Two Stroke for the win!🥇

[@MurphsFiberglassing]

Got a few of those too.

[@inteligentvtec]

Four stroke outboards can run all day at full throttle. My f90 Yamaha has hundreds of hours at 5,800 rpm. And my little tohatsu 20 is either idling or wide open at 6,000.

[@ChiefCabioch]

@@inteligentvtec does the boat have a tach?...yellow, red line?

[@inteligentvtec]

@ Yes, both boats have tachs. The Yamaha 90 will run up to 6100 rpm with no weight in the boat, but have never hit the rev limiter. The Tohatsu 20 has a rev limiter at 6150 which I'm running into all the time depending on what prop I'm running.

[@alexgoldstein7997]

Thanks. It was my LU that blew up. Working on it. Be ready for Spring.

[@eddiemoser8829]

Some people post ignorant responses to this video who know nothing about high performance boats and motors. So they just post what they think they know. Those are small hub big ear high pitch props and are light weight made to allow the motor to spin higher rpms and allow the 1000lb boat to first of all get way up out of the water which is quite normal for low water pick up lower units to still flow enough water through the motor and at the same time expose some of the diameter of the big ear props out of the water which is normal for those types of setups. Now... To dogmaticlly say what made the motor quit... idk. I wasn't there and I didn't troubleshoot as to why it happened. I have a four stroke 150 on a 18ft bass boat with no upgrades other than a raked prop that gets my boat out of the water enough to put me at 57 mph by myself with a full tank of gas at 5800 rpms. In the past I had a 96 Gambler 209 guide edition which was set up similar to the boats in this video. It had a 2stroke 225 with ceramic intake reeds and went around 75mph at 6000rpms. It was fun but cost alot to operate and fish local tournaments too. So I decided to go to a more standard type bass boat with a four stroke. I love it. It sips the gas and more reliable and affordable.

[@MurphsFiberglassing]

Thanks for the reply. Agree most don't understand the running of high pitch performance propellers. Propellers are your boats transmission, one which you dial in with the propeller to the motors setup and performance. In my case it's the lower unit that has failed not my engine. I have added an Update link in the description.

30" A5 Mercury Chopper

[@CZDigger]

I remember when the Mercury Optimax became known as the Poptimax😂😂😂😂. My dad was a huge merc guy until one day a merc out of the box was bad. He bought a Yamaha and never looked back.

[@MurphsFiberglassing]

Same here with GM until I got lemon and no one gave a crap.

[@CZDigger]

@ same. Dealer said you stuck with it and Mercury said whatever the dealer said Never again. One of pops Yamahas was a 60 enduro. Ran it on a rosborough 18 when they made them. But the engine had a gallon gas tank inside the cowling and once started, it ran on kerosene. Kerosene was much cheaper than gas at the time. May still be, not sure. Yamaha never brought that motor to the USA. Great motor.

[@MikeYurbasovich]

My dad worked at mercury in the 1980's. He said that at the end, they brought in teams of yamaha engineers from Japan to go through their entire product line and manufacturing process before he was laid off. So, there are things in play that maybe led to this problem with quality. They also moved a lot of manufacturing from Wisconsin to Oklahoma. Not sure about the culture in Oklahoma, but in Wisconsin it's roots are German.

[@WhiteoutSnowy]

Did mercury covered the costs under warranty ?

[@MurphsFiberglassing]

I modified the lower unit with a Bob's low water pickup so I'm sh@t out of luck.

@@MurphsFiberglassing Right !

[@joedurso5192]

Looked like you hit something

[@MurphsFiberglassing]

That's what I thought at first. Turns out to be the Lower unit bearing. Must of loss oil somehow.

[@DCFloridasport]

Made sure I commented before watching lol My first guess would be: Looks like a rod broke or bent and jammed without leaving the block otherwise youd have oil everywhere in the water and smoke, that was a big shake😳

[@MurphsFiberglassing]

Next vid shows it was the lower unit that jammed up. Good think I was going slow.

[@DCFloridasport]

@ wow that was a violent shake! Ive seen motors throw rods and it looks just like that and the oil galley usually gets compromised and oil just pours into the water. Ill have to check the next video now lol tight lines!

