4 stroke? 2 stroke?

16 posts in this topic

I'm thinking about buying a 14 footer (just the boat and trailer, no motor) that's rated for 15 hp. and if I get it, (which I'm about 95% sure I will) I'm trying to decide on a 4 stroke or a 2 stroke. What can I expect for a top end speed difference and does anyone know what the weight difference is? Thanks!!!

That was my same dilema a few years ago.. I say go with a 2 stroke!.. because weight is SUCH an issue with a small boat.. with you in the back as well.

No doubt 4 strokes are quieter etc.. but for a small boat.. I'd say weight is more important.. compare weights.. and get a long hose and put the tank up front too. Not sure which is more efficient.. but I sure get a lot of long days on a 5 gallon tank!

I decided on the Johnson (Bombardier) 15hp 2 stroke. I LOVE it! Always starts right up with a pull or two.. even after the long winter storage.

Mod the boat too... I added a deck.. carpet.. 30-55# transom trolling motor.. the latest electronic gadgets etc.. you would be amazed at how great a 14' can be for fishing!

If I was to fish alone my whole life.. I would keep my 14' Lund the way it's setup... the only reason I will get a bigger boat is that my young kids get bigger everyday!

I have a 14 foot lund with a carpeted plywood floor, livewell and storage compartment. It must be pretty heavy as 14 footers go. My outboard is a merc 15 4 stroke and it pushes me about 16 mph when alone. I don't think I have ever used over 1 1/2 gallons of gas in a long day. It runs like a swiss watch and is quiet. I don't miss two stroke exhaust at all.

Slyster is right on the money, weight is everything on those small boats. We had to go to heavy duty 14s for our 9.9 4-strokes and they're still too heavy. This year we traded in 2 9.9 4-strokes for 8 hp 2-strokes just for that reason.

FYI: I cruise at 21mph (and I a big guy at 220lbs!) and don't have any problem with exhaust... the newer 2 strokes really run smoke free... especially if you run on Amsoil (which I do)... again a bit louder no doubt.. but not so bad!

Also.. I have my deep cell battery inside the rear bench I sit on.. even more advantage to go lite in my case.

Thanks for the replies everyone. I was considering a 4 stroke for the trolling aspect because they'll idle a lot slower but weight is an issue. We (my wife and I) fish a lot of smaller lakes (under 1000 acres) that have some pretty lousy landings so the lighter the better.

One thing I was thinking was if a 4 stroke can troll slow enough to avoid using a trolling motor, wouldn't that make up the weight difference?

With a smaller boat like yours, you'd only need a 36 or less and with the wieght difference between the two and four stroke, you should still be less that with a 2.

In cae this helps.. my 2S 15hp Johnson idles quite slow.. I can go as slow at 1.5mph or so... not sure of the difference in models at slow speeds though.

yeah smaller 2 strokes like my old 15 I had and the 9.9 we have now on our duck boat idle soo slow you cant even tell your moving. I thought they were rather quiet compared to the older motors Ive seen. They troll down very nicely.

Can anyone comment on the difference in maintanence costs between the two? I have never owned a 4 stroke but may soon.

The two stroke you are burning oil, the 4 stroke you have to change it so that should be a wash, I am sure they both have the same lower unit oil change schedule and cost. How about valve adjustment, timing belt, winterizing, etc.....

I don't know on 4 stroke. But I follow directions for my 2 stroke and there's nothing to it! Fog the cylinders for the winter. Put grease into the 3 or 4 grease nipples each year. Ummmm... that's it. Unplug gas line when coming in from a day out.. to run the gas out of the carb etc.. I do this every outing.

Clean gas and oil... always use ethonal free gas however!.. I already had my carb gum up once from 'normal' gas.

Has anyone heard any more news on the outlawing of 2 strokes? I do not know if this would include the private sector or just manufacturing companies. When I buy my next motor, this could be a factor in what I buy.

I think they will outlaw 'older motors' and all 2 strokes today meet the tighter pollution standards. Certainly they can't make people just toss out their $2000-$6000 motors.

I doubt they'd outlaw them. The existing motors would be grandfathered in and the manufacturers would have to go a different route. However, with that said, I highly doubt they'll ever outlaw 2-strokes all together. They'll do it based on emission numbers, which is why you see a lot of direct injected 2 strokes still in production and not a lot of carb'd 2-strokes anymore.

I haven't owned a 2 stroke for 5 years and it was an 82 Evinrude. With my 4 stroke 15 hp it costs a couple bucks for a quart of 4 stroke oil and about 8 bucks for a filter. I don't know how much 2 stroke oil most people use in a season. I didn't like mixing oil and 2 stroke exhaust made my wife get a bad headache. I bought 6 oil filters on ebay a while back for 10 dollars so I am set for years.

An '82 would smoke a lot. My '04 has zero smoke.. really clean. No worse than a 4 stroke for smell I would guess.

      I live north of the metro in East Bethel so not to familiar with south metro lakes. Minnetonka, Prior, Medicine, seem to have some popularity. On the north side the Chisago City area Green, Chisago, Lindstrom, Center, and Comfort are usually productive for pan fish, northern, walleye and summer bass. Big Marine also holds some nice crappie to 14" and larger Sunfish. Forest Lake and a bit west Coon lake also holds a variety. Last year I did a fairly extensive look at DNR lake surveys within a 3 hour drive north of the metro and came up with this list that looked promising for Walleye. I have fished a few during summer, but not all, with fair success.  Here is the list. This is typically what you will find on the DNR Lake Finder site only their survey will be for all species. I just took the walleye info. The Navionics link BringAnExtension listed should give you great contours for any of the lakes your interested in.

      Well that fell apart quickly lol, Looks like starting tuesday we won't see above freezing for a while, I saw lows in the single digits and even a - sign!

      Scored a lowrance Elite 5Hdi today for $169.99 (awesome sale). Plan to use this on ice and in boat for GPS purposes. Paired with the navionics app, excited to compare accuracy side x side.   If interested in the sale, it's at a store that rhymes with meander fountain..     This is an upgrade for me, I have used the app with good success. Hoping this new unit will be a bit more accurate.

      I scored an ice armor extreme black and orange jacket for $140, lots of new jigs with free shirts and hats as incentives. Crowds were insane, easily the largest I have seen in many years of attendance. Had a great time though. Ice is inevitable, but my patience is not my strongest virtue
