A 150 can be either a 2.0L, 2.4L, or 2.5L. The 2.0L 135/150's are the ones that sound like a pissed off dragster when they idle. The 2.5L is a solid performer, but from my experience is a THIRSTY pig of an engine. I had one of the 2.5L MERCURY 150 XRI's(same engine as a 175 carbed engine but was a fuel injected performance model) on my flats boat a few years back, and it would flat out haul A$$ when you got on it. I hit 60 a few times with it on there. The downside was it burned about 17GPH at WOT, BUT burned 12 GPH at 3800-4000 cruising. I've got an old 81 150 2.0L on an old bass boat and that thing sounds WICKED, but only burns 4GPH at a 3800 RPM cruise. If you could find an old 2.4L 175 though, that would be teh ticket. It will most likely be a chrome bore engine, but you can have them slleeved with steel sleeves if needs be. Check screamandfly as they LIKE there MERCS over there. And I believe your controls will work, but you'll probably have to change your tach out as MERCS are 12 poles and most FORCE engines are 20 pole.