[@MurphsFiberglassing]

@@DCFloridasport I think it might have to do with the new motor mounts on these 4strokes. They sure bounce around a lot. That might of been a good thing.

[@DCFloridasport]

@ youre right there...its easy when you have twins because the steering stabilizers help a lot, Ive found that a lot of poorly bled hydraulic steering systems that once bled thoroughly it tightened up the movement quite a bit.

[@brianburkhardt771]

I had a 2017 115 horse. For a new motor it ran rough sometimes, coldblooded. Hesitated. It is gone, it was on a tracker pro xs, loved the boat, motor not so much. That is why I sold the boat.

[@MurphsFiberglassing]

Newer generations of the 115 are much better.

[@eddiemoser8829]

@brianburkhardt771 Mine is a 2013 mercury 4 stroke. I have had it 2 yrs has been a great motor. I called the prop Depot in Tennessee and told them what I had and the sent me a new prop they worked their magic on. I put it on $900 later and was more than I expected. Before the boat ran to flat trimmed up properly and couldnt get anymore than about 5400 rpms at about 51 moh, and now the bow comes way up at 5800 rpms and 57mph. Huge improvement.

[@brianburkhardt771]

@eddiemoser8829 I had a stainless prop on it, fast boat mine would run 61 mph on a good flat no wind day. I owned a 2006 tracker with a 50 Merc on it. That was a good motor wish I would have kept it hat boat. That 115 was a runner. Just ran rough on low idle sometimes, it would cut out running half throttle. Just did not like it. She Gone!! I bought a cayak lol.

[@CajunKracka]

You're swinging that motor at 6050 rpm correct? Have you had some work done to it to be able to turn it that high? My 75 merc is rated at 5250. I can swing it at 6200 but i don't go over 5800. Im just curious to know if these 4 strokes can handle that over long term. Your thoughts?

[@MurphsFiberglassing]

Red line is 6300 for this model. It's just purring along.

[@CajunKracka]

​@@MurphsFiberglassing ah ok. Did you ever get an answer on this one grenading on you?

[@MurphsFiberglassing]

@@CajunKracka I have another vid "Motor Carnage Update". It was the lower unit locked up solid.

[@CajunKracka]

​@MurphsFiberglassing that is better than blowing the block. Good luck with it. She moves along great.

[@OhMySack]

If you can roll at 6200 WOT and the optimum WOT is 5200, you need to reprop it. It's well under propped. At the minimum, research the proper mount height, trim angles, prop pitch. If your swinging that much more over design WOT limits, you're gonna grenade that thing or, at minimum, greatly reduce motor life. If money or long term reliability is of no concern, then carry on.

A lot of comments, but none of this makes sense. I think he’s actually trying to blow a motor just to prove a point. As a bass fisherman not sponsored by mercury. Those are the best motors out here. He probably works for Yamaha. And yes, and yes, all my personal boats have mercury’s and look at the motor itself. How old is this motor and how much maintenance has been done on this old motor? They can say whatever they want. We’ll never know the truth.

[@MurphsFiberglassing]

Always been a Merc Man. Lov this engine, it's a beast of a 115. Running 78mph @ 6100rpm, red line is 6300. 2021 with 130hrs. Only maintenance so far is to change the engine and lower unit oil. It was my LU that gave jammed up from the performance prop. Going to have to beef it up. Update kzbin.info/www/bejne/hYbdnnyheMetgtU

Geez ... what a expensive and painful hobby just to go fast on the water and more dangerous than a motorcycle ... I had a few speed boats in my day and what a overrated experience and money pit to just go sorta fast with bad control ... its all good till you hit a boat wake wrong and the whole thing is out of control ... Pass .... if you want to feel speed and power ... ride a motorcycle ...

[@MurphsFiberglassing]

Had a ride on a bike once. Always got my thrill from water. Been in the drink a couple times. So much better then landing on pavement and metal I think. No speed limits on water except in designated areas. Cuts down on speeding tickets. I would rather get my trills in the Sun going fast in a bathing suit and life jacket instead of leather suits on hot pavement. We boat in groups and hit the beaches and restaurants, it's a blast. Easy to pop out for a 3-4 hour run and do 100-150miles of boating. We have lots of water ways in Ontario, Canada. Where I live, endless boating opportunities, short distance from my home.
