does anyone own a optimax i just got a n2005 135 optimax   ive never had a motor newer than 29 years old and i was wondering how much i will love it compared to my  29 yearold  150 merc that i had to bribe each time i needed it to start    hows the optimax on fuel efficiency and noise also i used to have to mix my oil and gas in a canister then pour it in now i just fill up the tank and the motor mixes it for me correct?

No more mixing!!!  To me, that's the biggest advantage of most newer motors.  Just make sure you do keep oil in your oil tank.  Congrats!!!

I run an Optimax on the back of a Triton TR20. It is an awesome motor

that is very quiet and fires right up.

You are correct about just filling the oil tank and letting the engine

do its own thing.

As far as gas mileage, I have never seen a motor that does so well. My

engine tops out at 5,250 RPM's and if I run in the area of 4,000-4,200 RPM's

I can get in the neighborhood of 6 MPG on gas. I know that isn't a lot by

vehicle standards, but when it comes to big motors on big boats it is great.

Take Care,

You're going to be happy with it.  Fuel injection vs carburetor is no comparison, but the Optimax on my boat (a 225hp) loves the Optimax 2 stroke oil.  

Good choice, and good luck
