225 Yamaha Four Stroke 23ft 87 Sceptre

Both are simply working within the NAEBM requirement that advertized HP must be within +10% of the actual HP. Yamaha actual is near the -10% limit while BRP is sandbagging by the full +10%, which they seem to be doing on everything but the highest rated versions of each powerhead, i.e. the "200" hp 2.6L and "300" HP 3.4L models.

In this case, while neither is telling the truth, I suspect most folks would prefer to be pleasantly surprised by more power than expected rather than disappointed with "less than advertised" performance!

I agree, and BRP using Yamaha's overated 225 in a comparison was a good marketing play.

I'm trying to find the article but somebody dyno'd several outboards at their first service interval and found hp ratings that dropped as low a 20%. It was a good test from an independent lab that took took them all to stall off the crankshaft output and not the prop shaft. It was a few years back but was really interesting to see how subjective rating were. For me the best comparisons are shootouts on exact vessels.... Nothing beats real world testing by independents.

Kent don't turn out the light in the man cave at night. Them Mercurys in there will eat
them Yamahas.
