  • In this video I compare a Mercury 3.5hp four stroke to a Mercury 3.3hp two stroke.
    I found it very interesting and some of the results where surprising.
    The four stroke weighs about 6kgs more than the two stroke which is a fair bit when the two stroke is only 12.5kgs.
    As both these motors are used widely and abundantly as tender or dinghy motors, I thought this comparison video may be helpful to some.
    Cheers.

    Great video, short and to the point with no extra stuff to skip through! Gotta love the sound of the 2-stroke when you hit the gas lol. The 4 stroke just sounds weak and struggling and the 2 stroke just sounds happy to be on the water

      As somone who had a 2 stroke 5hp motor
      And now a 4 stroke 6hp
      This is verry true t strole sounds amazing
      But for me the bigest difrence is
      The 4 stroke runs and the 2 stroke well wont anymore and i dont know why

    I have the 3.3, thats my baby and I keep it covered and wax the cover after use so it still looks new. I got it in 1999 new, clean the carb 1x per year with new spark plug added, water pump every 3 yrs. last year I had to buy a new cdi for it but other than that it has been super reliable

    Top video, mate. Very interesting. Also, loved the video on the workings of a two-stroke engine. Informative indeed. Even for a complete novice like myself.
    I’m currently tossing up between getting a 4/5hp 4-stroke or a 4/5hp 2-stroke outboard.
    I’m going to put the chosen motor (based on the decision made) on the transom of a kayak/boat called, Jonny Bass Boat 100. I think it’s a planing hull, but not certain as I’ve also heard someone say it’s a displacement hull.
    The hull on these ‘boats’ leaks water thru the pod, when outboards above 2.5hp are attached, which is why many people who attach higher horsepower motors to it end up fibreglassing the hull. Something I will do too.
    I’m just curious on which outboard 4/5hp (2 or 4-stroke) you’d recommend for the Jonny Boat 100?
    After watching your videos, your opinion and recommendations would mean a lot to my near-future decision…
    Kind regards,
    Dimitri

    I purchased a used Sears Gamefisher 3.0 HP 2 stroke, air cooled, aluminum prop boat motor back in the mid 1990's at a yard sale and it ran perfect. Here it is over two and a half decades later and i'm still using that same great running boat motor. I just purchased another one that the seller dropped in the water while it was running. When I got it home the piston was seized up. Took me a day to get it freed up and now it runs just fine.I sold my aluminum 12 foot boat and purchased a 10' Pelican Bass Raider pontoon boat which is where this motor will be attached too for many more years to come. I prefer two strokes for the reasons you mentioned. They are lighter, Stronger running, and mine is air cooled so there's no impeller to replace. Tanaka sold out years ago so this motor isn't made any longer but running and/or parts motors are still available on facebook marketplace, craigslist, and ebay. I'm always searching for good deals on this 3 hp engine, running or not.

I seen lot of 2.5 HP 3.5 HP engines are these outboard any good for my little boat? Thanks in advance

    • @25hpboatracerman
      @25hpboatracerman  Před 2 lety

      Hey mate,
      A 3.5hp will push it but it’s not enough if you are going against a head wind or something.
      Normally a 5.35m boat will be a long shaft transom too so check that before you buy a short shaft because a short shaft won’t work.
      A 25hp sounds better on a boat that big, you may get frustrated going 4kph with a 3.5hp and full throttle everywhere.
      Hope this helps.
      Cheers 🍻

  • @johnb9825
    @johnb9825 Před 2 lety

    Cool Video. I want to bring up the possibility / probability that the balance of your boat may have impacted the speed test. When the four stroke is running, there is considerably more weight aft of the boats CG. Then when you move the four stroke up front and put the two stroke on the back there must be a balance difference right? The drive-by comparison you did at the end of the video says it all... Just look at the difference in angles of attack as you go by.. Much more level with 3.3 2S and very steep with the 4S. THAT definitely makes a difference in speed efficiency.. A level boat goes faster. Try doing a test where the CG angles (weight distribution) is the same. All that said, Wow, that little 3.3 surely held it's own.

    • @25hpboatracerman
      @25hpboatracerman  Před 2 lety +1

      Hey mate, good thoughts for sure and definitely would have a small impact, not as much as thought though, I did try moving my body further forward with the 4 stroke on the back with no improvement.
      The weight difference is only 6kgs, like moving my leg forward a bit in the boat. In saying that I’m sure there is a small impact from the 6kg difference in weight being placed in a different spot. I only put the spare motor on the middle section, not right up front. I do feel like the boat was more bow up with the 4 stroke because it was less powerful and slower, the two stroke seemed to push passed that point and nearly planed, leveling the boat because of more speed.
      Cheers for the thoughts, that’s what it’s all about 👌

    Did you have the 4 stroke at its lowest trim? It was certainly riding a lot less level… which will be partly based on weight, of course, but will greatly impact speed. No surprises here… thanks for the video. The real market segment impacted by the new regulations is in the 15hp size, in my opinion. You simply cannot get a portable 15hp 4-stroke that is light enough. It’s a more expensive comparison to organise though… collaborative effort might make it more viable?

