yamaha 4-stroke?

[Dean B.]

Planning on buying a Lund 1700 Fisherman. Problem is , not sure which motor to go with -115 Evinrude Fight or 115 Yamaha 4- Stroke. Is the Yamaha too heavy? Also had a dealer tell me that the 4-Stoke would need valve work about every other year. Others say go with Mercury. If anyone has any input, would appreciate it.

Dean, I was reading this morning that the Yamaha 115 weighs in just under 400#. I have a '99 Merc two-stroke 115 on my '99 ProSport 1700, motor weighs in at just under #350. #50 doesn't seem like a lot, although it is in a critical location, of course. 4 stroke sure sounds enticing....Good luck on the water. John.

Is this the new fuel injected 4 stroke? Curious
what kind of a price did they quote you?

I put my NEW 2000 1700 Fisherman in the water Sunday for the first time. I think that it's going to be a great boat for what i like to do.

I have a 115 Johnson on her and the motor is working like a dream.

The Johnson weighs in at 319 pounds. I don't know how the boat would handle with any more weight, on the back end but she is rated for a 150 and those weigh in at about 450 pounds.

That 115 Yamie should work just fine on her.

YOUR GOING TO LOVE THAT BOAT..

GOOD LUCK

Yam F-115 not too heavy. We have sold several 1700 w/ F-115 Yam & they run excellent with the stern width and IPS hull of the Lund.
That is the whole idea behind the width (of the BOTTOM of the boat...not just wide at gunnel) of these new Lunds.
By the way the F-115 runs this boat every bit as well as a 2-stroke 115 will.....and on a lot less fuel.
The boat is rated at 150 hp.

Hi Terry. You said that the 115 4 stroke will run on "a lot less fuel." What does that mean in real terms. Not trying to be aggravating but I hear alot of these claims on 4 strokes but it seems there is a difference between "alot" and "some." Yamaha does claim some fuel efficiency increases in the 2000 catalog, but not "alot." I have seen some test results that indicate, depending upon the horsepower class, absolutely no difference in fuel efficiency except at trolling speeds. Bass & Walleye Boats just did a review of 25 hp motors and some of the 2 strokes showed greater fuel efficiency than 4 strokes at cruise speeds.

Please forgive me for being what may appear to be retentive, but alot of people come to this site to search for factual and accurate info on boats and motors.

Please feel free to correct my thinking if I am in error.

Last year on a fishing trip up to Rainy Lake, I burned about 25 gallons in my 1999 Yamaha F100 on a 1999 Lund 1700 Angler SS. Another guy in our group burned about 22 gallons in a 1985 50 hp Mercury on a 1984 Lund Angler. We both did about the same amount of running around. This was over 5 days of fishing.

Thanks for the info, John. Did you guys do much low rpm trolling? The 4 strokes are far more fuel efficient at low rpm trolling speeds. Also, do both boats weigh the same? A 100 hp motor will push a boat far more efficiently than a 50 hp motor will.

My thinking is that if a 115hp 4 stroke is mounted to one 17' Angler and a 115hp 2 stroke to another, then the 4 stroke will be "alot" more efficient than a 2 stroke at trolling speeds. However, the story changes at cruise speed. Fuel efficiencies will be somewhat comparible. Some 2 strokes, depending on the manufacturer, may even be more fuel efficient.

Please let me know if you think my reasoning is in error as my plans are to mount a 2 stroke main and a 4 stroke kicker. I thus enjoy the cost and power-to-weight ratio benefits with the 2 stroke and the fuel efficiencies and quiteness of the 4 stroke.

Thanks,

I trolled about 20% of the time and the other boat a little less. My boat is definitely heavier, at least 200 pounds. I went with the 4-stroke main motor because I didn't want to worry about the oil injection system although they are very dependable. Also, I didn't want to get a kicker.

[TerryMac]

Sorry...misleading, the way I said it.
We find the F-115 to burn about 30% less than a Yam 115 2 stroke....at worst .
The Ficht is also very economical...but this Yam
is where I would put my money.

I HAVE THE 1700 FISHERMAN WITH A F-115 YAMAHA WITH A 17 PITCH PROP AND A 9.9 YAMAHA 4 STROKE AND I'M RUNNING EMPTY AT 46 MPH AT 6000RPM. WITH THE BOAT LOADED AND FOUR PEOPLE ON BOARD RUNNING THE BOAT I'M BURNING JUST UNDER 1 GAL PER HOUR. USEING BOTH MOTORS DURING THE 10-20 BREAKIN. AS I'M STILL LOGGING HOURS. WITH A 19 PITCH PROP THIS SHOULD INCREASE TOP END AND ALSO GAS MILAGE. HOPE THIS HELPS. LOVE MY BOAT.

[Flip South Dakota]

What kind of speed do you figure you will get, with a 19 pitch prop on her. I have a 19 on a 115 Johnson and my dealer is hinting at maybe hanging a 20 pitch Raker 3 blade on the motor.

I was out Sunday for the first time with her ad she seams real quick. I haven't gotten to the WOT point yet though.

That boat gets into a plain very fast. The motor holds the boat in a plain at about 2600 rpm.

Any info you have would be great. Thanks in advance..

I'm not sure, but I'll be ordering a spare 19" as it will lower my rmp at the same speed. As I don't want to over rev her. Using the 17" for water sports and the 19" for early season fishing.
