    '84 70hp any opinons

    I'm looking at swapping power from a '84 115 merc to a '87 70 yamaha. The merc is just way to much for my '85 15' skeeter. Any problems with the 70hp? It has a rebuilt lower unit and fresh bearings in the top. The skeeter is rated for a 85hp, would it be to under powered with the 70? Thanx Dan