      The trim settings where set to optimum for top speed on both motors.
      The 4 stroke just is definitely less powerful.

      If you are after a light hood two stroke motor the 9.8hp Tohatsu is amazing for only 26kgs. when you go to the 9.9hp Tohatsu it’s a much bigger capacity so lots more torque too which is nice.

      True but the 4 stroke is bigger, Heavier noticeably not as fast and more complex and you will have to change the oil twice a year. But you can troll for as long as you want in the 4 stroke and you wont foul your plugs like in a 2 stroke.

    The 2 stroke also has what sounds like a higher rpm. If using the same prop this can only equate to a higher end knots.

      Hi Mate,
      Yeah I was surprised at the difference.
      I wanted a fair comparison, both has props on that are supplied from factory, both the same pitch, both the gear cases are identical and with the same gear ratio, the 4 stroke just not as powerful. the rev range on the 4 stroke is lower for max recommended rpm too.

    For someone using the motor as a main drive motor, I would prefer the 4-stroke.
    But I'm looking for a kicker motor for trolling with on my 14' v-hull. The set throttle on the two stroke would make trolling far easier. Neither motor pushes fast enough at idle like I would hope for.

      I think I'd stick with 4 for kicker. Also nice some 4 are so quiet makes it more pleasant. 2 stokes tend to foul plugs if you run low rpm a lot. Although I troll often with my Johnson 25. Gotta wring it out occasionally and keep a wire brush and spare plugs on board

  • @nerd1000ify
    @nerd1000ify Před 2 lety

    I think a big part of the reason for the speed difference is the heavier weight of the 4 stroke. When you motored past the camera side- on the boat was clearly much better trimmed with the 3.3 on the transom, meanwhile with the 3.5 the stern was buried quite badly. Might be interesting to move your weight further forward (e.g. with a bit of poly pipe as a tiller extension) and see if the 4 stroke gets closer to the 2 stroke's speed.

    • @25hpboatracerman
      @25hpboatracerman  Před 2 lety +3

      Hey mate,
      Looks that way for sure but the 3.5hp 4 stroke definitely has less power which is part of the reason for the boat sitting lower at full speed. The two stroke seems to just push past that stern down plowing stage.
      In reality the weight difference is only 6kgs so it’s not a massive amount that will affect things too much, like moving a my leg forward a foot or something.
      On board the 3.3hp two stroke defiantly feels like it’s got another 0.5hp over the 4 stroke.
      I do like the tiller on the four stroke though, way better.
      Cheers 🍻

      @@25hpboatracerman It's interesting that two nominally similarly powered engines have such a difference, particularly in the 'pick up' when you open the throttle. Clearly the 2T has more low end torque, and probably also a lighter flywheel.
      I have the 3.3 2 stroke on my Caper Cat. Flat out it pushes us at about 7 knots, but it is very thirsty for such a little motor, especially at full speed. I also dislike the pollution it emits, the constant misfires at trolling speed, and the way the leg drags in the water when we're sailing because it only lifts about 45 degrees. So I'm contemplating a 4 stroke replacement. Any advice?

      Hi mate,
      Yeah, the two stroke do use a bit of fuel hey. I get about 4 to 5km from the onboard tank on that dinghy in the video.
      The rough idle is because they are such a simple motor with fixed timing, they also sometimes have a bit of a flat spot from idle to speed because of that fixed timing too.
      The 4 stroke I tested has the exact same leg, clamp bracket and lower unit as the 2 stroke so it will only trim up the same hight with the same retainer push pin.
      I didn’t have the 4 stroke long enough to see how it was on fuel unfortunately. The 4 stroke would definitely have less pollution.
      The two I tested are actually built by Tohatsu (Mercury just put their stickers on) both good little motors.
      I feel your pain with the leg dragging, that’s not ideal, I wonder if there is a mod that can be done to gain a bit more trim when not using, a wedge or something?

    Two strokes fire twice as often a 4 stroke . That’s why they have more power & torque , the down side is they use a lot more fuel & they consume oil for the life of the engine. However power to weight they are just so hard to beat.
    Poor old 2 stroke marine engines are very handicapped compared with their higher power brethren two strokes. The exhaust expansion chambers of motorcycles are the heart of the famous two stroke power band , a high power designed engine of the same cc displacement would likely achieve 7- 12 hp .
