View Full Version : Is a115 hp big enough for a Fisherman 1800?????
Need sopme help from you guys. I have found a Lund Fisherman 1800 used (2002) with a Yamaha 115 4 stroke. Does anyone else have that combination?? Seems underpowered since the boat is rated to 175. Any input will be appreciated.

I have a Tracker 19' 7" Open Walleye Boat (Aluminum) with an OMC 115 and get 38-40mph at WOT...So, you can decide for yourself how well that performs against your desired speed...

Tom,
I have a 97 Lund 1775 Pro-V Dual Console with a 115HP
Envinrude Intruder which is well below the max hp rating
of the boat. The 1800 Fisherman is longer but weighs less.
I would think you would run 45 mph with two average sized
guys with 30 gallons of fuel. If your 200 + lbs like I am
you may be choosing your partners. Two 200 + guys may slow
you down. That when you will wish you had a 150, like I do
some days when I have my wife, 2 kids plus 2 neighors on a
tour around the lake. If you intend to use the boat in
tournaments, I would not get it. Max the power on any boat
you get. I bought the 115 hp mainly because my wife would
not let me get the 150 hp. She the boss, and she paid for
half the boat. Good luck on your choice, BATMAN

I have a 2002 with a 125 2+2 and it is fine for everything I have wanted to do. I can ski or tube behind it, can troll or speed across the lake. I have been up to 46 gps with full tank of gas and two guys in it with full gear. Running with the family, (5 people in the boat) I can still get 40 - 42 and have no problems.
On a recent trip to MN, a friend of mine brought his brand new 1800 with him. Low and behold, he had a 115 4 stroke on it. He could keep up with me with no problem. Granted, he had about 150 lbs less weight in his boat, but that kind of weight is not going to make much difference. The 115 is definately quieter compared to my 2 stroke, but he also spent about $2000 more on his setup. Other than the engines, we both had them set up the same.
I know many people are putting 115's on the 1700 around here and are having no problems either.
It will come down to what you intend to do with the boat. As I did not see him pull anyone on a tube or skis, I can't attest to the performance there. However, if you are running from this side of the lake to the other and anywhere in between with some trolling, I am sure it will do fine for you.
I know on this board, everyone says max it out to the maximum rated amount, but for some, that is not feasible. Also, if you pay less up front, you will expect to get less down the road if/when you decide to sell. Some may say it will be harder to sell with the smaller motor. As this is a new motor, that will be hard to determine for a few years. If you are not running in tournaments, a smaller engine will suffice for the average fisherman/boater. Here in Iowa, I have seen many 1800's running with a 125 Merc 2+2 on them. I am happy with mine and have two other friends running the same setup. I was surprised to see the 115 on an 1800, but after watching him run all week, was impressed that there was not that much difference between the two engines on the same boat.
Hope this helps.
A 115 on that boat is a bit underpowered. A general rule of thumb is to put at least 75% of the max hp on a boat. For an 1800, rated at 175hp max, thats 130hp. The 115 seems more reasonable on a 1700 which is rated for 150hp. The 1800 weighs about 200# more and has a 3" wider beam too. I would suspect that combo to be slow to plane and max speed in choppy conditions around 35mph. Underpowered boats can be difficult to resell, but when you're buying this time of year you can usually get a heck of a deal! A buddy of mine has a 1700 Fisherman with a Honda 115 4stroke and it tops out near 40 on smooth water. I know another guy who has a 135 opti on his 1800, I don't know his top speed but he is pretty happy with it. At the other end of the spectrum-I run a 1800 with 175 Opti, it tops out about 55 gps with a normal load and 2 people on board. Good luck with your choice.

If you don't care how fast you are going and are going to use it for fishing the 115 will work. If you are going to ski with adults and you will need a a min of a 150hp. It's a nice big boat....
Thanks for the input and reassurances. If you guys think the 115 will besufficient, and it sounds like it will be, then I'll have to think a little harder. Thanks again, and hope to see some of you on the water. I've only been on this website for a month or so, but have found it to be the most reliable and educational. Keep up the good work...Tom
Take a look at the Yamaha Website. They have preformance evaluations on many different set-ups. http://www.yamaha-motor.com/products/otb/perfbull/performance_02.html
They do not test the 115 on a Fisherman. They do test it on a Crestliner Sportfish (pretty smilar boat in lenght weight and beam) Speed at WOT with 2 people was 41.8 MPH on GPS.
The same boat with a 150 2-stroke under the exact same conditions was 49.8 MPH on GPS.

