For traditional lead-acid powersports batteries, the manufacturer recommended off-season storage method is to not just leave the battery sitting.

Just sitting by itself, a fully charged lead-acid...

Not okay.

A Ficht engine is not lubricated by the idea of oil. It is lubricated by actual 2-stroke oil, delivered to the air intake system via the oil pump.

If at all possible, find a way to test ride each machine. For more than three minutes.

Different hulls have different ride characteristics. Beyond engine power and specs, you may find you dislike...

The 2.5mm step is a sharp diameter transition that creates swirling water eddies around and beyond the metal lip. The impeller blades are only a few millimeters downstream.

And every few years, even if running hours are not accumulating in a hurry.

Especially in salt water, but even with fresh water riding.

An alternative method of keeping the hull away from the rear end of the tongue rail.

There two choices are rather different in terms of hull design, ride characteristics and some features.

What kinds of riding do you expect to be doing? On what kinds of water? With passenger...

This thread is now a sticky.

Also moved these corner step protection posts into a separate thread (this thread).

Step corner protection moved to new thread.

A salient point from that post is that once the Yamaha SVHO ECU determines the fuel...

I shall defer to your observations regarding the actual voltage threshold.

Aftermarket Start/Stop LR modules for Polaris PWC seem to be uneven in terms of reliability. Some don’t work right out of the box, some only last a short while. And I suppose some work for longer...

Perhaps you should buy such a tool?

Injector voltage should jump up to right near 45 volts almost instantly after engine starts and climbs to idle RPM (which is 1150 RPM). Like maybe one second or so.
