My 115 HP Yamaha V-4 outboard turns 30 years old this year. It’s been a great engine. I still like taking it out on my 17-1/2 ft Campion. To me it’s the smell of victory! Any other two cycle fans?
Anyone running classic (old) two cycle outboards?

Just gave my 1965 6HP Evinrude to my grandson. Hopefully he'll have as many enjoyable fishing trips with it as I did.
My 50 hp Yamaha and 9.9 Evinrude are both two cycles. The Yamaha is fancy and has oil injection.
I have an 80s Mercury 2.2 hp that I believe was made by Yamaha. The odd time I plunk it on the back of my portabote when I wanna go in really small lakes/ponds.
Nothing like the smell of two cycle exhaust while boating.
My last 2 cycle was a Johnson 115 HP.
Since then it's been all I/O

Still occasionally use a 1955 Johnson 10 hp. I know it's history and it hasn't seen a lot of use. Surprisingly it doesn't weigh more than a modern engine.

That’s amazing …
Does it use a pressurized fuel tank?
yes it does, the good thing about that is....if you stop and tilt the motor up, the pressurized tank will continue to send fuel to the carburetor and drip out into the boat. Fun sitting there is 1/4 inch of fuel smoking a cigar.
Best smell.

Went from that same Johnson to Merc OptiMax - better - then 4S - even better yet …
I luv the smell of 2 stroke in the morning. Mercury Quicksilver Premium Plus.
I say this with a grain of salt but I think the Johnson 115 was the last outboard a shadetree mechanic could easily work on. I look at the Yamaha big (300 HP maybe) outboards today and they do not look easy for a shade tree mechanic to work on. But they do not break very often so I am told.
For me I feel a GM 5.7L I/O is nice to work on, especially in a wide open engine bay.
Is shade tree mechanic the right description for a guy who works on his boat engine on the weekends? I mean no trees on the water. Maybe canvas top mechanic or Sunbrella top mechanic.

Yes - I remember wanting to test OMC CarbonGard (strong Techron) and how easy it was to look at all pistons (it worked a bit) …
I have replaced all three relays on my 140 HP Yamaha, motor up, motor down, and the starter relay. A genuine Yamaha starter relay last year was $140 US. I also picked up some Made in China relays that look identical, as spares.
Sure; If you work on the boat in the shade. Drain and refill the lower unit oil and replace plugs every 1 or 2 years. Impeller when the motor needs it.
