+1111 on the top bearing......will ruin your day and then some. I had a 97` 225 and the only thing i had go bad was the fuel pump.....after 10 years. Change the plugs every year or two, new water pump every 2-3 years,MIX the oil, and check the top bearing bolts regularly. they are kind of hard to get your fingers on, so take an open end wrench and just feel of them .
