Cold Start / How to correctly start the Bayliner 175 3.0 Mercruiser 

Thank you so much... I just bought a 2000 Sea Ray and was having trouble starting it up... My second time taking it out today and took me 15 minutes before I can start up... I'm new to boating...

That boat is SOOO . . . CLEEEAN !!

Thanks for taking the time to post this video. Just got my F17 FLIGHT series this morning. This is info that I need. Thanks from the UK

Always great to see a fellow South Carolinian who posts good videos. I have a 1995 Bayliner Capri 1954, and I start it the same way after it sits for a while.

I do it the sAme way and its works great for me....is nice to see other people doing it the same way :)

Thanks. I really needed to see this. Can’t wait for tomorrow.

I started a 1997 Maxum/Mercruiser that's hardly used using your technique today and voila! Now the fellow who shares the boat won't burn out the starter motor.

Thank you I am going to try that when I get my new boat

I just watched the last 15-20 seconds a few times to make sure I had the muffs on correctly and water was flowing like it should. Funny the little things you get out of videos sometimes :)

I start mine almost the same way, pump 3 times instead of 5 is all. I agree, what is cleaning the carb going to do if there is no gas in the bowl.

i have a 2005 glastron gx205 with a 5.0 tks engine, and this way works perfect,

Nice video. Here is the deal. Crank if for 5 sec and then pump it 3 times. No need to pump it before you get fuel in the carb. If the carb already has fuel it will start before you crank it.

Thanks for posting this!

Great video. I will use this technique next time. Thanks

Most, if carbureted, and recently run, will start with one full throttle pump, and then return to about 30% throttle, then crank. If it has sat for some time, a little carb priming might help. Doing this many pumps with mine would flood it, as I've had the carburetor modified to increase the size of the ports under the accelerator pump, to get rid of hesitation upon acceleration. Fuel injection is a different animal, of course. AND, what works for YOUR boat may not work for every other 120/140/3.0. But, whichever fuel system you have, FIRST: run that blower at least five minutes before cranking, or better yet, lift the engine cover and visually inspect for leaks, and sniff for gasoline before turning anything on. A boat explosion is no fun at all.

I start mine a bit different. As you state, it doesn't help to pump it if the fuel bowl is empty. If you haven't started it in a month, the fuel bowl is most likely empty. Crank for 5 seconds then pump then start.

Thats how i start mine. Works every time and not destroying your motor

I start mine about every month too because if I don't it ends up not idling and bogging down when you rapidly accelerate. Never had any problem until I moved to Palm Springs where it gets super hot. California gas doesn't have a very long shelve either and fuel stabilizer didn't help. I even installed and extra fuel filter and shutoff valve and that helped for one year but it was back to having the carb worked on the next year which had become a yearly necessity. Btw, when starting my Mercruiser 3.0 don't ever have to give it any throttle and it always starts right up. Since I've moved here I have to start all my small engines for my motorcycles, ATV's and generators too or they get gummed up really fast and only after a couple of months. I also siphon the gas (always make sure I don't bring it back with more than a 1/4 tank) and put in fresh 3 or 4 gallons.

I always try turn over first nothing then I pump it. I have had them start first try and others I had to open butterfly open to start for the season.. crazy

I installed a manual fuel pump, the kind you find on small outboard engines, and all I do is pump it a few times untill I feel some resistance in pumping and then the motor starts first or second time I try. The previous owner used to spray wd40 in the carb and had a real hard time starting the motor.

I have the same boat and your videos have been extremely helpful! I’m having issues with the gauges not reading at all. Switches and everything else work great! Would you have any ideas or recommendations to troubleshoot? Fuses are all good and engine runs great!

I never pump mine at all, crank it for a few seconds, back to off, crank it again and it starts.

thanks!!

My mechanic just show me this way yesterday and what are the odds, I get this video recommended 🤭

thanks I'm new and that's a goooood help for me

I have a 18 foot crownline that 190 horse power engine it has sounds amazing it down shifts and up shifts amazing

Do you recommend doing anything extra before trying to start a mercruiser 3.0 that has been winterized?

Tip. My boat mechanic showed me the secret Open hood, and listen, when you push the throttle forward leave there and listen you will hear it spray fuel Pull back to neutral shove ahead again wait and it will do it again Works every time Bayliner 185BR

Thank you

Thanks for the video. Have you made a video best place to mount a transom transponder for a fish finder? I’ll

good morning, I just bought a bayliner capri 1998. thanks to your video i was able to start it up. my first language is not English and have some hard time understanding boat terminology. at this moment the boat 1. starts but accordingly to the previous owner it needs a new CDI box because you need to push the level forward to keep it going 2. got home and tried starting and the throttle bbutton got stuck in. whats this mean to the operation of the boat?

I got a twin shift/throttle..should i be pumping the throttle or shifting from F to N in my case?

Great video. This is my 10th season of my 2006 BL 175, and over the course of those many years, I have developed a very similar methodology for cold (more like hasn't been run in several weeks) cranks. It just gave me hell in particular trying to start it on a cold evening yesterday on a cold October day in Pittsburgh, PA. Had to do this about 3 times with time in between to prevent flooding when the first 2 tries didn't turn. Man, your boat is spotless, what year?

