This one has some footage of me doing the lower. It was 110 degress outside in Seattle. (no joke, it actually was 110 degrees). Which caused he camera to blur a little. Later next month when I replace my entire water pump (as I'll have 300 hours on it), I'm going to do a complete remake video of the process. ruclips.net/video/hmqInREaC0A/видео.html
Thanks!! The timing was good for putting this video together. I wanted to cover the basics and show everybody that it's just not hard work. Without video recording anything, I can get it all done in about 4 hours without rushing.
For comparison on my Cutwater C-28 with inboard diesel. Volvo specifies a 200 hr maintenance interval on the D4-270 (or yearly). For most people, that's probably an oil change once a year. The D4 takes 12 liters of oil, two oil filter, no spark plugs, and no zincs. I don't need to pull the boat from the water for the oil change, but I still have to do it to replace the boat's zincs regardless.
Great video. Thanks for taking the time to record your process. I've seen others pre-fill the fuel/water separator with gas before screwing it on to help prime the fuel system. Have you ever had issue cranking the motor waiting for that filter to re-fill with gasoline? Do you do anything to prime it such as a primer bulb or just turn the key and let her rip? Thanks again!
Thanks for watching!! I've pre-filled the new filter with gas in the past. This time I just swapped out the filter and used the primer bulb to pump fuel into the filter. Either way, the engine turns over quick and starts right up.
Thanks so much, Martin and Lazina, for taking the time to share all this info on the 100-hour maintenance. You've given me the confidence to try it myself, and I'm looking forward to it. First time for me. I've just ordered the F300 hp service manual as suggested, and will take it from there. Hoping it will list the tools needed. If it doesn't, I hope you won't mind if I ask you for a list.
That's fantastic to hear! Thank you for the feedback. If you haven't checked out our website yet, you may find this useful. I have a full spreadsheet of part numbers, for doing the routine maintenance on the F300, T9.9 kicker and the F2.5 Yamaha. This is what I use for myself. www.letsgochannelsurfing.com/yamaha-tech-talk
Does your 4.2 have a timing belt as many of the older large Yamaha's? If so what is the recommended replacement interval? The older ones were pretty frequent and the process was complicated and time consuming resulting in a large shop bill. This was according to the YT Boating Life where the presenter says he is a certified Yamaha mechanic in Florida at a large dealership. Kind of interested as I had never heard of anyone changing the belts around here and some charter motors have several thousand hours (2-3 not uncommon) on their engines. Furthermore he stated that they were an interference engine which means if that belt lets go your engine is trash. The pistons smack the valves and the shrapnel scores the cylinders. New top end required! Since the shop bill would be several hundred dollars and the hour value was only in the two to three hundred as I recall with a time interval of two or three years also even if the hours didn't qualify. A definite consideration when choosing a maker in buying an outboard. What does your manual say regarding this?
Hi guys. I've been watching a few of your videos and just subscribed. Great content. I am an aspiring R27 owner. I'm working on putting together what I need to get one. Your channel has been an inspiration and sold me on the boat. I'm looking forward to binging the rest of your videos. Keep em' coming. BTW, I saw your hat in this video. You may have mentioned before in another video, but did you serve on submarines? Thanks again for the content.
Thanks for watching! I served onboard the USS Tinosa, SSN 606 (decomissioning crew), but did most of my sea tour on the USS Georgia, SSBN 729, Blue Crew. A-Gang, MM1/SS (auxiliary division). 12 patrols in total.
Excellent DYI video with lots of great tips. With the care you give your 300 what would you estimate your total hour life of the engine before you would replace or rebuild the engine? Looking at a Used R-27 with 1150hrs, on it, that just completed the Great Loop, and would like to know how many hours of life is left in it? 7000 to 8000? Thank you in advance and keep the coming!
With the video being over an hour, we didn't include it in this footage. We have another video that shows the impeller replacement. It's not the best video, as it was 110 degrees outside (literally, it was 110 degrees, in Seattle). The heat caused the camera to blur things a bit, and I was rushing as it was hot out. I've got it on the list here in the next 2 months to film how to do the lower, with more detail, as mine is due yet again in another 30 hours. Start around the 19:00 minute timestamp. ruclips.net/video/hmqInREaC0A/видео.html
We put so many hours on the boat, I've changed my routine to replacing the impeller annually (at the end of the season). I usually do the 100hour engine maintenance twice a year. Every 300 hours I replace the entire water pump assembly in the lower unit. This video was long enough that I didn't cover the lower unit much. I'll be filming the lower unit in more detail this weekend actually, as I replace the entire water pump assembly.
I agree with you, for a car. The F300 oil filter is mounted upside down. When you remove it, there no oil in it as it all drained out. If you were to fill it with oil, it would dump out all over the engine before you could get it back on. This set up makes it nice in that changing the oil filter with the engine in the water is possible since there's almost no oil that can fall out of it, hence, there isn't much oil to drip out into the surrounding water.
Very educational. I don’t know how I missed these. Thank you.

Once again, a very informative and comprehensive coverage for the DIY group. Thanks again!

Thanks for taking the time to make this video. I enjoyed watching it and picked up a couple of tips.
Thank you for your excellent . Great idea of using a quick-connect for the engine flush, genius, saves so much time and losing gaskets, etc.
Glad it helped!

You guys have an excellent channel!!! Thanks
Thank you so much. Thanks for watching.
Thank you will do this on my next hundred hour service. Great work.
Thanks for watching! I'm glad you found this video useful.
Thank you for all the detail with this process!

I want to thank you personally for posting this. Feedback like this is what keeps us going and having fun putting these videos together. -Martin
Great content. Thanks!!

Thanks for watching! The timing belt is serviced/replaced every 1000 hours. The 4.2 liter f300 has a 97pct no warranty claims rate with Yamaha.
Great video, thank you!
Thanks for watching! I’m glad you found this video helpful.
Great video thanks
Glad you enjoyed it. Thanks for watching!
Great video, guys. Thank you so much.
What log book do you use, Martin? I’m going to get one before my 20 hr. service.
I have just a normal ship's log, for logging trips, fuel and maintenance. Old school pen and paper.

I would expect to get over 7,000 hours on a Yamaha F300.
You didn't change replace/inspect the impeller in this 100h cycle?

Do you verify the spark plug gaps before replacing? I’ve seen some variation in the spark plug gaps out of the box.
I do verify the gap when my parts order arrives at home.
@@Letsgochannelsurfing Do you know the gap? Excellent video! Thanks!
Hi, got a 300 hp 4 stroke trying to locate pressure release valve please help.
I have one complaint you are not putting in the oil and the filter
non-metallic anti seize?
I usually just coat everything with Yamalube marine grease.
Why don't you inspect the water pump impeller isn't that on the hundred hour service
We put so many hours on the boat, I've changed my routine to replacing the impeller annually (at the end of the season). I usually do the 100hour engine maintenance twice a year. Every 300 hours I replace the entire water pump assembly in the lower unit. This video was long enough that I didn't cover the lower unit much. I'll be filming the lower unit in more detail this weekend actually, as I replace the entire water pump assembly.
Engine oil filter inside not putting oil without oil fitted that is wrong
I agree with you, for a car. The F300 oil filter is mounted upside down. When you remove it, there no oil in it as it all drained out. If you were to fill it with oil, it would dump out all over the engine before you could get it back on.
