Just for the record, if the motor is tuned up decent, and it has already been started and run within 5-8 hours......a V6 really isn't as hard to rope start as you might think.

I just figured it would have be a hell of a pull.  That thing runs like a top.  couldnt be happier switching from a Opti to a carbed motor.

OPtimax is so over engineered. way to many things to go wrong.  Mine was a small one 75hp  and i had 1000 hours on it and it ran fine but i knew it was a metter of time before it popped.   Look at boat online with higher hp optis and almost all of them have a new power head at 300-500 hours...   when they run, they run great but when they break its so hard for the garage mechanic like me to figure it out.   Ive been doing 8 trips per month this year with my ole carbed motor.  fresh gas is the key in my opinion, dont let them sit

I've had a half dozen or so 3cyl. Opti's come in with an unstable idle issue fresh out of warranty.   I've yet to cure one of it, and neither has anyone else to my knowledge.    It's obviously an emissions control issue that the ECM can't sort out.   I'm a mechanic, not a computer wizard.   🙄 

I can control the info being fed to the "brain" .... but I can't control what the "brain" decides to do with it.  

I hate to sound conspiratorial, but I almost suspect that the "brain" is programmed to start running like $#!t after a certain time-clock has expired, even though everything mechanical is 100% fine.

My opti 75 i had flashed to a 115 and it was a monster on my 17 ft tracker. only issue i ever had was a coil.   But the small optis never had as many issues as the 175 and bigger.    

Still wish I had your old motor on my boat.  I love my boat and the 60 just sips the gas but I wish it was a tad faster.  I think you butt dialed me last week at 12:30 in the morning?  or perhaps you meant to......i was sound asleep sorry man.
