I just checked on greenhulk's classified section and didn't see any svho intercoolers for sale there. Maybe I didn't do a thorough job of searching that site but I think it's more likely that the "all the time" statement as used excludes now or currently. Whereas I define now or currently as within the scope of all of the time.
note that the riva gen 2 equivalent kit sells for $1,000 which is better than the stock price of $1,570 currently Offered by Yamaha sports plaza.

As for the kW to hp conversion, I'm not confused and am not trying to make the determination confusing. The kW output is printed on a placard mounted on or near the engines. This is where my kW figures are from. Here is a link to the conversion site I used and the formula is cited in other threads here. http://www.rapidtables.com/convert/power/kw-to-hp.htm
Not sure what "best estimates" source(s) is (are) but if the conversion formula and source for it are accepted as accurate for the 1.8l n/a engines they should apply equally to all of Yamaha's other engines as well (I.e., kW on the placard x 1.341 = mechanical hp).
Unlike @swatski I have not been in many 230s (as a guest I presume), just the one sx230ho I owned and used heavily for four years. There is a distinct difference between the sounds that the 1,052 cc and 1,812 cc motors make, with the 1,052 reving a lot higher by about 2,500 rpm at wot. the print out I have for my 2010 242 LS shows 93 db whereas a 2015 242ls with quiet ride tech came in at 87 db at wot (you tube review) so quiet ride makes a huge difference in that the db scale is logarithmic so a small reduction or increase in db equates to a larger reduction or increase amplitude or power, keep in mind these are twin engine boats. as for the 190, 192 and 195 with quiet ride boat test results are 98 db , 100 db and 92 db at wot respectively. So as @swatski stated, the early 190s and 192s were the loudest of the Yamaha line when they were first introduced but they are all bad since according to web md constant / consistent exposure to any anything over 85 db is harmful.
Again, just something more to think about as the decisions on what to buy and for how much are determined.
