Offshoreonly.com - nor tech 650efi

Ihere they sond great I have the 2nd set goig in my 43 with tripple power the first set is in a new 39 v hull running high 90's but fell a little short on the dyno.Absolutely no problems from out of the box and in case anyone was wondering no blowers and 89 octane.Maybee mercury should take a lesson from ron potter why use a blower with high octane and 100 hour rebuilds when they can build simple h.p.that can run 500 hours without a rebuild and very little electronic components which is proven to let you down and add blowers and bravos to that equation and we all now the out come long before even 200 hours.The new 650's will dyno at 660hp and make simple horsepower that believe it or not has been around for decades.By the way my first nor tech had tripple 625's naturally aspirated and Isold it with 200 hours and did only poker runs with it never had a mechanical failure.I don't think I have even heard of hp 500's with that record and as afar as I know there were many 625's with over 300 hours that never skipped a beat!!!!
