Are you looking for the Yamaha OEM transom plate with factory 160mm taper or the aftermarket modified 155mm transom plate?

You can cross reference the OEM part numbers for the transom plate in...

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.

Unlike a carb engine, the fuel does...

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.

Added Stoltz rollers to protect hull from corner steps on Triton single PWC trailer

I just remembered this thread from 2019

Knock sensor: Using 87 (or 89) octane gasoline in Yamaha SVHO engine

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.

My ‘more than’ advice comes in part from people new-to-Ficht hoping (or expecting) that their barely, just barely,...

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.

A slow multi-second ramp up in...

My understanding is that the ‘Low Octane’ tune is still configured for 91 octane fuel, but less aggressively so.

The flywheel (magnets loose or damaged) and the Ficht stator (damaged or incorrectly wired to the 12-pin plug) are the primary and more common causes of reduced injector voltage (given that the EMM...

Larger diameter tires (and perhaps wheels) is an upgrade.

More than 20 volts DC required in order for the fuel injection system to start the engine. 17 volts is much too low

I will suggest a safety strap (or chain) added to ensure the ski stays on the ramp even if the winch releases unexpectedly, while unattended.

I composed a similar reply a few days ago, apparently it did not actually post :-?

The CDI can remain connected directly to Red/Purple wire group.

Only if you experience warm engine restart problems would the CDI need to be connected instead to Orange wire from the...

What matters is the air density inside the intake manifold and inside the cylinders, relative to the fuel injected on each combustion cycle.