New Subscriber! Thanks for the video. I have a 2008 Bayliner 185. Same engine, I think. Mike

I do the same thing on my 2003 Bayliner 192 with 3.0 Mercruiser which I just bought recently. Is this the typical startup on Mercruiser engines or Bayliner boats? Thanks for this video

You need to give it a min or two with key on, engine off to let the choke open up.

Hi great video just wondering is this how you turn on models from 2022 also?

What does the blower do? I just bought this boat yesterday and i love it but had some starting issues

I have a question, I have a 2001 mercruiser 3.0 and after I run it for 3 or 4 hrs pulling skiers and etc. it doesn’t want to idle low and if it goes dead it’s a pain to get cranked back up if it does! But usually cranks right up in a cold start just gives me issues when I’ve been running it for hrs?? Any suggestions would be helpful Thanks

I will believe everything you say just because Your boat is SOOOO F'i;ijefw;oij CLEAN!!!!! Yes sir I will do whatever you say I should do sir. Pump it 5 times? will do sir!

What makes the dash lights come on?

How often do you have to change your starter?

Hello sir, thank you for your informative videos, so I wanted to see if you can help me out. I have a sea ray 185 bow rider with a mercruiser 3.0 alpha 1. Do you have any input as to why trim up/ down was working perfectly fine , next day I went to check it before leaving to ramp and it is completely dead,. It acts like there is no power to it. Thank you in advance for your time.

You can go under the dash and put a piece of electrical tape on the ignition alarm. It really knocks down that high pitch hellish noise I don't want to hear when I'm on the water.

Hello I need to replace my hub bearings. I have the exact same boat and trailer. Can you tell me the size of bearings I need? If you have replaced them before.

Is it the same for warm startup?

What is the alarm bell that goes off when you turn on the ignition

Do the trim have to be down?

Once the engine is up to temp how is the starting then? Say after a hot soak on a busy cruising or tow day?

I'm thinking about adding a primer. Just hook a switch to th electric pump to fill the float bowl.

you forgot to say" Turn on the battery first"

what is the purpose of turning on the blower first and then do you turn if off once the motor is running?

Do you use non ethanol gas?

Can you explain, what is that cable you have below the throttle lever? what is the purpose of its use?

Can you show Us, how connect de water to the engine? please.

2 pumps mine fires right up

Is there a choke?

I agree with most of your video, but why did you pump it first five times. After month or two carburators are probably dry, so just like you said, "If you don't have any fuel in a carburetor, ..."

Do you know why the boat has long beat after you first time you couldn't start up the engine. Mine has the same sounds(long beat), but it's after the engine was on about 20 second. Any one has an idea about it?

spray some marvel mystery oil into.the caburators

open the throttle off idle and she will start a little easier

TKS I just flip the key and it starts right up...

That's waaaay to hard to start. My mercruiser 5.7 starts cold with less than 2 seconds of cranking. No pumping necessary.

You have a similar boat to mine but mine only clicks

LOL omg this is funny... i seriously thought pumping the throttle before start was some goofy shit only my old struggling boat requires because i figured it sets the choke position, and primes fuel into carb. i really thought it was just my own trick technique i figured out LOL... new to boats, new to old carbs, not new to mechanics atleast

Thank you for this video. This is accordance to manual as well. Only 1/4 throttle - some cool youtubers start with 3/4 or 4/4 throttle just to show off. Will the engine stink some gasoline however when you do this starting procedure?

My Mercruiser starts on the key without any pumping. Just crank it fir three seconds and fires into life

Is this boat any good for fishing?

That is why you fail to start from the first try: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-brufYuYGxfI.html You should keep key on ready to start position for 2 minutes

I think something with your carburetor settings or fuel/air mixture is wrong. This motor shouldn‘t start up so hard. I had an old 3.0 without TKS built 1994. Startet up perfectly with only pumping 2-3 times and 1/4 throttle even when not used for a longer time. On daily use on vacation, 1 pump and little throttle was enough for cold start. In my current boat i have a 5.0 carburetor. Cold starts without pumping at all, little to no throttle depending on outside temperature

How to correctly start a Bayliner 175: 1. Make sure key is in your pocket 2. Trailer boat to nearby marina 3. Trade in for a real boat with EFI I kid, I kid. The newer Bayliners actually look fairly decent!

Defeats the purpose of TKS (turn key start); not pump 5x-crank-pump 3 more times-start. You need to clean the carb.

Everything is right except , you run the engine first before the water ....

You pumped it too much the second time

Pumping it 7 times, is not right. It shouldn’t take that much. My same engine starts right up at two pumps or less. Sorry. 🇨🇦🤷🏻‍♂️

First, you run the blower for 4 or 5 minutes before the water or starting not just a few seconds. I realize that would make for a long boring video but you at least have to say it. Second, you don't run the water without the engine running just as you don't run the engine without the water running. Both should start at the same time - within a few seconds of each other - the same time is preferred. Third, if it doesn't start in the straight up and down position within a few seconds of cranking you have a problem that should be looked into. That's why it's called turnkey. Back and forth 20 times? You shouldn't have to do it once. And you shut off both the water and engine at the same time - within a few seconds of each other

Start it and drive it into the bay liner junk pile
