Has anyone

Ever heard of a 275HP 25" Mercury Cosworth outboard motor?
What do they weigh,are they hard to get parts for as never heard of one prior.
Placing it here as it was referred to as a high preformance motor and in main forum would be covered up shortly.

You may have to wait until Charlie gets back to get an answer... I've heard of Mecury and I've heard of cosworth and that's the best I can do for you.

Ahhh hah.... found this...

It is the 3.4 liter V6 Mercury/Mariner Engine block with certain mods to make it a Cosworth Engine (blueprinting, I think). This 3.4 liter engine has been around since the early 1980's and is an great motor. The 3.4 liter came out as a 300hp in 1982 or 1983 and was the same motor(they dropped the hp to 275hp) until the mid 1990s when they dropped the 3.4 liter from the line up in favor of the 3.0 liter. It was heavy 575lbs and a very strong runner even not being a Cosworth. I heard that it was one of best motors in turn of lack of warranty claims. I like the 3.4 liter because it is so big it alway draws attention, but then again that why I love the v8 3.6 and 4.0 liter OMCs. The biggest draw back to owning a 3.4 liter Mercury is the parts are very hard to come by. The best bet is to buy another 3.4 liter to use for parts. Just my 2 cents

Just window shopping a bit hefty and aba has a 250 hp cap I think have to recheck the regs,as for what color the motor is, can repainted what ever to suit.,Wouldnt bubblegum pink look swell.

Power ta weight, hi performance, parts......They suck period. They went away in tha late 80's. There were a few "replacement" motors available later on. They tried ta build a hot rod in tha 3.4 rated at 300 but would not turn tha rpm and live. I will give 'em this though. They are "stump pullers" as far as tha goobs a torque they make at lower (compared ta a stem winder 2.4/2.5) rpm. Compared ta todays motors they don't stand a chance. We went through a few back in tha '80's. JMO..........T

Unless you just want to have something "different" I would look other places. I remember reading a "shootout" between these and the V8 OMC. The OMC gave that big Merc a major @zz whoopin.
