I want to replace my 15hp gamefisher 2-stroke with a new 4-stroke model. The boat is rated for 15hp (14' john). I like the Honda 20hp. I want to know what you all think about differences in brands at this horsepower, and if the boat can handle a little extra hp?

Re: New 15-25 hp outboard. Brand?

The boat ought to have a plate saying what it is rated for. You need to follow it. 20 would probably be close to a maximum. Keep in mind that 4 strokes are heavier that two strokes. If you are going to take it off of the boat you need to know that 4 strokes are also fussy about which being layed on their side<br /><br />As far as brand, there really isn't a bad one you can buy nowadays. I think that I have read here that Hondas need to have their valves adjusted fairly regularly especially when new

If you normally carry your engine seperate from the boat, you may not be doing that with a four-stroke. Those seem to be just beyond my personal limit in that HP range. (+100 lbs).

I could probably manage the weight, but I am concerned about not being able to lay it down. Is there a "correct side" or just upright transport?

for a fourstroke, upright transport is necessary. for a 2-stokr, it really normally doesnt matter.

A lot of the four-strokes have a particular side you can lay them down on. But they also must be carried upright rather than how you normally carry one by the handle. It's something you should definitely be looking in to.<br />I'm no wuss myself, it's just the awkwardness of carrying the thing that makes the weight bad. I can hardly go ten steps with the 140lbs of my 28hp. As comparison, your Gamefisher comes in at around 65 lbs.<br /><br />EDIT: Looks like the Honda has a normal carrying handle. The (online) owners manual doesn't seem to be clear on if you can transport it like that.

All four-stroke portable engines are designed to be laid down on one side. They are also designed to be carried by the handle...When you carry it by the handle the engine lowerunit is hanging down and the oil will stay where it is supposed to. Some can be left on their back, but it is better to lay them down.

I normally only remove the 15 I have now on long trips. The boat pulls a lot better and bounces less. If I leave it on, will the bouncing cause damage over time? Also, what about transom savers, would that take care of the problem?

It can cause damage...but it shouldn't. The bouncing effect of the engine, in the tilted position, can stress the transom and the engine mounting system. A "transom saver", hence the name, would help.

Transom saver on a small motor without power trim may be a bit tricky. You need some force to hold the motor against the saver which takes the weight of bumps off of the transom. I am sure something could be rigged to solve for this. You might also look at adjusting the trailer a bit. Sounds like you could move the boat forward and balance the load better. Moving the weight closer to the axel can really help solve the bouncies.<br /><br />The Honda 20 and 15 are the same weight and they are just over 100 lbs. I agree that you should not go over what your boat is rated for. Not so much because 5 HP is dangerous, but think about what an insurance adjuster might do if you had a claim and you were over the max rated HP.

Re: New 15-25 hp outboard. Brand?

The reason that I have began thinking about this whole 4-stroke upgrade was that I wanted to be able to take bigger risks, farther into the back country, than I was willing to take with the motor I have now, but all of the maintenance seems daunting. Should I be looking at a newer 15 2-stroke for ease of care, weight, etc? Also, is there much difference in new small 2-srokes, like all of the advances in the larger models?

Mays:<br /><br />I love the new motors (I have an e-tec) but you sure can't beat the simplicity of the old carbed 2 strokes. I had a 15 Evinrude for years and it was an excellent engine. If you go that route, just make sure you have spare plugs if you're going into the back country. <br /><br />Good luck.<br /><br />You can still get a Johnson or Yamaha but Merc is going to (or already has) discontinue making the 2 strokes.

The 15hp Yamaha two cycle is a excellant motor. We run them commercially and have had no problems with them. They are also very light and easy to work on should you need to.<br />Go two stroke IMO.

Mays,<br />Re: your transom saver question - I use one on my Honda 15 (Swivl-Ez from Cabella's.) It uses a rubber tie-down to hold the lower unit snug to the device so it doesn't bounce off. Works fine.

If you are looking for reliablity in a new motor. I would not assume that a brand new 4 stroke will be more reliable than a brand new two stroke. My opinion is that the 15 Johnson is pretty rock solid and I would have no fear of taking it deep in the back country. In fact I take several trips a year where I go up one lake 6 miles to a truck portage, then go to a lake on the US/Canada border. This is a 30,000 acre lake and if you run into problems you can be there awhile before you find some help. Cell phones don't work either. You more or less have to wait for help, or hope someone stumbles by. There are a few outfitters that rent boats and provide guides. Reliability and performance are both at a premium because motors are restricted to 25 HP. Here is what I see a lot of up there:<br /><br />1. Lots of Suzuki DT25 Two Stokes (no longer made, and clearly the best performing 25 I have seen)<br />2. Merc 25 Classics (can be fiesty on the troll, but solid on cruise and WOT)<br />3. Johnson 25 two strokes (reliable, but performance is not great compared to other 25s)<br />4. Honda 25s ( seems to be the prefered 4 stroke, and one reason is the weight)<br />5. Yamaha 25 4 strokes. Also light, but two cylinders instead of 3. Slight edge to Honda on performance.<br /><br />On smaller boats, the johnson 15 is most prevelent, but there are a fair number of merc 15 classics as well. 15 four srokes are seen from time to time, but not nearly as much as 4 stroke 25s. <br /><br />I just bought a new boat and went with the Honda 25. So far I like it because it is reasonably light, reliable, quite, trolls nice and economical on fuel. It does not match the suzuki 2 stroke in performance, but it will hang right with the merc 25 and ease away from the johnson 25. Most of the boats are Lund and Alumicraft.<br /><br />Last trip up was a couple weeks ago. We took my friends 1957 14' Crestliner shallow v with a 92 johnson 15. We replaced the benches this winter and the motor is in tip top shape. I think that old stuff can be extremely reliable as long as it is kept in good repair. I would not purchase a used motor and run out to the sticks without running it quite awhile to make sure I trust it.<br /><br />Good luck whichever way you go. Hard to buy a bad motor these days.

Re: New 15-25 hp outboard. Brand?

How about the noise difference? I was kind of thinking 4 stroke so not to scare off all the wildlife. Has anyone got experience with both, that would comment on the kind of noise I can expect from a new 2 stroke? The one I have now is a real screamer at some rpm's and I wonder if it has gotten louder over time. PS the gamefisher I have now has the exhaust port under the anti cavitation plate. I assume that adds to the noise compared to a through the prop model.
