Re: Will a Merc 3.0 Manifold work on an OMC setup?
I'm not worried about the restriction of the 3" riser, I'm worried about the 3" merc riser mating with my 4" omc exhaust going to the transom/outdrive. I need to look into this more, if I can get the merc manifold and riser to mate up with the OMC J-pipe I'm probably going to go that route since the head ports will match up. <br /><br />Just had an idea.... uh oh.... how about removing the j-pipe, blocking off the outdrive exhaust, and running a thru-hull? That would solve my problems I think! I am in NJ and the guy with the manifold is in CT, about a 3 hour drive, I think I'll be making a trip this weekend to eyeball things over and get a feel for whether or not it's going to work. I can get the merc manifold for about $100 it looks like, or the OMC for $300. OMC riser is $104, Merc riser is about $80. From there, I would need another $100 (estimate) into the merc manifold setup for a stainless pipe and flapper out the transom. I have the holesaw...haha. <br /><br />I obviously have to think this over here......
