Valve Adjustment F150 TXRD

The future will be the demise of the ridiculously inefficient piston engine!

I shall not live long enough to see it.

What type/design do you think will replace it?

Will the masses be able to afford it?

Already reasonably affordable electric (hybrid), that out perform any gasoline car in many ways ( look at acceleration figures) except for toxicity and other dangers around the batteries.
The time it will take is directly proportional to the power and influence that petro companies will continue to have (always been that, there are even better engines invented that these companies forced into oblivion eg Saritch)

It is nothing at all for a boat to have a 100 gallon, 200 gallon, 300 gallon fuel tank. Compared to an automobile that might have a 25 gallon tank.

An automobile coasts a good portion of its life. A boat is being powered uphill all of the time. Load a boat down with battery weight and it only gets worse. Battery powered automobiles today have squat for range even though they coast a bit. Or run on minimal power.

I don't see battery technology being able to power a boat for decades and decades and decades. Like I said, not in my life time.

I finally checked my F225 at ~1400 hours

Bought two shims, for adjustments that were juuusst barely out.

(too tight, IIRC)

Had to special order; my local yamaha dealer (with a master tech) doesn't stock them....

I don't know if Yamaha pulls the same trick with their marine engines as they do with some of their motorcycles. They don't provide enough range in thicknesses of these shims. When new their engines are very quiet in the "tappet" clatter. When it becomes evident, even to the point of annoyance and to the attention of others, the increased gap measure is still way way less than the next shim size available. I did not reshim an engine that went this way as it was obvious to me that I would be increasing the gap (albeit to within their specifications!).
This makes me think they really have a greater range available in production and shim to a far less gap than what they specify the public should do, just to reduce the sound to make the new product attractive to buyers.

There is a car (Tesla), admittedly very expensive that will do 600 miles at 60 mph on one charge! Tesla does not advertise or spruck or give out figures, but has a massive waiting list (unprecedented demand in the industry). Go check, you need to look hard and have friends in the know apparently.

I just bought a Hot Cams shim kit for my Yamaha MC.

The difference between those shims is .05 mm's :

Hot Cams, Inc.


The genuine Yamaha shims:

The genuine Yamaha have a wider gap between the shims for adjustment. Besides being $13.00 a piece for a Yamaha shim, the Hot Cams kit is $90 with a better selection...

[zenoahphobic]

I meant to add that the weight issue is more critical in the marine environment.
However 300 gallons is also a lot of weight. Already Lithium batteries carry as much "energy" by weight as liquid fuel. Motors are fractional in comparative weights (20 HP one pound!)
You need to add external charging capacity like solar and " regenerative" sources such as wind, tide , salt water as an electrolyte or capacity to make a battery (ref Gilligan's Island!). Before you raise it wind is available not only at rest but underway (think cross wind) and tide at rest (anchor).

Thanks to Aftermarket manufactures. Your parts diagram calls shims " pads, adjusting".
The bike I had that experience with was the R6, and didn't bother as that bike was eventually sold. I have a number of trail/enduro 5 valve head bikes, that I won't bother to make an inspection as regulary as most people seem to do. I'll attend to it if I notice a change. Never changed a shim in my life, maybe because I don't trash them beyond their significant reliability, I think.
There is considerable over maintenance out there, more I suspect to seek that extra 1% performance. Just get a bigger bike, all mine never see WOT, simply because I'd either fallen off, be dead afterwards, be made broke with fines, or be carted away in handcuffs.

Here in the land up over we have a TV show called "Cops". I always like it when some yahoo tries to out run the cops on a motor bike. Especially the ninja warrier style bikes. It never turns out well for the rider. Hard to out run a radio transmission at a billion miles an hour.

I do feel badly for the motor bike.

Cops show- isn't it amazing? Based on the intelligence exhibited, we should all be millionaires, right? Damn show has been on for at least 20 years....

Yep, ships have travelled all over the world without engines for centuries. Used Zip fuel.
There are now again on large merchant as well as large passenger liners (just on economics, to save fuel, to save money).
Yep I see a ski boat no noise, no smell, but a strange looking flexible solar cell turbine . If it is not in my lifetime then it is because I may get electrocuted as they let these things out into the community to be tested.

My engine IS a slightly detuned R6 engine, same shims, same procedure.

I have 22,000 miles on it and will wait till 26,600 unless something happens before that before I do a check. Its a bit more involved the OB, but same procedure. And it's very rare it goes over 8,000 much less 14,000. Most running around town is between 4 and 6,000 RPM.s

Once they perfect the battery , all will be electric.. The piston engine after about a century is just about perfected.. hate to see it go and someday it will go. Not in my lifetime I hope !

Its been more than a century that the piston engine has been "perfected".
I can't call 25% energy conversion to propulsion, and the other 75% loss as heat that still causes unsurmountable problems with modern engines, as perfection!!
