I have a 1986 18' Seacraft with a 1991 Mercury 200 offshore engine on it. The engine was on the boat when I purchased it and had a seized piston due to an oil injection problem. I too looked long and hard at re-powering with a smaller engine. However, I found that some of the smaller engines (175, 150) are actually HEAVIER than the 200. I don't remember the exact weights, but I spent a lot of time on the NADA site. Someone also told me that the 200 v6 block is the same one used on mercury's 150 and 175. The only difference is the bore, and some electrical. Anyway, I decided to re-build the engine myself and removed the old oil injection system. It is now a pre-mix engine and has been running strong for about 3 years. While I will agree that the horsepower may be a little much, the weight does not seem to be a problem. I rarely drive the boat more than a good cruise speed, but it is nice to have the extra power if you need it....Toadfish
