I have a Boston Whaler also! Join the Facebook Group 'Everything Boston Whaler'. The information found in there is priceless, and someone may well have everything for the Jet Boat. I know I have seem images of them and some of the 8,400 members have owned them. The group owner is Jeff Rohlfing. Tell him I sent you.

Nothing leaps of the page on Google looking for the engine.

A search for the boat though shows it is the Boston Whaler Rage and does bring up some information.

yamaha like all engine manufacturers are controlled by the EPA in the countries they are sold
In most countries the use by date has been established and 2018 is the end date that they can be sold with the start date being as early as 2015
So to comply with EPA requirements, yamaha would be allowed to sell off existing stock but the retail section ( local dealers ) would be restricted form selling them in certain countries
So to answer your question
No yamaha would not be making 2 strokes after 2015 as they could not sell them so any you see would be existing stock in dealers being sold off

Black plugs indicate carbon build up. Try starting with ether sprayed into carburetor. If it fires, clean fuel system with spray and additive. Use the fuel engine was designed for.

It means your engine's cylinder volume from the piston being at bottom dead center to top dead center divided by it's compression volume (the volume in just the cylinder head with the piston at TDC) equals 6.8,
which is a very low compression ratio.
It is not a measure of PSI. It's the ratio of how much the gas/air mixture is compressed before ignition.
The engine is taking 6.8 units and compressing it into 1 unit before ignition - a ratio of 6.8 to 1.
