Search my posts on this. It seemed there were alot of oppinion but very few with experience (I also refer to the other Whaler web site). I just went through this on my 1963 Nauset. The old engine was an original Johnson 75. The bottom holes are just above the edge of the slash well. They are also a different distance apart than what is standard now.
Mercs and Hondas will not fit without major modification. I don't know about E-Tecs since I don't have any dealers close by. Suzuki apparently works (there is another owner on this site that did one....but I don't want to speak for him on how well it worked). I went with a 2001 Yamaha 4 stroke 100HP. Yamaha bolted up without ANY modification. The original (non-standard---- to todays standards) transom holes matched up with the engine mount. Yamaha has an extra set of holes in the mount that others don't. On SOME new Yamahas the bolt hole was eliminated in blace of a "blind hole" meaning that you can't through bolt it, you have to run a bolt from the inside of the boat and screw it into the engine mount (if that makes sense). The Yamaha lines up nicely on the hull. It must be sitting in the right place because I'm getting 46 MPH on GPS. Contact me direct if you want pics or greater information.
