Mercury 3.5hp Speed Test

[@MrSirPhase3]

It's great seeing someone who points their camera at reference points such as the shore or other stationary objects so we can get an accurate idea of how fast the motor is pushing the boat. So many you tube video photographers seem to point their cameras directly down at the motor while at full throttle which gives very little, if any, usable speed information. Thanks for the well filmed video.

I have about 15ft plywood flat skiff and old 8hp 2 stroke outboard which does same performance as yours with 2 person and gear. Although im not sure if our boats compare because mine is Propably heavier. Still im impressed so much of tohatsu that Im thinking getting one. Do you think 600$ is too much for new? Did you tune your carb? I want cheap, economical and new motor so i dont need to row in the middle of the lake.

[@r2bboats]

Yah I’m sure your setup is heavier and with an extra person, you getting similar performance to my boat with a 3.5hp makes sense. If I put your motor on my boat with just me it’d do 10-15mph. Yah Tohatsu makes a great outboard and they make the Mercury’s. At least the Mercury’s under 25hp. I think $600 for a new Tohatsu 3.5hp is a very good deal. A new Mercury 3.5hp is around $1000 at Cabelas/Bass Pro. I haven’t messed with my carburetor at all. I understand wanting the reliability. And a new four stroke Tohatsu would definitely be a reliable motor.

[@Chukartramp]

Short shaft you would know from experience!

[@philipcoleman8184]

I have 2 dinghy’s both around 12 feet. I have a rudder on both but do you find that you can steer ok just using the motor. If so I’ll mount mine central.

[@rainerneumeister5239]

Do you think the modifications made this motor faster. ?

[@crunchwrapsupreme8812]

Seems about right I dual use my 3.5 merc Also a 14 v aluminum And on my 22’ sailboat 2200 lbs pushes my sailboat no problem at 5 kts

[@r2bboats]

I have to say that 3.5 Merc is one of my favorite motors and I’ve had a lot. I’m sure it’s a perfect set up for a sailboat too. Thanks for watching!

[@rainerneumeister5239]

​@@r2bboatsdid you ever test the 2.5 HP mercury. ?

[@LancerNik13]

One of my favorite lakes, looking at a 2.5 vs 3.5 merc for a 11ft inflatable. Todays pricing is $300 difference, which would you go with? Thx

[@trevorlahey1956]

they are the same weight you should go bigger

[@carmineangelino7479]

Scusami potreste indicarmi quale carburatore usa?

[@user-lm3bp6gu5p]

I have a 14ft Lowe aluminum its me and my wife im your weight my wife 140lbs we would travel light with gear small cooler and a couple rods.You think I could get 10mph?I would only be lake fishing.Thanks

[@rainerneumeister5239]

Did you ever test the 2.5 hp mercury.

[@RODNEYSGARDENINGADVENTURES]

How did you keep the front of the boat down my 10ft jon boat lifts the nose like crazy with out anybody in it with me

[@r2bboats]

Hey sorry for the late reply. But the longer the boat the easier it is to keep the bow down because of the leverage. A 10ft is real hard to keep down. But on this run I had another motor I brought with me to test and it was weighing down the front. Thanks for watching!

[@carpecapture2772]

hello are you still satisfied with your mercury 3.5 hp engine?

[@northeastfloridafishin]

how heavy is the boat?

[@r2bboats]

Hey sorry for the late reply. That boat was pretty light. I think it was right around 80-90lbs if I remember right. Thanks for watching!

[@carmineangelino7479]

Scusami ma è modificato? Come fa ad andare così forte?

[@castmastersoutdoors7762]

What is your transom height?

[@bushpig8109]

Does it also start in forward position or is than a gear save engaged?

[@r2bboats]

Hey, I wasn’t able to start it in forward gear. It would only start while in neutral I think as a safety feature.

[@bushpig8109]

@@r2bboats Are you sure about that?

[@r2bboats]

@@bushpig8109 I accidentally tried starting it while still in gear and it didn’t start. I switched it to neutral and it started. The Mercury manual states to place the shifter in neutral before starting. Is it possible for it to be started while in gear? Maybe, but I haven’t tried with the goal of getting it started while in gear. It’s been my understanding that the newer motors don’t start in gear as a safety feature.

[@bushpig8109]

@@r2bboats Thanks, so it you were able to crank it while it was in gear?

[@r2bboats]

@@bushpig8109 I was able to pull the rope but there was a lot more resistance and it made some deep coughs. But the rope definitely wasn’t locked out or anything like that.

[@CdubYahfr]

Can u get it on plane?

[@floridamansgarage8629]

Seems like it’s overreving have you tried a higher pich prop?

[@r2bboats]

I unfortunately don’t have the motor anymore and never did try any other prop pitches. I replaced the stock nylon prop with and aluminum prop but the pitch remained the same.

[@FranksDIY]

I'm thinking of getting a 3.5 for my 12foot aluminum

[@r2bboats]

So far I love the little Merc 3.5. There are a couple lighter options from different brands out there but otherwise it runs great and puts out pretty darn good power.

[@brettkelly4575]

I bought a 2.5hp 2021 mercury amazing engine and the only difference is carb and propeller which I can install for less then the price difference is

[@FranksDIY]

@@brettkelly4575 i bought the 6 hp tohatso and i'm happy so far. thank you for the reply.

[@brettkelly4575]

@@FranksDIY I would gone bigger but it says on the placards 3 hp max even though a 9.9 would fit

[@r2bboats]

I agree the little Mercs are great. And yah the difference between the 2.5 and 3.5 is pretty minimal even without changing anything. I love mine!

[@denizin_oglu]

This motor long or small şaft . Please

[@thefishingmusicians]

he mentions short on the video

[@r2bboats]

Hey thanks for watching! Yep it’s a short shaft

[@videomaker8207]

Goes good for a 3.5 4 stroke

[@r2bboats]

Yah I was super impressed with the power it had. It’s a great little motor.

[@Chillwaving]

Why another outboard in the boat 😂

[@r2bboats]

Haha can’t be too prepared. I was actually just doing two separate speed test videos that day on those motors.

[@veryrudeguy]

So weird... In some videos this thing is barely moving in some like yours its flying.. Some are max speed 6mph your are 9.6mph... ahh upgraded carburator

[@edwardcreel4571]

5 hp carb will actually make it go 1-2 mph slower what a stupid idea needle is to large

[@r2bboats]

🤫

[@OffTheHookFishing]

Why should it make it any slower? Its just putting more gas in the engine right?

[@r2bboats]

@@OffTheHookFishing although I didn’t change the carb myself that’s the general idea and I agree. A lot of these small motors are identical with the only difference being a the carb and some shims which create more horsepower. I too don’t understand how it would make a motor slower.

[@fredknoch]

The bigger the carb the more fuel it puts into the combustion chamber. At some point it’s too much fuel which leads to poor combustion and reduced hp. Imagine putting a big block Holley carb on the 3.5 outboard - it wouldn’t be able to run.

[@bossfishsd3769]

From experience….. the 3.5 is 1 cylinder and the 4 is 2 cylinders……. the 5 hp upgrade really only works on the 4hp motor… Dimensionally the 5hp carb is the same ( however i did not check jet
