I have a small aluminum boat. It is rated to 25HP. Boat was built in 1961. It has a Mercury 4HP Fourstroke. Be luckly to go about 12-14 MPH. I want to rebuild a 1961 Evinrude 18HP. But I bought a like new 25 HP Powerhead. I have tried to find specs on this motor but cannot. The weight, gear ratio, prop size, etc. But since HP was rated at the powerhead and not the prop how much HP is a 1961 E-rude 25HP good for? Thanks, John:cheers:
