What would you guys consider high hours of use for a boat motor, I'm talking 150+horse power motors.

Well i had a 225 Opti Max with 1086 hours on it when I sold it. It ran like a top for sure...  I have a 250 Pro XS on my Phoenix with around 450 hours and it has never had a thing wrong with it. SO my thing is Run it like you stole it and use good oil and have it service once a year.

Wow, I read initial post, and first 10 or so replies, people sure got off on a tangent.  Anyhow, I have heard of many motors over 150 HP going for 3000 plus hours.

I agree, the worse thing you can do to an outboard is not run it. 

The more you use them, the better they run.  

Also, with today’s fuel, a splash of fuel maintainer / cleaner in every tank keeps em’ running good!

On the question of hours, i have read many comments on the (hulltruth) the commercial buys that tow, ferry, comercial fish, get 3 to 5,000 hours on their outboards.  They like yamaha, suzuki, nissan, honda,.

They use their motors every day and do their required maintenance.  I think outboards need to be run frequently.   I believe long layoffs of time and lack of routine maintenance is a big problem maker for outboards.

Yes, same reason I traded my Merc. For an 50 E-TEC. Love the Motor, But when I looked for a new kicker 5-10hp. Everyone was made by Tiatahsu(sp) in Japan.So I kept my 96 5hp.Mariner,also made in Japan! No complaints at all about the E-TEC.

From what I heard,Mercury Marine built that plant in China to meet global demand.But I will bet that most of the engines made there are imported back here.When I priced out 50 HP outboards,Mercury was more than Honda equipped with the big tiller handle.Suzuki was decently priced,but no dealer close.And both Yamaha dealers here are a-holes.The Honda dealer sells lots of units to commercial users.I see many commercial fishermen on the Mississippi running Honda's with lots of hours on them.

I don’t mind buying engines made in Japan, but I will never buy another Mercury due to their moving some production to Communist China. Same thing applies to GM.

They both took American dollars, or tax relief to stay in the USA, and both did not hold up their end.

You are right 40-60 power heads basicallY Yamaha power heads installed in FonDulac, check in parts suppliers they are all the same. That is why I laugh when  the “EXPERTS” say Yamahas are much better then the Mercury Junk! 75 and above all made here .Smaller motors are all Jap,read the name plate!Even smaller Evenrude are made in Japan.

It may have in fact been been assembled in Fond du Lac but it was a Yamaha power head. At that time some HP's just a Mercury lower unit and case, some where all Yamaha painted black.

and here is the list as it stands right now: 

Mercury Outboards, 30 Hp and less, are made by Tohatsu in Japan. Mercury Marine builds 40, 50 and 60 horsepower outboard motors in Suzhou, China. Mercury also manufactures engines over 75 horsepower at its facility in Fond du Lac in Wisconsin.

Mercury has never made their own 30 HP 4S engine and still do not.
