Yamaha 150hp - 2 stroke or 4 stroke


JVAllstar

Recommended Posts

I am buying a new 21 foot Starcraft fishing boat, and I have a choice of which outboard motor to buy. I have had great luck with my current 115hp Yamaha 2 stroke for the past 10 years. The current specs of my new boat call for a 150hp. I hear a lot about the new 4 strokes, but I have had such good luck with the 2 strokes I'm hesitant to switch. Any suggestions?

We upgraded from a 135 Mercury to a 150 Honda 4-Stroke. Haven't had a bit of engine trouble yet, starts on every turn, and it's nice and slow as well as quiet, great for trolling.

If you've got a choice, I'd definitely go with a 4 stroke.

there probly gonna be some trade offs. The 2 stroke is gonna be faster and Quicker and lighter, On the other hand a four stroke your gonna be able to troll slower a be Quieter with better gas milage.

I had a 115 Yami 2 stroke on my last boat (7 years) and have a 150 4 stroke Yami on my new boat..Would I go back to 2 stroke? No way....Quiet, no smoke or gas smell, a tank of gas lasts forever..I could go on and on....

The F150 (4-stroke) has a great reputation.

Lighter and quicker plane with a 2 stroke is the argument you will hear. Lighter - yes but by how much, 100 lbs maybe, when your loaded boat weighs 4,000 lbs are you really worried about another 100 lbs (2.5%). Quicker plane - yes but again by how much? a second or two.

IMO the benefits of the 4 stroke (the main one being lower fuel costs) out weigh the benefits of the two stroke.

In that size motor I would go with the 4 stroke all the way. Like said above the 150 Yamaha 4 stroke is a very reliable motor and great on gas. Trolls pretty good too but you may need a drift sock at times.

With gas prices the way they are I would get the 4 stroke. Plus they are nice and quiet and easy to winterize and change oil on. Usually only have to do that once a year so no big deal there.

Another vote for a 4 stroke. I went that way for the first time this year and am very happy. The quiet alone is worth it and when you add in the ease of starting and fuel economy, I don't think you'd be sorry.

My father in law has a 4 stroke yammi (either 150 or 175 can't remember) on his Ranger, and it is really nice. Smooth, quiet, and reliable.

On that big of a boat I'd go with a 4 stroke as well... a 2 stroke on a 21 foot boat isn't going to give you many advantadges.

      Hi all - new to the forum.  I live in NE Wyoming and am an avid fly fisherman.  While I love fishing for trout out west, warm water species on the fly is a blast.   Me and a buddy are headed out this coming weekend for a BWCA trip.  We have a couple of days on the front end of the trip to fish.  I'm planning on towing my drift boat from NE Wyoming and have spot picked out in North Dakota to float for smallies on the fly.  I'm looking at trying to get an additional float in somewhat near Ely before our entry into the Boundary Waters.  It's a 16' drift boat and doesn't really draft much.  I'm planning on having a small trolling motor just in case I need some additional power.  Looking mainly to target smallmouth and pike.   I've looked at a few areas to float, but wanted some advice.  I have a few options that I think meet what I'm looking for:   1) St. Louis River near Hoyt Lakes.  Looked like there are couple of access points to launch and take out below Hwy 110 2) Cloquet River - Hwy 7 to the mouth. 3) Bigfork River - From Ivan Crawford to Reedy Flats   Can anyone provide any advice these or provide any other recommendations?   Thanks in advance!

      I have been doing pretty good bass fishing locally.  A lot of numbers, but lacking in really big quality fish that I have caught the last two seasons.  Biggest I could catch this season so far is 18 inches.

      Welcome to the forum. Downriggers work best for suspended fish in deep water. Most river's are shallow and rocky. If you want to fish the bottom in a river a bottom bouncer might be best to not lose a lot of expensive gear. Imo. Good luck.

      I have a Cannon Optima and Iam anxious to try downriggers for walleye.  There is a bottom tracking feature on Optima.  I think most walleyes are close to bottom so I think it is a good tactic.  I am, however, nervous about using Fishhawk XD4 with on river.  A screwup would really be expensive!

      i'm not real involved yet. my first meeting. long story but my parents belonged to it years ago. after the cabin lake had the 2 consecutive years of severe winterkill i dogged the heck out of the fisheries people in grand rapids.🤭 i found out through the watershed assoc they talked them into restocking sunfish and bass into the lake. they did that this past june. so i figured for the 15 bucks join!!!!!   my next battle is with the township......🤣 trying to get them to grade part of our road going into the cabin!!!!! i already sent the letter but havent heard from them yet. since i've retired from being a union thug.......i gotta pick a few battles to keep my skills sharp!!!!!!!!🤪🤭👍

      That's awesome that you are involved in that! I hope you have a good trip up!

      I'm heading up sometime the last week in Aug . I joined the Jessie lake watershed assoc and they have a meeting on the 27 I want to attend.

      Definitely in the dog days of summer. Catching a few walleye here and there on the river. Hasn't been too hot which makes me hopeful for an early fall fishing season. I'll post more when the fish turn their feed bags on and the leaves start falling. Until then I'll just work more and get winter gear ready

      Word to the wise. Never click on a Bot post with a highlighted link!  Unless you want cuddies on your system! 😛
