Need to knwo what year to tell you how high the HP can go. If it's a looper i wouldn't push it any higher than 115HP, if it's a crossflow then it can be taken up to 140HP(but will drink as much as any 150 V -6 out there can). loo kat teh cylinder heads, if they are rounded without removeable head covers it's a looper, if it has a bunch of bolts on the cylinder heads with removeable covers it is a crossflow. Also teh looper will ahve a 1 piece block whereas the crossflow will have a removeable chest between the heads for teh exhaust cavity and it will also have covers on the outside of the block over the cylinders for the intake ports. If it's a looper I would jump on it as they are great engines and the 60 degree loopers were some of the most reliable outboards ever built. Crossflow engines are good engines, but tend to be thirtsy. they are reliable and simple though with ALOT of parts out there for them cheap. Also they are lightweight for there HP. Look on the port side clamp bracket and see if you can find a serial number on it that ends in 4 letters.
