I'm glad I found your channel (actually you found mine, then I checked yours out).... Thank you for these great videos; you are a major help to this old dude who is learning how to work on these new high-tech outboards. For the past 35+ years I had diesels, and learned how to do ALL the work on them; even took diesel mechanic classes. With the help from your videos, I'll be able to do all the work on my Yamaha 300.... Great job!

Can you do a lower unit oil pump change out for the F250 Yamaha? Love your videos!

[@ELANSURF]

(Great video!) Questions - What year is this 300? (Ours is a 2015, we just bought...) Also, was that a water pump change? I heard you mention the water pump housing. It appeared to be the top of a housing - I'm not sure if I missed something about a change of the pump. Thank you for providing education for all of us DIYs!

[@ITUMBLE4U]

Thanks for sharing your knowledge and expertise. Any chance you could show how to remove/replace the shift shaft seal assembly on that model? Is it just a matter of prying it out with those two plastic slots or is there some sort of a puller? I haven't found any videos on that. Thanks again.

[@FishOnForte]

Great video. The narration is excellent!

[@BornAgainBoating]

Hey, thank you! It takes a lot longer to edit the video, but I kind of have to because there is always a forklift running. So, nobody would be able to hear anything if it wasn't done that way. Thank you for commenting, you been out fishing? Haven't seen a video for a couple of weeks!

[@andrewfyakim525]

Hi BAB, Thank you! You just recently sent me the link to this. I don't know how I missed it before. I'll now be able to check and change my plugs and thermostats myself... I still don't understand all the 'internal' engine zincs, where they are, and how to change them... On my past two diesel engines the pencil-zincs were on/in the heat exchangers; very easy to replace, and I did so twice a year... How often do you find bad zincs on the 300 Yamaha; how many average hours on the engine; 90 % of my boating is in brackish water, and I flush the engine for 20+ minutes every time I use it... I now have 990 hours, and I have not changed those 'internal' zincs...

[@BornAgainBoating]

There are a couple of internal anodes, but you shouldn't have to mess with those for awhile, and you have to remove a few different parts to get to them, like the thermostat housings and water jackets, etc. The anodes you should change, and at about 1,000 hours, you are probably due. Are the ones that are in between the spark plugs. They are on each head, they are really similar to the ones on the F250, kzbin.info/www/bejne/ZqO4do1sd72rsMk

[@BornAgainBoating]

Hahah Thank you! That's a hard subject to tackle, both of them have good engines and bad engines, it really breaks down to years and types of engines, as well as the horsepower. :)

Great videos! Thanks to videos like yours and others on KZbin, I’ve been able to do most of the maintenance on our Yamaha 4.2L F250 XCA’s. Could you post a video on how to change internal anodes on the 4.2L’s? That’s the one routine maintenance thing I haven’t figured out.

[@BornAgainBoating]

I'll see what I can come up with on the anodes

[@nacholibre747]

Does the water pump shaft turn clockwise for both counter and normal engine configurations?

[@milkylicker6963]

You should replace filter o ring

[@johnethell436]

what type of oil filter wrench do you use and brand?

[@fishydubsfishing6516]

What I don't understand is you got the labor involved to pull the plugs the spark plugs out why not put new plugs in I had an io boat one time and it blew the porcelain right out of the plug because I didn't change them out

[@BornAgainBoating]

At 100 HR's it's just for inspection, you should be getting 300 HR's on the plugs, but a good visual lets you see how the engine is running :) I wonder what it was that made the porcelain blow out of the plug on your IO though, or they were just in there for a very long time lol

[@fishydubsfishing6516]

@@BornAgainBoating I think they were in the boat when I bought it the metal is rolled to hold the porcelain on the outside of the plug there was a ring of rust on the metal and I believe the compression shot the porcelain core out of the plug

[@jamesdeal4709]

Really enjoying all of the content on your channel? Why do you grease the threads on the fuel/water separator bowls. Never seen that before or heard anyone recommend doing that and never had an issue getting them off. I use Parker/Racor filters, if that makes a difference. Thanks!

