150hp ob performance survey

[Skools Out]

yeah i might want that ol 175 but, from what i've read the best on the market is Yamaha. I've got 2 yamaha's and never had a seconds problem with them. I did change the reeds to Boyesen Reeds. Little better fuel mileage. If i could i'd put Yamaha's on all mine but they are higher than OMC. I've had a few Merc's and they just aren't that well built of a motor. They have alot of electric box and oil injection problems. Are pron to throw a rod and knock it through the block. Merc's will dollar you to death. I've rebuilt a couple Merc's too. But I've got a few friends with the newer Suzuki 4 Strokes and man I want one of those. My next new motor will be a Suzuki. Now the Honda is a great motor but hate to say this cause RAP will be up tonight worried lol. Honda's have a major issue with an Aluminum washer under the power head that if it gets wet it will start to eat away and cause an oil leak in your crank case lower seal. You can replace the washer but it will only give you time till it gets wet. Requires removing the power head. I talked to a Honda mech. he said they were trying brass ones on some at the shop he's at Shop is "Wheels & Keels" of New Port NC. So far the ones he fixed were still going strong with no problems from the brass ones. The OMC products are great for lasting but they use alot of fuel and they need the oil injection removed on the 97 and older models. Are great motors inside. Rarely see them throw a rod through a block. Strong motors.

I have a 150 yamaha and it tops out at about 42mph @5200 rpms . I am happy with it . But , I'm thinking about a repower with a new 2004 150 . Ed's has them for $6990 . I just need to find a buyer for my current engine . As much as I would like a new evinrude I can buy a lot of gas for that extra $4k !

Normally, I would be up all nite, but I got fever for a 200 E-Tec that's gonna be squelched in only one way...I'll have the Honda paid off soon, then off she comes...build the transom up to a 25''er and ZOOM!! ;D...

My numbers are exaclty the same as Labii's. And I too am a happy camper 8)

Funny thing though, I can't tell a top end difference between a light load and full load?? Seems to hit the same top end regardless ??? Not compalining, just puzzled :-/

Also, I was surprised how quiet the newer Yamaha 2 stroke was. Heck, my old 1975 Evinrued 70hp was louder than it! But, the 4 strokes - you really can't tell they are running at idle! It beats all!

Chesapeak 724, bought a rebuilt 84 Johnson 150 hp. still in the break in and finding the right prop. 30 mph. at 5200 rpm. with a 15 x 17 alum. prop. Need to get another 3 or 4 hundred rpm ? Reelapeelin has the right engine picked out ;D, I don't care for all the moving parts in the 4 strokes and maintenance adjustments you need to do. most all of the new 2 or 4 stroke engines will get you 25 to 4o% better gas mileage. Spend a little more now and save big time later. Crusher

[reelapeelin]

Yeah, He breezed through... ;D...

crusher that's all you want to turn an 84 150 OMC they are cross flow motors they are peaked at 5300 the newer loopers will only turn 6200 but thats not the best idea on them.

he you want the bad news about a 4 stroke? they are to quiet when you are fishing they are so quiet that they don't attract fish. all the guys at the coast like the fuel but they have a small 2 stroke on them to crank while out in the gulf stream so the noise will attract the fish.

I've got a Johnson 150 ocean runner,maybe the 10th outboard in a boating career that spans about 20-25 yrs. I, personally, have never had any problems w/ any of my OMCs that have ranged 35-200 hp.They always start always ran and never let me down. I did have one Merc, a 90 hp in line six cyl. and "most" of the time it ran well...however,it was kinda loud or "tinny" sounding,had to have the carbs rebuilt,replace the power packs,lower unit redone,starter replaced, and it was always tempermental when starting...it was, more often than not, harder to start when it was already warm. I do think Merc. makes a good outboard,I cannot bastardize their entire line of motors based on my personal experience but it did sorta make an impression on me. Prefference toward a brand of outboard gets in your blood and most people stay where they are comfortable, and that for me is an OMC. I don't think anybody is here to piss off people with this brand of motor or that brand of motor...it's not what this board is all about.Back to the original post reply...I have recently put on a stock 3blade aluminium 15x17...cruise about 30 at 3850 RPM top speed is about 38-39 at 5200RPM...have'nt got it to redline yet[5500]
