How many very new 4 stroke engines will be running trouble free at age 50 to 75 years old ?

The tariffs will raise all marine parts. Then a possible hard recession. Buy now if you can. A Honda dealer wanted $ 1300for brake pads & used rotors. American Tire wanted $1800 for new pads & rotors.
Many companies are now owned by very greedy Wall Street giants.

Went with my local garage. $ 626 Pads & rotors all 4 wheels. Labor was the biggest differences. Those big chains need lots more money.
Oh well.

Tax, tittle, dealer prep, destination fees and all the other scrap they add on will take it over 4K......

Only your state's sales tax.
No title, if you need one, that is a state fee.
No dealer prep.
Free shipping with lift gate truck service.
Free oil.
Free fuel tank and hose.
Free prop.

Last month, it included a free maintenance kit, (complete water pump, fuel filter, water separating fuel filter, spark plugs, oil filter, ).

Over the last 15 years I have bought 3 outboards from OnlineOutboards.com. A 25 Yamaha, and 3.5 and 5.0 Mercs. The bottom line price was significantly lower than from a local dealer. Hanging the motor and pouring in the free bottle of oil was the only prep needed.

Not a chance they will make parts NLA. All these companies and their planned obsolescence. They don't care about parts/maintenance after sales. It's all about Market share, and volume sales of new engines.

And the reason why the small block Chevy will still be around?
aftermarket support
Just like I can still get any part I need for a 4 bbl Quadrajet even though it hasn't been produced in 30 years!

Millions of SBC have been made over decades with a huge customer base. Racing,recreational,industrial,boats,SUV,trucks,cars etc. that put demands on parts, and upgrades. Aftermarket companies dedicate huge resources to making sbc parts, and cross references/interchanges etc. Also the abundant supply of used parts. The outboard engine market is niche and barely a fraction of the size of automotive.
2 stroke marine parts are more readily available because consumer demand. Most Outboards are durable and last a very long time if maintained. There simplicity, and design consistency make them easier to work on. 4 stroke engines can require manufacturer specific diagnostic programs to trouble shoot advanced EFI systems. Parts are also very expensive.

Wait are you saying I am replacing my 1957 Mercury for a 4 stroke?

Like the 351 too

Small block Chevrolets, Fords and Mopars are probably the best designed engines for long life and easy of repair, ever. I also love the AMC designed 4.0 liter six in older Jeeps, I have had one of those for 27 years....

I'll let you know in 30 years, my Yamaha is already 21 years old lol.

Parts availability is tied to demand. Generally, if there is enough demand, someone will make parts. It may not be the OEM, but someone will make it if enough want it.

Hence the parts availability for SBC, and even the availability for parts from OB motors from the 50s and 60s. A whole lot of those parts are from aftermarket sources. i.e. Johnnyrude 25HP - 40HP big twins and the venerable 6HP outboard motors. They were made for decades, and a lot of parts are still available.

Also, if you have a motor that shares parts from a lot of years or models, these parts will be more readily available. An example of this is the inline engines from Mercury. 2, 3, 4 and 6 cylinder inline motors often shared pistons, rods, bearings, carbs, cowling parts and more.

These rules will apply to 4 cycle OB motors as well.

There is one fly in the ointment. With the advent of computer aided design (CAD), it is much cheaper to design new engines, car bodies etc., than it used to be.

This means that OEMs can economically change the design of their products more often, to make them better or cheaper. That means that parts from newer engines are increasingly becoming different from parts of older engines.

 

[rolmops]

I have the feeling that specially low hp motors will all be replaced by noiseless clean very simple electric motors run off some advanced sort of battery. And their very simplicity and easily replaced parts will cause them to be the longest lasting outboards.

Like any motor, if it is taken care of and maintained it will be fine. If you need a major repair/ overhaul, the labor won't be worthwhile. Many home mechanics can do two stroke motors but can't handle the more complex four stroke engines. The additional parts and labor in a major repair will be the deciding factor.

 

[Lou C]

The two genres that will survive will be 4 stroke GM Marine engines and simple 2 stroke outboards due to simple basic design and availability of parts….

Very good point!
