Just wondering why there is no type of cam like a VTEC in a Honda in a boat? Wouldnt you get better all around power?
For everyone who dosent know how VTEC works.... For every 2 Valves, there are 3 lobes on the cam, when the engine gets to a certain RPM, a pin is put in place and the valves go from using the 2 fuel efficent lobes to the 1 lobe with more rise and duration.

the vtec adds horsepower at higher rpms. a boat motor just uses the higher lift lobes all the time you need the low rpm torque to get on plane. I think of a vtec not as a motor that pulls harder at high rpm but one that doesn't pull at all untill the rpm gets up.
Sorry but I work at a honda dealership and I'm so sick of hearing "my rice burner is fast cause its a vtec."

I know, I hear that every day at school!! Have you ever heard a Honda 1.6 w/ VTEC at 9,000rpm? That is one of the neatest sounds I have ever heard...

It de-rates the power down low, not adding power up high.

There has been a form of the vtec motor in a boat. Toyota motor corporation marinized the same V8 that they put in the lexus GS400. the VVTI motor was converted for marine use by toyota I believe 4 years ago, they could not decide on what to do with the motor( choseing a builder to sell them to) so they got into the marine buisness themselves. Along came Toyota Marine Sports. They chose to enter the skiboat market(still not sure why that highly competative niche market?) They built boats for about 3 years, then closed up shop. My mother worked for them until she went to chris-craft.... The boat was a pretty nice boat... they just could not get the "back office" to run smoothly enough to stay open.

And they did put a couple of ZR-1 engines in boats. (sure like to know what they are worth!) The ZR-1 had a valve that closed off the intake port to one valve to improve the low rpm torque. Not as sophisticated as the Vtec, but hey, it's was pretty hot in it's day.

I just thought about this... Wouldnt It help big motor boats with breaking drives? It would keep power down until a certain RPM, then give more top end?
