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

wow bro 1:29 to 1:33 that's some serious cranking, is it normal to vibrate like that?

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.

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 :)

That boat is SOOO . . . CLEEEAN !!

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

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.

Thanks for posting this!

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

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?

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.

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.

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

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

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

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

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.
