Those #+%^ engineers!

Problaby why I have quite the assortment of battery maintainers on everything with estart.

The schedule in the automotive market is brutal, with a need to release new models each fall probably routinely cutting short development efforts and debug time on new designs.

Might have been true once, but unless there's a major revision, modern vehicles don't change all that much from one model year to the next.

I bet it's really hard to pull start a larger 20+hp 4 stroke with or without a decompression valve imo.

I have a 2006 Yamaha Kodiak ATV. 450cc - and it has a pull starter in addition to the electric start. Twice in the 20 years I've owned it I've had to use the pull starter because the battery broke. Yes, broke - I could get juice by tapping on either the positive or negative terminal but otherwise no power. No compression release. Procedure was to bring the engine up to the compression stroke, crouch down, and then stand up while holding the arms straight. No way I had enough strength to "pull" start the engine just by pulling with my arms. Luckily the Yamaha was a real easy starter - one revolution of the engine, hot or cold, and it will start and idle. And it doesn't need the battery to run once the engine is running.

When I was an engineer for the government, all servicing had to be taken into consideration

A while back there was a big to-do about the price of things such as hammers in the Defense Department. Could this be a reason? I imagine that something used to pound nails all day would be a high maintenance item.

I know, this isn't the "Groan" thread. I'll show myself out now.

Aww well..an engineer speaking here, once chief designer at a now defunct wheel loader manufacturer, then R&D engineer at a slurry applicator manufacturer, and after an accident with nasty brain injury, engineer at a company that builds truck superstructures such as container systems and cranes.

You can nag and whine all you want, but when the plan is made on the shop floor, it will always be more expensive than to fully engineer it. Because paper is more forgiving than steel (although i understand that there are "engineers" out there that never seen practice...)

That's for sure.
Around 1990 I had a 115 hp Mercury outboard boat motor. It had electric start and a pull rope. I tried starting it while parked in my garage. Even standing on the ground I couldn't pull that rope. So I put some jumper cables it the boat...it had 2 batteries up front for the trolling motor.

Having worked as an engineer in a defense industry, I know something about this. The problem wasn't the design, it was the inflexible standards and the procurement process. If an item needed 4 bolts we had to require full material certification and traceability. Eventually we made some progress in being able to buy larger quantities to maintain in stock but many things are one of a kind.