I was testing with a friend 2 weeks ago. His 1700 Fisherman has the Yamaha 115 4stroke. Despite trying several props and a whale tail, the boat was consistently slow out of the hole (7-10 seconds) and the best top end we could get was 43MPH with an 13x18 pitch SS prop @5600 RPM. More power please! (if you like that kind of thing)

My buddies brand new 17'10" single console Alumacraft Magnum(?)(not a heavy boat) will only run in the low 40's w/ a 19" SS prop and a 115 hp
Yamaha 4-stroke. That's with just him and almost no gear in the boat.

I am running a four blade 13 3/4 X 21 prop. Water was like glass. Got right up on plane and away we went. This is not a consistant speed, but it did hit it.
When I first got it, I had a three blade 13 3/4 by 19 and top end was 42 wot.
Normally, it is running 40 - 42 which is still fast enough for me and to pull skiers and tubes for the family or get across the lake to hit that special fishing spot.
I normally cruise around 36 - 38 mph gps, seems to run great in that speed range and does not use as much fuel.
I have noticed when I first take it out, it does not run as fast as when I have had it funning for an hour or so.

A general rule of thumb is 75 percent of the max hp. rating. A friend of mine bought a fisherman rated for a 175 with a 115 and it plows water with a full load. He is not real impressed with the overall performance.You get what you pay for I guess. My 02 cents
I have been in several different fisherman 1800 with the 115 4 stroke engines. The different boats, all had slightly different propellors.
In general the top speed - with the typical loads, that were encountered by a pair of average fisherman was 36-38 mph.
In a heavy chop - the folks generally were more pleased, if they went to a lower pitch propellor. The lower pitch propellor, would quickly kick them up on plane, pop up the bow - but would further lower their top speed to 32-34 mph.
None of the folks that I fished with, were speed demons; and really loved the starting, quietness, and overall smooth and very capable operation of the 115 for the fishing application.
None of the owners were sorry that they had this engine on their boat. Some of them said that it would be nice to go faster; but none were willing to put up with the noise of a 2-stroke for the added speed.
Take care

I bought a 1700 Lund Fisherman this summer with a 150 HP ficht engine. I am very happy with the hole shot power and top end speed. I am new to this form however believe it or not with a non stainless steel 3 blade 19 pitch prop I can get 53 mph out of it trimmed up.
This is according to the Lund speedo but at other than top end I think it is very accurate with my gps.
As to whether the 115 is enough I would suggest that you should seriously consider at least 150 hp. I have bought other boats with not quite enough hp for the boat and regretted it for the life of the boat.

I have a 115 on a Mr. Pike 17 and would not reccomend it on a 18' Fisherman. If you can afford it, go with a 130 Honda or 140 Suzuki.

We've been running a 75 Honda on an 1800 Fisherman for four years now and are very happy with it! Yes..it's a bit slow out of the hole, but has no trouble keeping the nose up and actually hits about 34 mph (gps). It trolls so nicely that we don't need a kicker and it just sips gas. For serious tourney fishing, I'm sure you'd want more speed. But for the serious weekend anglers that we are..it suits us fine! Good Luck & Good Fishing, Sluggo (Chris)

The 115 on the 1800 Fisherman may suit your needs, both financially, as well as on the water. I made the choice to put a Yamaha 150 HPDI on my 1800. Huge upgrade, but I've enjoyed every moment with this combination. Consider the waterways upon which you will most likely use your boat. The larger, rougher, more current etc.., the more necessary a higher Hp rated engine becomes. Top speed was not an issue for me, as most of my travel is at 3/4 throttle or less.

The 1800 Fisherman with a 115 four stroke is the most popular model we have sold for the past several years.
Folks love them.

Something no one else has mentioned is resale value. As I was told, you have better resale value if your motor is closer to the max HP allowed by the boat's rating. Supposedly has something to do with versatility.
I matched a 2002 115-HP Suzuki 4-stroke to my 1675 Lund ProSport. I've never regretted going to the high end. In the one & only walleye tournament my wife & I were in this year, we drew the "#1 out of the hole" position. It was great fun to full throttle the motor to get to our "honey hole." It would have even been better if we could have caught a few fish from it!
If you max out your HP, you don't have regrets on wishing you had a little more. With a 17 pitch prop, I can troll crankbaits down to 1.5 mph. I haven't seen anything else on my waters that made me wish that I had done anything diferently (doesn't mean there isn't something better elsewhere than what I've seen in the "Land of Enchantment.")
