Your 90 model was rated for a 235HP engine IIRC. It is a bit on the large side for a V-20, but it can handle it. Just hang on because if the engine is up to par with a good prop, low to mid 50's is in your future. And if it is in fact an 87 engine I would shy away from it. The 86-87 200/225's can be problematic and ratehr tempermental. OMC used a 2.7L engine for 86-87 for the 200/225's, and the samll bore engines overheated and had alot of other issues with them. The good side is if it is a factory replacement powerhead, it will be the 88-92 style large bore 3.0L engine, and they were solid as a rock. So look at teh engine and see if it has the model number on the welch block of the block of the engine. If it does get teh numebr and cross check it to the year and see if it is an 87 small bore engine.