[@BornAgainBoating]

Thank you! We do that mainly because it makes it easier to get the bowls off and it's usually us doing it :) You get a good amount of vacuum in the fuel system, so over time, they can get pretty difficult to take off. A little bit of grease makes that easier! Racors are extremely common, it's probably preference, if it makes the job just a little bit easier, I'm in! If you haven't had any trouble with yours, you don't necessarily need to change anything :) If it's not broke don't fix it kind of deal there lol

[@jamesdeal4709]

Thanks for the reply! After watching the video I actually read the instructions printed on the filters I use. It says to lube the o-ring on the bowls. Never payed attention before, just did it how I was showed long ago. I'll be lubing the threads from now on,

[@kosta8665]

Nice video, best regards from Ukraine

[@BornAgainBoating]

Thank you!

[@oddsix4311]

What is the blue grease you are using on the bolts and the gaskets? Again a great video!

[@BornAgainBoating]

Thank you! That is Johnson Evinrude Marine Grease, it comes in a tube and works pretty good!

[@TexasFilipino]

So in that triple configuration how is the rotation set up since two would have to have same rotation. Is the outside ones set same and middle one counter rotation?

[@BornAgainBoating]

Close, it's basically the same as with two. Port and starboard are still the same and the center is just another standard rotation. Some people like to swap the port and starboard and put the counter on the starboard side. But that's pretty rare and depends on how the boat performs. For quads it just adds another counter on the port side lol

[@TexasFilipino]

@@BornAgainBoating thanks for the reply. We are heading to Texas and I will hit you up on a few things before returning to the Philippines.

[@BornAgainBoating]

@@TexasFilipino no worries! Thank you for commenting! Ask us anything and well do our best to help you out :)

[@TPSTool]

Do you find better success using marine grease, or actual anti seize on the bolts and spark plugs?

[@BornAgainBoating]

Um, anti seize only on the plugs and then just regular marine grease for everything else.

[@r8drvr819]

What weight Yamaha oil should I use in Southwest Florida 20W40 or 10W30??

[@luderickwong]

May i ask a out of focus question? When i have my boat licence long time ago, the lecturer mentioned that for a boat have twin engine, the best way os to run one clockwise while the other anti clockwise. Does that still apply to modern outboards? If that is the case, what is the direction of the middle outboard in a triple set up?

[@BornAgainBoating]

Yup! You've got a counter clockwise on the port side and a standard rotation on the starboard. On trips the center engine is another standard, on quads it goes counter counter standard standard. You could flip them as well. Common in fountain boats where they do standard standard counter:)

[@luderickwong]

@@BornAgainBoating thanks for the info 👍

[@nowsath5570]

Hye sir,can you post me Mercury 300 & 350 . Shift actuator

[@hashemmatter5389]

Wouldnt you just do the oil main seals anyway if spring is bad or not while your there ?

[@BornAgainBoating]

Depends on how often you do the impellers. Some of these engines get impellers done every couple of months. So we don't change them if the spring is still good, just to save a little bit. If doing an impeller every couple of years, yeah, I'd say to change them anyway :)

[@svenop]

The oil seals and o rings on the pump housing are ok to reuse? From the video the house was just placed back on

[@BornAgainBoating]

Yes, unless the housing got hot and melted, the o-rings and cups can be reused, just replace the driveshaft seals if the spring is broken and then the water pump housing gasket on the bottom :)

[@svenop]

@@BornAgainBoating thank you!

[@svenop]

What engine oil are you pouring in there? Doesnt look like a yamaha jug. Is there a cheaper alternative?

[@BornAgainBoating]

It's Yamaha oil but we have it in bulk, so the jug's are just jugs ;) it's usually cheaper to buy it in bulk somewhere, than to buy the individual gallon jugs!

[@bocabretts123]

Incredibly helpful! I've got twin 300s. Should I prefill my boats fuel filter with 90rec or it doesnt really matter? Also, looks like I can change engine oil with the engines in water?

[@BornAgainBoating]

Yes, prefill the water separators, here's some more info on it: www.bornagainboating.com/pre-fill-fuel-filter-water-separator/ And yes, you can suck out the oil while in the water, just make sure and tilt the engines up first to get the oil out of the heads. When you suck the oil out, it usually leaves a little bit in the bottom of the pan. So just check the dip stick as you pour in the new oil to make sure you don't over fill it.

[@bocabretts123]

@@BornAgainBoating Got it thanks so much. It's nice to know I can knock out a lot of the service in water, other than change lower unit oil, change water housing/impeller, check prop shaft for line.

[@jazzyj2243]

Gee if there in good condition, would be a great buy for someone looking for used motors. Is there anyway to cheat the number of hours a boat engine has, if so, I'd be suspect of that too.
