for repower or not? |
