I like to drive my boats near max RPMs for hours at a time. My Scarab 165 has a 300 HP Rotax engine and I drove it around 7100 RPMs (which makes it go about 50 MPH) for the majority of the 150 hours that it has on it before the engine blew up (literally a big hole in the engine). The dealer has had the boat for nearly a month now and we are still waiting on a warranty approval. The boat was maintained exceptionally well, so it has me wondering if that 300 HP Rotax engine is really designed to be driven around 7100 RPMs 90% of the time. The engine is made for jet skis, and in a jetski 7100 RPMS from that engine will have you going over 65 MPH. I don't think many people ride their jetski over 65 MPH 90% of the time they are driving it.
I also have two Seadoo Sparks with 90 HP naturally aspirated engines. I ride these things even harder, at full throttle about 95% of the time that I'm on them (because they only go 45-50 MPH at full throttle). My two Seadoo Sparks have a combined 400 hours of engine time, and I've only had 1 minor engine issue that entire time.
I recently got a Yamaha 222XE with the twin 1.9L naturally aspirated engines. I like to cruise at 45+ MPH, which is around 7200-7400 RPMS. Is driving the boat like this 90% of the time going to make my engines blow up? I know that these engines were first introduced a couple years ago, so there's likely not a lot of information on them, but the previous generation Yamaha engines were around for about a decade and were very similar. Does anyone know how well the previous generation of 1.8L naturally aspirated engines would hold up being driven that hard?
